[0045] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the control device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0046] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and an air conditioner windless dehumidification control program.

[0047] exist Figure 1In the control device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the control device of the present invention can be set in the control device, and the control device calls the air conditioner windless dehumidification control program stored in the memory 1005 through the processor 1001, and executes the air conditioner windless dehumidification control method provided by the embodiment of the present invention.

[0048] The embodiment of the present invention provides a method for controlling dehumidification of an air conditioner without wind sense, referring to Figure 2 , Figure 2 The figure is a flow chart of a first embodiment of a method for controlling windless dehumidification of an air conditioner according to the present invention.

[0049] The air conditioner windless dehumidification control method specifically comprises the following steps:

[0050] S10: receiving a windless dehumidification instruction;

[0051] A windless dehumidification mode has been added to the operating logic of the air conditioner. This mode is activated when a corresponding instruction is obtained. It should be understood that the instruction can be obtained by the user operating on the remote control or on the app of the mobile terminal. As long as a clear signal can be given, the activation of the corresponding mode can be triggered.

[0052] S20: After receiving the windless dehumidification instruction, controlling the air conditioner to start the windless dehumidification mode;

[0053] In response to receiving the windless dehumidification instruction, the air conditioner is controlled to start the windless dehumidification mode.

[0054] S30: In the windless dehumidification mode, the fan and the compressor of the air conditioner are controlled to operate, and the operating wind speed of the fan and the operating frequency of the compressor are limited according to the temperature parameter and the humidity parameter.

[0055] It should be understood that the principle of dehumidification is that the compressor works to cool, thereby reducing the outlet air temperature, and dehumidifying the room by blowing cold air, thereby reducing the humidity in the indoor environment, avoiding condensation, and thus reducing the user's perceived humidity. Therefore, in order to maintain the continuous operation of dehumidification, the compressor must still be in a working state, but considering the user's perceived temperature, the cooling effect on the indoor air is reduced by the fan's air volume and the compressor's operating frequency, thereby achieving a windless user experience.

[0056] In the windless dehumidification mode, the lowest working wind speed of the fan and the maximum operating frequency of the compressor are limited.

[0057] It should be noted that, in the structural design of the air conditioner, there is an air guide plate that can movably block the air outlet, and the air guide plate is provided with openings. For the adjustment of the wind speed, the degree of blocking of the air outlet by the air guide plate can be controlled to achieve a soft wind effect, and the air guide plate can even completely block the air outlet, so that only the openings on the air guide plate can outlet air to achieve a lower air volume. In the operation control of the air conditioner, different wind speed gears, i.e., wind gears, are designed according to different air output volumes. The wind gear can be adjusted to make the air guide plate automatically move to the specified position to control the air output.

[0058] In the technical solution of the present invention, a windless dehumidification operation mode is added, so that the wind speed of the air conditioner's fan and the frequency of the compressor can be controlled during dehumidification. By limiting the fan's lowest working wind speed and the compressor's maximum operating frequency, the air volume and cooling capacity of the air conditioner are kept in a lower operating state, thereby improving the user experience during the dehumidification process, reducing the wind sensation and the cold sensation. At the same time, the coordinated regulation of temperature parameters and humidity parameters is beneficial to optimizing the control range.

[0059] Considering the universal performance of the remote controller of the air conditioner, it is preferred to set the windless dehumidification mode in the corresponding model of the air conditioner, but the appearance and buttons of the remote controller are not adjusted to reduce the cost. At this time, in order to trigger the windless dehumidification mode, in some embodiments, in step S10:

[0060] After the air conditioner is turned on, if a dehumidification mode and a windless sense command are received from a user, it is determined that a windless sense dehumidification command is received.

[0061] That is, the windless dehumidification mode is triggered by the user operating two function buttons on the remote control in sequence. The user can input the corresponding mode instruction to the control device through the remote control by pressing the corresponding function button. The present invention does not limit the order in which the user presses the two function buttons. For example, the windless function can be turned on after the dehumidification mode is turned on, or the mode can be switched to the dehumidification mode after the windless function is turned on in the cooling mode. Both enable the control device to obtain the windless dehumidification instruction.

[0062] In other embodiments, in step S10:

[0063] S11: After the air conditioner is turned on, the historical mode when the air conditioner was last turned off is obtained;

[0064] That is, the air conditioner itself has a memory function. After a common air conditioner is turned on, it defaults to the mode last frozen before the last shutdown. Therefore, each time the air conditioner is turned on, the historical mode at the last shutdown is determined by obtaining the historical information stored in the memory.

[0065] S12: When the historical mode is the windless dehumidification mode, it is automatically determined as a windless dehumidification instruction after being turned on.

[0066] It should be understood that in this way of automatically controlling the air conditioner to enter the windless dehumidification mode through the memory mode, the user does not need to operate any function button on the remote controller. In order to facilitate the identification of the current operating state of the air conditioner, the symbol of the corresponding mode can be displayed on the display screen of the remote controller for the convenience of the user to judge, or the symbol of the corresponding mode can be added to the display screen of the air conditioner housing for the convenience of the user to judge.

[0067] It should be noted that when the air conditioner is turned on, the dehumidification mode was applied when it was shut down last time. At this time, the user only needs to input the windless sense command to control the air conditioner to start the windless dehumidification mode. However, considering the switching of different modes and avoiding operational errors, when the air conditioner is turned on, the cooling mode was applied when it was shut down last time. At this time, if the windless sense function has been turned on, if the user inputs the dehumidification command, the air conditioner should be controlled to only execute the dehumidification mode. Only when the windless sense command is input again can the windless dehumidification mode be entered. This is because a single function mode is mainly activated quickly by pressing a single function button. For a function mode like the windless dehumidification mode, it is preferentially read in the historical mode and implemented in cooperation with two or more function buttons, so as to avoid the situation where the user's operation is difficult and easy to cause functional debugging disorder.

[0068] In addition, you can use the app on the mobile terminal. After identifying the QR code information of the air conditioner or manually selecting the model of the air conditioner, the corresponding function interface will be updated to match the function mode of the air conditioner. For air conditioners with a windless dehumidification mode, a windless dehumidification mode option can be added to the operating interface of the app. In this way, users do not need to use the remote control to perform complicated operations, but can directly trigger the mode by clicking the corresponding option on the app.

[0069] Further, step S20 includes:

[0070] After receiving the windless dehumidification instruction, the fan and compressor of the air conditioner are controlled to work, and the air conditioner is controlled to run the conventional dehumidification mode to a set condition first, and then the air conditioner is controlled to start the windless dehumidification mode.

[0071] It should be understood that the principle of dehumidification mode is that the air conditioner operates through cooling, causing the moisture in the air to condense on the surface of the evaporator to reduce the air humidity. Limiting the wind speed of the fan and the cooling capacity of the compressor will affect the effect and efficiency of dehumidification. In the early stage of the air conditioner, the dehumidification effect of the room should be given priority to avoid condensation.

[0072] Specifically, the set condition can be a set running time, for example, the windless dehumidification mode is started after 20 minutes of conventional dehumidification mode; it can also be the humidity reaching the set humidity, for example, the conventional dehumidification mode reduces the indoor humidity from 90% to 709% and then the windless dehumidification mode is started; it can also be the temperature reaching the set temperature, for example, the conventional dehumidification mode reduces the indoor temperature from 27°C to 24°C and then the windless dehumidification mode is started.

[0073] The conventional dehumidification mode mentioned here is a frequency-limited method based on the GA algorithm. The GA algorithm is a frequency-limited method calculated according to temperature changes, and the calculation parameters involve indoor temperature and outdoor temperature.

[0074] It is understandable that when the set condition is the set running time, the present invention does not limit the specific value of the set running time, and needs to be reasonably designed according to the specific algorithm, that is, to ensure a certain dehumidification effect without allowing the indoor temperature to drop too quickly.

[0075] Further, step S30 includes:

[0076] S31: In the windless dehumidification mode, controlling the fan and compressor of the air conditioner to operate, and obtaining temperature parameters and humidity parameters;

[0077] It should be noted that the temperature parameter includes indoor temperature and outdoor temperature, and the humidity parameter includes indoor humidity. The humidity parameter is the indoor humidity.

[0078] S32: acquiring a limited wind speed of a fan and a limited frequency of a compressor according to the temperature parameter and the humidity parameter;

[0079] It should be understood that the calculation may be performed according to different algorithm logics, and may be based on the indoor and outdoor temperatures as calculation parameters, or may be based on the indoor humidity as calculation parameters.

[0080] S33: Controlling the fan to operate at a limited wind speed and the compressor to operate at a limited frequency, so as to limit the operating wind speed of the fan and the operating frequency of the compressor;

[0081] S34: re-obtaining the humidity parameter after every first set time, so as to obtain the current limiting wind speed of the fan according to the current humidity parameter;

[0082] It should be understood that during operation, the indoor humidity changes gradually. When the humidity is lower, the wind speed and frequency can be adjusted to a lower level. Therefore, a fixed cycle is set, and the indoor humidity is tested once after each first set time bmin to determine whether the current wind speed and frequency are appropriate, thereby forming a stable cycle control.

[0083] S35: Control the fan to operate according to the current limited wind speed.

[0084] For example, after the set running time of amin, the indoor humidity has decreased, and the indoor temperature has changed significantly. At this time, it is necessary to consider the cold feeling brought to the user by the dehumidification and cooling process. Therefore, control is performed according to the current indoor humidity to reduce the air volume and cooling capacity to ensure a better user experience.

[0085] Specifically, the wind speed is controlled by opening holes on the air guide strip, closing the large and small guides, adjusting the speed of the internal unit, etc. to reduce the user's feeling of being blown by wind. By designing the comparison relationship between the humidity wind gear and the comparison relationship between the wind gear and the compressor frequency, the wind gear of the fan and the frequency of the compressor are automatically adjusted based on the temperature change. In one embodiment, the comparison relationship table can be referred to Table 1 and Table 2.

[0086] Table 1 Humidity and wind speed comparison table

[0087]

[0088]

[0089] Table 2 Comparison table of wind speed and operating frequency

[0090] Windshield Maximum operating frequency (Hz) 80％-100％ Unlimited frequency 60％-80％ 62 40％-60％ 52 20％-40％ 42 1％-20％ Minimum dehumidification operating frequency

[0091] It should be understood that in Table 1, when the humidity range is above 80%, the air outlet of the air conditioner is not completely blocked by the air guide plate or the air guide strip, but retains a certain opening angle.

[0092] Furthermore, after step S20, the following steps are further included:

[0093] S40: obtaining temperature parameters during the operation of the air conditioner in the windless dehumidification mode;

[0094] It should be noted that the temperature parameters mentioned here mainly refer to indoor temperature.

[0095] S41: When the temperature parameter is lower than the first preset temperature, the air conditioner is controlled to switch from the windless dehumidification mode to the room temperature limited frequency mode.

[0096] Even if the wind speed and frequency are restricted, the indoor temperature will continue to drop during the dehumidification process. Moreover, since the humidity detection and the control of the wind speed frequency have a certain periodicity, the change range of the indoor temperature will also vary in different time periods. Moreover, when performing dehumidification control, although the user will input a set temperature through the remote control, the actual indoor temperature may gradually change to below the set temperature as the dehumidification progresses.

[0097] Therefore, based on these situations, the room temperature limiting mode is set, which is designed to control the indoor temperature and prevent the room temperature from being too low.

[0098] It should be noted that the first preset temperature is not the user's set temperature, but a protection value. If the user's set temperature is Tsc℃, the first preset temperature should be (Tsc-d)℃. If the current indoor temperature is lower than (Tsc-d)℃, the air conditioner is controlled to enter the room temperature limited frequency mode; if the temperature is greater than or equal to (Tsc-d)℃, the original operation state is continued.

[0099] Specifically, the control method of the room temperature frequency limiting mode is as follows:

[0100] S40A: In the room temperature frequency limiting mode, controlling the operating frequency of the compressor to reduce a set value, and controlling the electric auxiliary heating of the air conditioner to turn on;

[0101] It should be understood that the purpose of the room temperature frequency limiting mode is to restore the low temperature in the room. Therefore, the cooling capacity of the compressor needs to be reduced first. In the room temperature frequency limiting mode, the frequency of the compressor should be reduced by fHz compared to the minimum dehumidification frequency, and the corresponding wind speed will also be reduced. At the same time, the electric auxiliary heating is turned on, so that the indoor temperature rises, but the dehumidification function will not be completely turned off. Therefore, the current wind speed can be reduced, or it can remain consistent with the wind speed adjusted before entering the room temperature frequency limiting mode in the windless dehumidification mode.

[0102] S40B: reacquiring the temperature parameter after the air conditioner runs for a second set time;

[0103] It should be noted that the cycle period is also set in the room temperature frequency limiting mode, that is, the second set time cmin, and the second set time can be the same as or different from the first set time. It needs to be reasonably designed according to the power of the electric auxiliary heating, and it is preferred to set the second set time to be less than the first set time. For example, when b=20min, set c=10min.

[0104] S40C: If the current temperature parameter reaches the preset temperature recovery condition, the electric auxiliary heating of the air conditioner is controlled to be turned off, and the air conditioner is controlled to switch from the room temperature frequency limiting mode to the windless dehumidification mode.

[0105] It should be understood that the temperature recovery preset condition may not be the same as the value of the first preset temperature, which takes into account the fluidity of the air and the diffusion of the temperature. For example, after entering the room temperature frequency limiting mode, the indoor temperature is detected and determined once every cmin. If the room temperature rises and is higher than (Tsc-e)℃, the room temperature frequency limiting mode is exited and the process returns to step S30. Otherwise, the room temperature frequency limiting mode is continued and the electric auxiliary heating continues to heat.

[0106] It should be noted that it is preferred to set the value e to be smaller than the value d. For example, when d=4min, e=3min is designed.

[0107] Furthermore, in one embodiment, the set running time can execute only the conventional dehumidification mode. After the set running time ends, the windless dehumidification mode is started, but at the same time the algorithm logic corresponding to the conventional dehumidification mode does not stop. Specifically, after the set running time, the frequency value of the maximum operating frequency of the air conditioner in the conventional dehumidification mode is calculated according to the indoor temperature and the outdoor temperature, and the frequency value of the maximum operating frequency of the air conditioner in the windless dehumidification mode is calculated according to the indoor humidity. The two frequency values ​​are compared to take the operating mode corresponding to the lower frequency value as the target operating mode, and the air conditioner is controlled to operate in the target operating mode.

[0108] It should be understood that such a setting can optimize the frequency control range. The algorithm logic corresponding to the two working modes is different, and the calculation parameters are also different. Therefore, different frequency values ​​as limits can be calculated. In order to reduce the user's feeling of coldness, it is preferred that under the current working conditions, the working mode that can be controlled with a lower frequency value is run as the target working mode.

[0109] Under different temperature and humidity environments, the target working mode can be a conventional dehumidification mode or a windless dehumidification mode. It should be understood that, in general, the windless dehumidification mode has a lower control frequency limit.

[0110] In addition, after the air conditioner starts the windless dehumidification mode, the wind speed and frequency can be automatically adjusted based on the above control logic, or manually adjusted by the user, that is, after step S10, the following is also included:

[0111] S20': receiving a wind speed control instruction inputted by a user, and limiting the maximum operating frequency of the compressor of the air conditioner according to the wind speed control instruction.

[0112] At this time, the wind speed control is no longer associated with the humidity, but is mainly regulated by the user. According to the wind speed limit, the operating frequency of the compressor is also adjusted adaptively according to Table 2.

[0113] During the operation of step S20, even if the temperature set by the user is met, the air conditioner does not automatically end the dehumidification mode, but usually runs at the lowest dehumidification frequency, and there is still a continuous cooling phenomenon. Considering the comfort level of the indoor temperature, a temperature-reaching shutdown mechanism is set, specifically:

[0114] S201: When the air conditioner is operating in a windless dehumidification mode, obtaining an actual indoor temperature;

[0115] It should be noted that the acquisition of the actual indoor temperature can be added in the whole process, that is, the actual indoor temperature detection is independent of the room temperature detection in step S40, or the temperature parameter of step S40 can be directly used as the actual indoor temperature, on the one hand to evaluate whether it is necessary to start the room temperature frequency limiting mode, and on the other hand to evaluate whether it is necessary to control the compressor to stop.

[0116] S202: If the actual indoor temperature is lower than the second preset temperature, control the compressor of the air conditioner to stop running;

[0117] It should be noted that after the compressor is turned off and the remaining cold capacity is discharged, the air conditioner functions as a fan and only blows air without cooling. The second preset temperature should be lower than the user's set temperature.

[0118] S203: re-obtaining the actual indoor temperature after every third set time;

[0119] It should be understood that after stopping cooling, it takes a certain amount of time for the indoor temperature to rise back to normal, and the speed of the rise is also affected by the outdoor ambient temperature.

[0120] S204: If the current actual indoor temperature rises back to the third preset temperature, control the compressor of the air conditioner to restart.

[0121] It should be noted that the third preset temperature is greater than the second preset temperature.

[0122] For example, during the windless dehumidification process, if the room temperature drops below (Tsc-6)℃, the compressor stops running; when the room temperature rises above (Tsc-4)℃, the temperature shutdown function is released and the compressor restarts.

[0123] The setting of each parameter value needs to be determined based on experiments. In one embodiment, the setting parameters are a=20, b=20, c=10, d=4, e=3, f=4, please refer to the attached Figure 2 , the operation process of the air conditioner is as follows:

[0124] 1. After the air conditioner is turned on, it can be switched to windless dehumidification mode in the following situations:

[0125] After turning on the dehumidification mode, turn on the windless function;

[0126] After the cooling mode windless function is turned on, the mode is converted to dehumidification mode;

[0127] The remote control remains in the windless dehumidification mode and then turns on.

[0128] 2. In the first 20 minutes of operation, only the conventional dehumidification mode is executed, and the minimum working wind speed and maximum operating frequency of the air conditioner are limited according to the changes in indoor and outdoor temperatures; after running for 20 minutes, the windless dehumidification mode is turned on, and the cycle detection mode is entered at the same time. The humidity will be detected every 20 minutes of operation, and the minimum operating wind speed will be automatically limited. Manual adjustment of the wind speed by the user is effective during the operation.

[0129] 3. During the humidity cycle detection, the indoor temperature will also be checked. If the temperature is lower than (Tsc-4)℃, the room temperature frequency limiting mode will be entered; if the temperature is greater than or equal to (Tsc-4)℃, the above operation status will continue.

[0130] After entering the room temperature frequency limiting mode, the frequency drops by 4Hz compared to the minimum dehumidification frequency, and the electric auxiliary heating is turned on. A judgment is made on one side every 10 minutes. If the room temperature rises and is higher than (Tsc-3)℃, the room temperature frequency limiting mode is exited, otherwise the room temperature frequency limiting mode continues to operate.
