Description

Technical Field

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

[0002] With the continuous advancement of technology, people are paying increasing attention to the air quality of their living environments. Air conditioners are a commonly used air handling device. When an air conditioner is cooling, the cold air blown out of the vent mixes with the warm air inside the room, easily causing condensation to form at the vent, thus reducing the user experience. Related technologies for air conditioners utilize dehumidification modes to lower indoor humidity, preventing condensation at the vents and achieving an anti-condensation effect. However, in environments that are not completely sealed, such as when windows are open, the dehumidification effect of the air conditioner diminishes, resulting in a slower or even no reduction in indoor humidity (e.g., when multiple windows are open). This leads to condensation still forming at the vents, resulting in a less effective anti-condensation solution. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide an air conditioner and a control method thereof that overcome or at least partially solve the above problems.

[0004] One objective of this invention is to address the problem of poor anti-condensation performance in air conditioners in related technologies, thereby improving the user experience.

[0005] Another objective of this invention is to address the problem of how to enable air conditioners to switch to anti-condensation mode more precisely.

[0006] Specifically, this invention proposes a control method for an air conditioner.

[0007] The air conditioner control method of the present invention includes: acquiring a first humidity value of the environment where the indoor unit of the air conditioner is located; controlling the air conditioner to operate in a dehumidification mode; acquiring a second humidity value of the environment where the indoor unit is located; and controlling the air conditioner to operate in an anti-condensation mode based at least on the first humidity value and the second humidity value.

[0008] In some embodiments, controlling the air conditioner to operate in anti-condensation mode based at least on the first humidity value and the second humidity value includes: controlling the air conditioner to operate in anti-condensation mode when the difference between the first humidity value and the second humidity value is less than or equal to a first preset difference; or, controlling the air conditioner to operate in anti-condensation mode when the ratio between the first humidity value and the second humidity value is less than or equal to a preset ratio.

[0009] In some embodiments, the control method of the air conditioner further includes: during the operation of the anti-condensation mode, acquiring a third humidity value of the environment where the indoor unit is located at first preset time intervals; if the difference between the first humidity value and the third humidity value is greater than or equal to a second preset difference, controlling the air conditioner to exit the anti-condensation mode; wherein the second preset difference is greater than the first preset difference.

[0010] In some embodiments, the control method of the air conditioner further includes: after the air conditioner operates in the anti-condensation mode for a second preset time period, controlling the air conditioner to exit the anti-condensation mode.

[0011] In some embodiments, the control method of the air conditioner further includes: during the operation of the anti-condensation mode, acquiring a fourth humidity value of the environment where the indoor unit is located; if the change difference of the fourth humidity value is greater than or equal to the first preset difference, exiting the anti-condensation mode and controlling the air conditioner to operate the dehumidification mode; if the change difference of the fourth humidity value is greater than or equal to a third preset difference, directly exiting the anti-condensation mode; wherein, the third preset difference is greater than the first preset difference.

[0012] In some embodiments, the control method of the air conditioner further includes: after the air conditioner exits the anti-condensation mode, and when the first humidity value is greater than or equal to a preset humidity value, executing the control of the air conditioner to operate the dehumidification mode.

[0013] In some embodiments, the control method of the air conditioner further includes: after the air conditioner has been turned on for a preset time, and when the first humidity value is greater than or equal to the preset humidity value, executing the control of the air conditioner to operate in dehumidification mode.

[0014] In some embodiments, the anti-condensation mode includes: controlling the compressor frequency of the air conditioner to decrease to a first preset frequency value; and / or controlling the fan speed of the indoor unit of the air conditioner to increase to a first preset speed value.

[0015] In some embodiments, when the air conditioner is in the dehumidification mode, the compressor of the outdoor unit of the air conditioner operates at a second preset operating frequency, and after the indoor temperature reaches a preset value, the compressor maintains the second preset operating frequency; when the air conditioner is in the normal mode, after the indoor temperature reaches the preset value, the frequency of the compressor is less than the second preset operating frequency.

[0016] The air conditioner of the present invention includes a memory, a processor, and a machine-executable program stored in the memory and running on the processor, wherein the processor executes the machine-executable program to implement the control method of the air conditioner according to any one of the preceding claims.

[0017] The air conditioner control method of this invention detects the indoor temperature before and after the dehumidification mode has been running for a certain period of time, respectively, to obtain a first humidity value and a second humidity value, i.e., the humidity change of the indoor environment before and after the dehumidification mode has been running. Based on the first and second humidity values, it determines whether the air conditioner should switch to anti-condensation mode. Furthermore, when the air conditioner cannot avoid condensation at the air outlet while running dehumidification mode, it switches to anti-condensation mode to ensure that condensation does not form at the air outlet, thus improving the anti-condensation effect of the air conditioner control method of this invention.

[0018] Furthermore, the air conditioner control method of this embodiment of the invention enables the air conditioner to switch to anti-condensation mode more accurately and promptly based on changes in indoor humidity, thus further improving the anti-condensation effect of the air conditioner control method of this embodiment of the invention.

[0032] The control method of an air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The air conditioner 100 according to this embodiment includes an indoor unit and an outdoor unit, with the indoor unit installed in an indoor area and the outdoor unit installed in an outdoor area.

[0033] The indoor unit of the air conditioner can be a floor-standing unit; or, the indoor unit can be a wall-mounted unit; or, the indoor unit can be other types of indoor units.

[0034] like Figures 1-6 As shown, the control method of the air conditioner 100 in this embodiment of the invention includes the following steps:

[0035] S100: Obtain the first humidity value of the environment where the indoor unit of the air conditioner 100 is located.

[0036] Indoor humidity can be detected using a humidity sensor. The humidity sensor can be directly installed at the air inlet of the indoor unit of the air conditioner to obtain a preliminary humidity value by detecting the humidity of the incoming airflow. Alternatively, the humidity sensor can be installed separately from the indoor unit in other locations indoors, such as on a wall or other electrical appliance.

[0037] S200: Control the air conditioner 100 to operate in dehumidification mode. The air conditioner 100 draws indoor air into its interior for heat exchange, causing the moisture in the drawn-in air to condense into condensate water. The condensate water is then discharged to the outside through its drain pipe, and the dehumidified air is then blown back into the room.

[0038] S300: Obtain the second humidity value of the indoor unit's environment. That is, after the air conditioner 100 runs in dehumidification mode for a certain period of time, the indoor humidity is detected again to obtain the humidity value after dehumidification treatment for a certain period of time, which is the second humidity value.

[0039] S400: The air conditioner 100 is controlled to operate in anti-condensation mode based at least on the first humidity value and the second humidity value. That is, the air conditioner 100 determines whether to continue operating in dehumidification mode based on the first and second humidity values. For example, when a user opens a window, humid outdoor air continuously enters the room. If the air conditioner 100 reduces the indoor humidity too slowly or even fails to reduce it at all using dehumidification mode, then the air conditioner 100 needs to be switched to anti-condensation mode. In anti-condensation mode, the air conditioner 100 has a higher outlet air temperature, preventing condensation from forming when the outlet airflow meets the indoor air, thus achieving the effect of preventing condensation.

[0040] When air conditioner 100 is running, the indoor humidity is first detected and a first humidity value is obtained. Air conditioner 100 is then controlled to operate in dehumidification mode, and after running in dehumidification mode for a period of time, the indoor humidity is detected again and a second humidity value is obtained. Based on the first and second humidity values, it is determined whether air conditioner 100 is suitable to continue operating in dehumidification mode, and then the choice is made to continue operating in dehumidification mode or to operate in anti-condensation mode. For example, if the indoor humidity decreases too slowly using dehumidification mode when the windows are open, air conditioner 100 is switched to anti-condensation mode; if the indoor humidity decreases significantly using dehumidification mode when the room is closed, air conditioner 100 continues to operate in dehumidification mode until the indoor humidity decreases to a level where condensation no longer forms at the air outlet, then dehumidification mode is exited.

[0041] Compared with related technologies, the control method of the air conditioner 100 in this embodiment of the invention detects the indoor temperature before and after the dehumidification mode has been running for a certain period of time, respectively, to obtain a first humidity value and a second humidity value, that is, the humidity change of the indoor environment before and after the dehumidification mode has been running for a certain period of time. Based on the first and second humidity values, it is determined whether the air conditioner 100 should switch to the anti-condensation mode. Furthermore, when the air conditioner 100 cannot avoid condensation at the air outlet while running the dehumidification mode, the air conditioner 100 switches to the anti-condensation mode to ensure that condensation does not form at the air outlet. Therefore, the anti-condensation effect of the control method of the air conditioner 100 in this embodiment of the invention is improved.

[0042] Furthermore, the control method of the air conditioner 100 in this embodiment of the invention enables the air conditioner 100 to switch to the anti-condensation mode more accurately and promptly according to the changes in indoor humidity, thus further improving the anti-condensation effect of the control method of the air conditioner 100 in this embodiment of the invention.

[0043] In some embodiments, the anti-condensation mode includes controlling the compressor frequency of the air conditioner 100 to decrease to a first preset frequency value; and / or controlling the fan speed of the indoor unit of the air conditioner 100 to increase to a first preset speed value. That is, when the air conditioner 100 is in anti-condensation mode, the compressor frequency decreases, thereby reducing the output cooling capacity and increasing the outlet air temperature, thus reducing the temperature difference between the outlet air temperature and the indoor temperature, and preventing condensation at the outlet. Increasing the fan speed of the indoor unit increases the air volume output of the air conditioner 100, thereby maximizing the overall cooling capacity input to the indoor environment while lowering the outlet air temperature, resulting in a more comfortable indoor temperature and improved user experience.

[0044] In some embodiments, when the air conditioner 100 is in dehumidification mode, the compressor of the outdoor unit of the air conditioner 100 operates at a second preset operating frequency, and after the indoor temperature reaches a preset value, the compressor maintains the second preset operating frequency. When the air conditioner 100 is in normal mode, after the indoor temperature reaches the preset value, the compressor frequency is lower than the second preset operating frequency. That is, when the air conditioner 100 is in dehumidification mode, its compressor operating frequency remains unchanged, and the compressor operating frequency is greater than or equal to its frequency during normal operation, thereby improving the dehumidification effect of the air conditioner 100 in dehumidification mode and rapidly reducing the indoor humidity.

[0045] In some embodiments, such as Figure 2 As shown, step S400 controls the air conditioner 100 to operate in anti-condensation mode based at least on the first humidity value and the second humidity value, including the following steps:

[0046] S410. Determine whether the difference between the first humidity value and the second humidity value is less than or equal to the first preset difference.

[0047] S420, If so, control the air conditioner 100 to run in anti-condensation mode.

[0048] In other words, when the difference between the first humidity value and the second humidity value is less than or equal to a first preset difference, the air conditioner 100 is controlled to operate in anti-condensation mode. After the air conditioner 100 operates in dehumidification mode for a certain period of time, for example, the air conditioner 100 operates in dehumidification mode for 30 minutes, the change in indoor humidity is judged by the difference between the first humidity value and the second humidity value, thereby more accurately determining whether the air conditioner 100 needs to switch to anti-condensation mode, thus ensuring the anti-condensation effect of the control method of the air conditioner 100 in this embodiment of the invention.

[0049] In other embodiments, such as Figure 2 As shown, step S400 controls the air conditioner 100 to operate in anti-condensation mode based at least on the first humidity value and the second humidity value, including the following steps:

[0050] S430: Determine whether the ratio between the first humidity value and the second humidity value is less than or equal to a preset ratio.

[0051] S440, If so, control the air conditioner 100 to run in anti-condensation mode.

[0052] In other words, when the ratio between the first humidity value and the second humidity value is less than or equal to the first preset difference, the air conditioner 100 is controlled to operate in anti-condensation mode. After the air conditioner 100 operates in dehumidification mode for a certain period of time, the change in indoor humidity is judged by the ratio between the first humidity value and the second humidity value, thereby accurately determining whether the air conditioner 100 needs to switch to anti-condensation mode, thus ensuring the anti-condensation effect of the control method of the air conditioner 100 in this embodiment of the invention.

[0053] Specifically, the first preset difference is less than the difference between the first humidity value and the humidity value in which indoor air will not condense at the air outlet, and the first preset ratio is less than the ratio between the first humidity value and the humidity value in which indoor air will not condense at the air outlet. This avoids the first preset difference or the first preset ratio being too large, which could prevent the air conditioner 100 from switching to the anti-condensation mode in a timely manner.

[0054] It should be noted that the first preset difference and the second preset ratio need to be confirmed based on the specific operating conditions of the air conditioner 100. The first preset difference can be obtained through experiments before the air conditioner is sold. For example, the air conditioner 100 can be tested based on the temperature and humidity of the region where it is expected to be sold in summer to obtain parameters suitable for the first preset difference in that region.

[0055] In some embodiments, such as Figure 4 As shown, the control method of the air conditioner 100 in this embodiment of the invention further includes the following steps:

[0056] S450: During the operation of the anti-condensation mode, the third humidity value of the indoor unit's environment is obtained at each first preset time interval.

[0057] S460. Determine whether the difference between the first humidity value and the third humidity value is greater than or equal to the second preset difference.

[0058] S470. If so, control the air conditioner 100 to exit the anti-condensation mode. The second preset difference is greater than the first preset difference.

[0059] In other words, during the operation of the anti-condensation mode, the humidity of the indoor environment is detected at first preset time intervals, and a corresponding third humidity value is obtained. If the first humidity value and the third humidity value are greater than or equal to the second preset difference, the air conditioner 100 is controlled to exit the anti-condensation mode.

[0060] Even when the air conditioner 100 is in anti-condensation mode, it will still dehumidify the indoor air to a certain extent. Especially when the room is closed, the air conditioner 100 in anti-condensation mode will slowly dehumidify the indoor air until the indoor humidity drops to a level where no condensation will form at the air outlet, at which point the air conditioner 100 will exit anti-condensation mode.

[0061] For example, after the air conditioner 100 switches to anti-condensation mode, the user closes all the windows in the room, making the room closed. At this time, the air conditioner 100 will slowly dehumidify the room until the difference between the first humidity value and the third humidity value is greater than or equal to the second preset difference. When the humidity of the indoor air is reduced to a level that will not cause condensation to form at the air outlet, the air conditioner 100 will exit the anti-condensation mode.

[0062] Among them, the third preset difference is greater than or equal to the difference between the first humidity value and the humidity value at which the air in the room will not condense at the air outlet.

[0063] In some embodiments, such as Figure 6 As shown, the control method of the air conditioner 100 in this embodiment of the invention further includes the following steps:

[0064] S401. During the operation of the anti-condensation mode, obtain the fourth humidity value of the environment where the indoor unit is located.

[0065] S402. If the difference in the fourth humidity value is greater than or equal to the first preset difference, then exit the anti-condensation mode and control the air conditioner 100 to run the dehumidification mode.

[0066] S403. If the change in the fourth humidity value is greater than or equal to the third preset difference, exit the anti-condensation mode directly. The third preset difference is greater than the first preset difference.

[0067] After the air conditioner 100 switches to anti-condensation mode, the user closes the indoor windows, creating a closed environment. At this time, the air conditioner 100 can dehumidify the room using dehumidification mode, quickly lowering the indoor humidity to a level where condensation won't form at the air outlet. In other words, when the difference in humidity value is greater than or equal to the first preset difference, the indoor humidity suddenly decreases, meaning the dehumidification mode can rapidly reduce indoor humidity. Switching the air conditioner 100 from anti-condensation mode to dehumidification mode allows it to quickly dehumidify the room, reaching a humidity level that prevents condensation at the air outlet more quickly, thus enabling the air conditioner 100 to enter normal operating mode sooner.

[0068] When the difference in the fourth humidity value is greater than or equal to the third preset difference, the air conditioner 100 uses the anti-condensation mode to ensure that the indoor air humidity has reached a level that will not cause condensation at the air outlet, thus causing the air conditioner 100 to directly exit the anti-condensation mode and enter the normal operation mode.

[0069] In some embodiments, such as Figure 5 As shown, the control method of the air conditioner 100 in this embodiment of the invention further includes the following steps:

[0070] S480: After the air conditioner 100 has been running in anti-condensation mode for a second preset period of time, control the air conditioner 100 to exit the anti-condensation mode.

[0071] In other words, after the air conditioner 100 has been running in anti-condensation mode for a long time, such as 700 minutes, the air conditioner 100 will be deactivated from the anti-condensation mode to ensure that the air conditioner 100 can operate normally.

[0072] In some embodiments, such as Figure 6 As shown, the control method of the air conditioner 100 in this embodiment of the invention further includes the following steps:

[0073] S404. After the air conditioner 100 exits the anti-condensation mode, determine whether the first humidity value is greater than or equal to the preset humidity value.

[0074] S405. If so, execute the control to run the air conditioner 100 in dehumidification mode.

[0075] In other words, after the air conditioner 100 exits the anti-condensation mode, the indoor humidity is monitored in real time. When the first humidity value is greater than the preset humidity value, the air conditioner 100 is controlled to enter the dehumidification mode. After entering the dehumidification mode, the operation described in the above embodiment is performed again. This ensures that condensate does not form at the air outlet of the air conditioner 100 during operation, thus further improving the anti-condensation effect of the control method of the air conditioner 100 in this embodiment.

[0076] In some embodiments, such as Figure 6 As shown, the control method of the air conditioner 100 in this embodiment of the invention further includes the following steps: after the air conditioner 100 has been turned on for a preset time, and when the first humidity value is greater than or equal to the preset humidity value, the air conditioner 100 is controlled to run in dehumidification mode. That is, after the air conditioner 100 has been turned on for a certain period of time, and the temperature and humidity changes in the indoor environment tend to stabilize, the humidity of the indoor environment is detected, thereby improving the accuracy of the detection.

[0077] In some embodiments, the control method of the air conditioner 100 of this embodiment of the invention can further detect whether the indoor temperature meets the requirements when determining whether the humidity of the indoor environment will cause condensation at the air outlet. For example, step S400 also includes the temperature value of the environment where the indoor unit of the air conditioner is located, and controls the air conditioner 100 to operate in anti-condensation mode according to the first humidity value, the second humidity value, and the temperature value. If the temperature value is less than 22 degrees Celsius, the anti-condensation mode or dehumidification mode is directly exited.
