Fig. 4 schematically shows a flowchart of a method for controlling a tower cooling fan according to an embodiment of the present invention. As can be seen from fig. 4, a method for controlling a tower-type cooling fan includes the following steps:
s1, acquiring a humidity value of a wet curtain 7 of a tower type cooling fan;
in the embodiment of the invention, the humidity of the wet curtain 7 is detected in real time by the humidity detectors 1-3 mounted on the wet curtain to judge whether the wet curtain 7 is in a dry state or in a wet state.
S2, controlling the working state of an air deflector 1-1 in the tower type cooling fan according to the humidity value so as to adjust the evaporation area of a wet curtain 7 relative to the fan blades 5, wherein the air deflector 1-1 is arranged between the wet curtain 7 and the fan blades 5.
In the embodiment of the invention, the cold fan is started, the wet curtain 7 is in a dry state, and the wet curtain takes a certain time to absorb water, so that water drops which are not absorbed by the wet curtain are blown out after the fan blades 5 are started, namely the water splashing condition occurs, and therefore, whether the current wet curtain absorbs sufficient water or not is judged by judging the humidity condition of the wet curtain 7, and further, whether the water splashing phenomenon exists or not is judged.
In the embodiment of the present invention, the controlling the working state of the air deflector in the tower-type cooling fan according to the humidity value specifically includes the following steps, which are not shown in the attached drawings:
s11, judging whether the humidity value is smaller than a preset first humidity threshold value or not;
s12, if the humidity value is smaller than the first humidity threshold value, controlling the air deflector 1-1 to be closed.
In the embodiment of the invention, the first humidity threshold is a humidity threshold determined through experiments, and the first humidity threshold is different for different types of air coolers and wet curtains. And when the humidity value is smaller than the first humidity threshold value, the current wet curtain is proved to be in a relatively dry state, and if the condition of flying water exists, the air deflector 1-1 is controlled to be closed.
Preferably, in the embodiment of the present invention, when it is determined that the humidity value is smaller than the first humidity threshold, the method for controlling the tower-type cooling fan further includes determining whether the air deflector 1-1 is closed, and if the air deflector 1-1 is closed, the closing of the air deflector does not need to be controlled, and the subsequent steps of the method for controlling the tower-type cooling fan are executed. If the air deflector 1-1 is not closed, the step S12 is executed.
Further, because the concrete structure of the tower-type cooling fan according to the embodiment of the present invention is that the covering area when the air deflector 1-1 is closed is the same as the projection area of the wet curtain 7 and is smaller than the area of the air inlet 3, a large gap is formed between the air inlet 3 and the wet curtain component, even if the air deflector 1-1 is completely closed, the airflow enters from the air inlet 3 and then exits through the gaps at both sides, so the air deflector 1-1 does not obstruct the air outlet and air outlet directions of the air outlet 4 of the front case when closed, but the air outlet amount is reduced, and in order not to affect the user experience, after the air deflector 1-1 is controlled to be closed, the air-water compensation needs to be performed on the fan, and the concrete compensation method is as follows:
s13, acquiring a current wind speed gear of the tower type cooling fan;
s14, acquiring air inlet compensation quantity corresponding to a current wind speed gear according to the current wind speed gear;
s15, adjusting the rotating speed of the fan blade 5 according to the air inlet compensation quantity.
Further, the air inlet compensation quantity and the type of the cooling fan, the shielding area, the proportion occupied by the shielding area and the air inlet area and the like are all related, and the specific compensation quantity is pre-stored in the system through calculation and test correction.
Furthermore, the humidity detector 1-3 of the embodiment of the invention can not only detect the humidity and judge whether the possibility of water flying exists, but also judge whether the current water tank is lack of water. The specific judgment method comprises the steps of timing the closing time of the air deflector 1-1; and when the closing time of the air deflector 1-1 reaches a preset water shortage time threshold value, sending a water shortage alarm prompt.
Further, the embodiment of the present invention further includes determining whether the humidity value is greater than or equal to a preset second humidity threshold, and when it is detected that the humidity value of the wet curtain 7 is greater than or equal to the preset second humidity threshold, the embodiment of the present invention further includes the following steps that are not shown in the attached drawings:
s21, if the humidity value is larger than or equal to the second humidity threshold value, timing the duration time of the humidity value larger than or equal to the second humidity threshold value;
s22, when the duration time is longer than a preset humidity time threshold value, controlling the air deflector 1-1 to be opened.
In the embodiment of the invention, when the humidity value is detected to be greater than or equal to the second humidity threshold value, a certain safety time needs to be reserved for further ensuring that no water splashing phenomenon occurs, timing is started after the humidity value is detected to be greater than or equal to the second humidity threshold value, and when the timing reaches the humidity time threshold value, the air deflector 1-1 is controlled to be started.
The second humidity threshold value in the embodiment of the present invention may be the same as or different from the first humidity threshold value. Specific settings are determined by experiments for different models.
Preferably, in the embodiment of the present invention, when it is determined that the humidity value is greater than or equal to the second humidity threshold, the method for controlling a tower-type cooling fan further includes determining whether the air deflector 1-1 is closed, and if the air deflector 1-1 is not closed, the method does not need to be controlled to be opened again, and then the subsequent steps of the method for controlling a tower-type cooling fan are executed. If the air deflector 1-1 is closed, the step S21 is executed.
Further, the control method of the cooling fan in the embodiment of the invention further comprises the step of adjusting the evaporation area of the wet curtain 7 relative to the fan blades 5 by adjusting the opening and closing angle of the air guide plate 1-1, so as to adjust the evaporation capacity and further adjust the ambient temperature and humidity. The specific control method comprises the steps of obtaining a temperature control gear selected by a user; and adjusting the opening and closing angle of the air deflector 1-1 according to the temperature control gear selected by the user.
Further, the user selected temperature control gear includes the user's requirements for temperature and humidity.
