For those skilled in the art, the specific meaning of the above terms in the present embodiments can be understood according to the specific circumstances.

[0032] Figures 1 to 7 The control method of the air conditioner, the control device of the air conditioner and the air conditioner provided by the present application are shown. As can be seen from the drawings, the control method of the air conditioner of the present application comprises:

[0033] S110: obtaining the instantaneous inlet air temperature and the preset dew point temperature in the cooling mode.

[0034] In the embodiments of the present application, before the step of obtaining the instantaneous inlet air temperature and the preset dew point temperature in the cooling mode, specifically, it can include: in response to the running signal of the cooling mode, determining the running time length of the cooling mode to the preset time length; obtaining the instantaneous inlet air temperature and the preset dew point temperature.

[0035] In a specific implementation, after the air conditioner enters the cooling mode and runs for a predetermined time length, the instantaneous inlet air temperature of the air conditioner can be detected by the temperature sensor, so as to obtain the instantaneous inlet air temperature and the preset dew point temperature. That is, after the air conditioner is started to cool, the air conditioner is first run for a predetermined time length, for example, one hour, and then the corresponding step of reducing the condensate dripping is performed after the user's temperature demand is met.

[0036] S120: generating a control strategy (or referred to as a first control strategy) according to the instantaneous inlet air temperature and the preset dew point temperature.

[0037] S130: controlling the operation of the air conditioner according to the control strategy.

[0038] The air conditioner control method, air conditioner control device and air conditioner provided by the application can generate a control strategy according to the instantaneous inlet air temperature and the preset dew point temperature in the cooling mode, so as to control the operation of the air conditioner according to the control strategy. Therefore, the air at the position of the air deflector is less likely to reach the dew point temperature, the user's experience is improved, and the technical problem that the air deflector is located at the cold-heat intersection of air in the cooling mode of the air conditioner in the prior art, so that condensate is easily formed and drips.

[0039] As shown in FIG. 1, in one possible implementation, the step of S120: generating a control strategy according to the instantaneous inlet air temperature and the preset dew point temperature can specifically include: Figure 2 S121: determining that the instantaneous inlet air temperature is less than the preset dew point temperature.

[0040] S122: controlling the indoor fan to increase to a preset indoor unit rotating speed at a preset wind speed level, wherein the preset wind speed level is a rotating speed increase level of the indoor fan per unit time.

[0041] In a specific implementation, for example, the indoor unit rotating speed is increased by 100 revolutions per minute. By increasing the preset indoor unit rotating speed, the aggregation of the wet air at the air deflector can be reduced, which is equivalent to reducing the humidity. Therefore, the air at the position of the air deflector is less likely to reach the dew point temperature, so that the condensate is less likely to be formed.

[0042] As shown in FIG. 1, in the embodiment of the application, the step of S122: controlling the indoor fan to increase to a preset indoor unit rotating speed at a preset wind speed level can specifically include:

[0043] Figure 3 S1221: obtaining an outlet opening degree value of an outlet opening of the air conditioner.

[0044] S1222: determining that the outlet opening degree value is less than a preset opening degree threshold.

[0045] ​In the embodiment of the present application, the output shaft of the air deflector driving motor is connected to the air deflector to drive the air deflector to change the position of the air deflector, thereby changing the opening degree of the air outlet. Therefore, the position of the air deflector can be determined by determining the rotation angle of the output shaft of the air deflector driving motor, and the opening degree of the air outlet of the air conditioner can be determined by determining the position of the air deflector.

[0046] S1222: determining the preset indoor unit rotation speed according to the air outlet opening degree value.

[0047] In the embodiment of the present application, the air outlet can have four air outlet opening degree values in turn decreasing, and the indoor fan can have four preset indoor unit rotation speeds in turn increasing and corresponding to the four air outlet opening degree values. The four air outlet opening degree values can be a first air outlet opening degree value, a second air outlet opening degree value, a third air outlet opening degree value, and a fourth air outlet opening degree value, the first air outlet opening degree value being the largest and the fourth air outlet opening degree value being the smallest, and the four preset indoor unit rotation speeds can be a first preset indoor unit rotation speed, a second preset indoor unit rotation speed, a third preset indoor unit rotation speed, and a fourth preset indoor unit rotation speed, the first preset indoor unit rotation speed being the smallest and the fourth preset indoor unit rotation speed being the largest. The preset indoor unit rotation speed can be determined according to the difficulty of dew point. That is, the preset indoor unit rotation speed can be set as the rotation speed of the indoor fan that is not easy to condense. For example, the first preset indoor unit rotation speed can be 600 revolutions per minute, the second preset indoor unit rotation speed can be 700 revolutions per minute, the third preset indoor unit rotation speed can be 800 revolutions per minute, and the fourth preset indoor unit rotation speed can be 900 revolutions per minute.

[0048] In specific implementation, if the obtained air outlet opening degree value of the air outlet of the air conditioner is the first air outlet opening degree value, since the first air outlet opening degree value corresponds to the first preset indoor unit rotation speed, the preset indoor unit rotation speed can be determined as the first preset indoor unit rotation speed, i.e., 600 revolutions per minute, according to the air outlet opening degree value.

[0049] As shown in FIG. 1, in another possible embodiment, S120: generating a control strategy according to the instant inlet air temperature and the preset dew point temperature, can specifically include: Figure 4

[0050] S123: determining that the instant inlet air temperature is less than the preset dew point temperature.

[0051] S124: obtaining the instant indoor unit rotation speed of the indoor fan.

[0052] S125: determining that the instant indoor unit rotation speed is greater than the preset indoor unit rotation speed, and then adjusting the instant operation frequency of the compressor to the preset operation frequency.

[0053] In the embodiment of the present application, the instant operation frequency can be controlled to decrease to the preset operation frequency by a preset frequency magnitude, where the preset frequency magnitude is the frequency reduction magnitude of the compressor per unit time. For example, the frequency is reduced by 5 hertz per minute.​

[0054] In actual implementation, since the compressor frequency reduction affects the refrigerating capacity of the air conditioner, the indoor temperature fluctuation can be reduced, and the user's normal use experience of the air conditioner can be prevented from being affected due to the solution to the condensate water problem.

[0055] According to an embodiment of the present application, the step of controlling the instant operation frequency to reduce to the preset operation frequency in the preset frequency magnitude can specifically include: obtaining an outlet opening degree value of an outlet opening of the air conditioner; and determining the preset operation frequency according to the outlet opening degree value.

[0056] In actual implementation, the outlet opening can have four outlet opening degree values that are sequentially reduced, and the indoor fan can have four preset operation frequencies that are sequentially reduced and correspond to the four outlet opening degree values one by one. The four outlet opening degree values can be a first outlet opening degree value, a second outlet opening degree value, a third outlet opening degree value, and a fourth outlet opening degree value, the first outlet opening degree value being the largest and the fourth outlet opening degree value being the smallest. The four preset operation frequencies can be a first preset operation frequency, a second preset operation frequency, a third preset operation frequency, and a fourth preset operation frequency, the first preset operation frequency being the largest and the fourth preset operation frequency being the smallest. The preset operation frequency can be determined according to the difficulty of the dew point. That is, the preset operation frequency can be set to the compressor frequency that is not easy to condense. For example, the first preset operation frequency can be 50 Hz, the second preset operation frequency can be 40 Hz, the third preset operation frequency can be 30 Hz, and the fourth preset operation frequency can be 20 Hz. If the obtained outlet opening degree value of the outlet opening of the air conditioner is the first outlet opening degree value, since the first outlet opening degree value corresponds to the first preset operation frequency, the preset operation frequency can be determined to be the first preset operation frequency, i.e., 50 Hz, according to the outlet opening degree value.

[0057] It can be understood that the air speed of the air conditioner is generally related to the rotation speed of the indoor fan, that is, the higher the rotation speed of the indoor fan, the greater the air speed of the air conditioner. When the user adjusts the air speed of the air conditioner through the air conditioner control device such as a remote controller, if the air speed is increased, the instant indoor fan rotation speed is increased. For example, if the user adjusts the air speed so that the instant indoor fan rotation speed is 1000 revolutions per minute, the instant operation frequency of the compressor is adjusted to the preset operation frequency. The frequency of the compressor is adjusted to adjust the refrigerating capacity of the air conditioner, and then the temperature at the position of the deflector is adjusted, so that the air at the position of the deflector is not easy to reach the dew point temperature, and the user's use experience is further improved. The technical problem that the condensate water drops due to the fact that the position of the deflector is at the cold and hot intersection of the air in the refrigerating mode of the air conditioner in the prior art is solved.

[0058] As Figure 5As shown, in still another possible implementation, the step S120 of generating the control strategy according to the instant inlet air temperature and the preset dew point temperature can specifically include:

[0059] S126: determining that the instant inlet air temperature is less than the preset dew point temperature.

[0060] S127: controlling the indoor fan to increase to the preset indoor machine rotating speed at the preset wind speed level, and adjusting the instant operating frequency of the compressor to the preset operating frequency, wherein the preset wind speed level is the rotating speed increase level of the indoor fan per unit time.

[0061] That is, the priority of the speed adjustment is higher than that of the frequency adjustment. For example, if the instant inlet air temperature is less than the preset dew point temperature, the indoor fan is first controlled to increase to the preset indoor machine rotating speed at the preset wind speed level, and then the instant operating frequency of the compressor is adjusted to the preset operating frequency when the instant indoor machine rotating speed is equal to the preset indoor machine rotating speed.

[0062] In particular implementation, through the above setting, the deflector position is less likely to generate condensate water through the speed adjustment, and the deflector position is less likely to generate condensate water without affecting the refrigeration capacity. If condensate water is still generated after the speed adjustment, the frequency adjustment is further performed to further make the deflector position less likely to generate condensate water.

[0063] It can be understood that, since the frequency adjustment will affect the refrigeration capacity of the air conditioner to a certain extent, the priority of the speed adjustment is higher than that of the frequency adjustment, so as to improve the user experience.

[0064] In summary, the air conditioner and the control method thereof can adjust the rotating speed of the indoor fan and the frequency of the compressor without changing the outlet air angle (the opening degree of the outlet) and without interfering with the user's demand for the outlet air angle, so as to improve the condensation of the air conditioner.

[0065] In some embodiments, the control method of the air conditioner includes: obtaining the working mode of the air conditioner and the indoor environment temperature; determining that the working mode is a cooling mode or a heating mode, and generating a control strategy (or referred to as a second control strategy) according to the temperature difference between the set temperature corresponding to the working mode and the indoor environment temperature; and controlling the deflector at the outlet of the air conditioner according to the control strategy to adjust the area of the outlet, wherein the temperature difference is negatively correlated with the area of the outlet.

[0066] In specific implementation, if the working mode is the cooling mode or the heating mode, a control strategy is generated according to the temperature difference between the set temperature corresponding to the working mode and the indoor environment temperature, and then the air deflector at the air outlet of the air conditioner is controlled according to the control strategy to adjust the area of the air outlet. The temperature difference is negatively related to the area of the air outlet. Taking the cooling mode as an example, when the air conditioner is just started, the temperature difference is large, and the area of the air outlet can be reduced by controlling the air conditioner to increase the wind power, so as to timely meet the temperature demand of the user and timely relieve the hot feeling of the user. With the operation of the air conditioner, the temperature difference gradually decreases, and the area of the air outlet can be increased by controlling the air conditioner to reduce the wind power, so as to prevent the user from feeling too low in temperature after adapting to the current indoor environment temperature, improve the comfort of the user, improve the use experience, and solve the technical problems in the prior art that the air conditioner cannot timely meet the temperature demand of the user when it is just started, and the user feels uncomfortable due to the too large airflow when the temperature difference between the set temperature and the indoor environment temperature gradually decreases.

[0067] According to an embodiment of the present application, the step of generating a control strategy according to the temperature difference between the set temperature corresponding to the working mode and the indoor environment temperature can specifically include: determining that the absolute value of the temperature difference is greater than a preset value, adjusting the air outlet to a first air outlet area; determining that the absolute value of the temperature difference is less than the preset value and greater than zero, adjusting the air outlet to a second air outlet area; and determining that the temperature difference is equal to zero, adjusting the air outlet to a third air outlet area. The first air outlet area is smaller than the second air outlet area, and the second air outlet area is smaller than the third air outlet area.

[0068] In specific implementation, if the absolute value of the temperature difference is greater than the preset value, the air outlet is adjusted to the first air outlet area; if the absolute value of the temperature difference is less than the preset value and greater than zero, the air outlet is adjusted to the second air outlet area; and if the temperature difference is equal to zero, the air outlet is adjusted to the third air outlet area. That is, the greater the absolute value of the temperature difference, the smaller the area of the air outlet.

[0069] According to an embodiment of the present application, the step of determining that the temperature difference is equal to zero and adjusting the air outlet to the third air outlet area can specifically include: adjusting the orientation of the air deflector in response to a temperature difference signal that the temperature difference is equal to zero, so that the air outlet faces the roof of the room.

[0070] In specific implementation, taking the cooling mode as an example, when the air outlet faces the roof of the room, the cold air blows to the roof, and then the cold air gradually falls. Thus, not only can the user be prevented from feeling uncomfortable due to the direct blowing of the airflow from the air outlet, but also, since the hot air in the air is generally in the upper layer, when the cold air reaches the roof, the cold air exchanges heat with the hot air in the upper layer of the indoor environment first, then increases the temperature of the cold air, so that the falling cold air is not too low in temperature, and thus the user does not feel too cold and other discomforts when contacting the user, further improving the comfort of the user.
