Referring to fig. 1, fig. 1 is a schematic flow chart of an anti-condensation control method according to an embodiment of the present invention;
the method is applied to an air conditioner indoor unit with double air deflectors, the air conditioner indoor unit comprises a first air deflector and a second air deflector, and the anti-condensation control method comprises the steps of S101-S107.
S101, when a refrigeration mode is started or the second air deflector exits from the anti-condensation angle;
s102, acquiring a current wind guide angle of a first wind guide plate, and recording the running time;
the first air deflector can set a plurality of different air deflection angles to provide different refrigeration modes;
s103, determining preset time corresponding to the current air guide angle of the first air guide plate according to the preset corresponding relation;
different preset times corresponding to different wind guide angles of the first wind guide plate are set;
s104, judging whether the current running time reaches the corresponding preset time and whether the current environment humidity of the indoor unit reaches a first preset humidity value, if so, entering a step S105, and if not, returning to the step S102;
if the current operation time does not reach the corresponding preset time or the current environment humidity of the indoor unit (specifically, the internal environment humidity of the indoor unit, or the environment humidity of the external air outlet region) does not reach the first preset humidity value, the step S102 needs to be returned to obtain the current air guide angle of the first air guide plate again, and the current operation time is continuously recorded;
s105, controlling the second air deflector to be opened to a corresponding condensation-preventing angle;
the different air guide angles of the first air guide plate correspond to the different condensation preventing angles of the second air guide plate;
in steps S101 to S105, a first preset humidity value and a corresponding preset time are set for different air guiding angles of the first air guiding plate to perform monitoring, so as to control the second air guiding plate to open to a corresponding anti-condensation angle at a suitable node to perform air supply and refrigeration in cooperation with the corresponding anti-condensation angle.
Further, after step S105, the method further includes:
s106, judging whether the time length for keeping the current condensation-preventing angle of the second air deflector reaches a set time length, and/or judging whether the current environment humidity of the indoor unit reaches a second preset humidity value, if so, entering the step S107, otherwise, re-judging until entering the step S107;
preferably, when the set time length is reached or a second preset humidity value is reached, the step S107 is executed;
and S107, controlling the second air deflector to exit the condensation-preventing angle.
The second air deflector is controlled to exit the anti-condensation angle, namely the second air deflector is controlled to be closed to a closed state, the running time of the first air deflector and the time length of the second air deflector for keeping the anti-condensation angle are reset, and then the next round of timing is carried out.
In steps S106 to S107, after the second air deflector is controlled to be opened to the corresponding anti-condensation angle, monitoring is performed according to the set time and the second preset humidity value, so as to control the second air deflector to be closed at a suitable node and exit the anti-condensation angle.
According to the invention, the problems of condensation on the outer edge of the second air deflector and condensation on the outer wall surface of the first air deflector are effectively solved by the air supply mode of matching the first air deflector with the second air deflector; meanwhile, under the condition that the refrigeration mode is ensured not to blow people, the rotating speed of the indoor unit of the air conditioner and the frequency of the outdoor unit are not changed, and the comfort experience of users is improved.
In an embodiment, the air guiding angle of the first air guiding plate is negatively correlated with the corresponding preset time, and the air guiding angle of the first air guiding plate is an included angle formed by the first air guiding plate and the indoor unit panel.
In this embodiment, an included angle formed by the first air deflector and the indoor unit panel is set to θ, and when the air conditioner is turned on, the first air deflector is firstly opened to a default angle set to θ m The user can set different cooling modes (i.e. change the wind guiding angle of the first wind guiding plate) by the remote control device, and the default position (theta) is used in the embodiment m ) Stop position 1(θ) 1 ) Stop position 2(θ) 2 ) And freeze position 3(θ) 3 ) These four angles are taken as an example, and θ is set 3 ＞θ 2 ＞θ m ＞θ 1 (ii) a According to the condensation experimental phenomenon, the smaller the wind guide angle of the first wind deflector, the easier the condensation, the faster the current environment humidity of the indoor unit rises, so that the corresponding preset time is relatively shorter so as to trigger the second wind deflector to open to the condensation-preventing angle relatively earlier, and based on the preset time, four preset times corresponding to the four angles can be set, namely: t is 1 Corresponds to theta 1 ，T m Corresponds to theta m ，T 2 Corresponds to theta 2 ，θ 3 Corresponds to T 3 And T is 3 ＞T 2 ＞T m ＞T 1 。
Therefore, the judgment in step S104 is to determine whether the current operation time reaches the corresponding preset time, that is: judging whether the operation time of the first air deflector at the current air guiding angle reaches the corresponding preset time at the current air guiding angle, for example, judging whether the operation time of the first air deflector at the current air guiding angle theta 1 Whether the running time of the system reaches the preset time T or not 1 . Meanwhile, whether the current environment humidity of the indoor unit reaches a first preset humidity value or not is judged in a matched mode, so that the second air deflector is controlled to be opened to a corresponding anti-condensation angle at a proper node.
In an embodiment, the anti-condensation angle of the second air guiding plate is negatively correlated with the air guiding angle of the first air guiding plate, and the anti-condensation angle of the second air guiding plate is an included angle between the anti-condensation state and the closed state of the second air guiding plate.
In this embodiment, the anti-condensation angle of the second air guiding plate depends on the air guiding angle of the first air guiding plate, and taking the four set air guiding angles of the first air guiding plate as an example, the second air guiding plate can set four anti-condensation angles corresponding to the four angles, that is: phi 1 Corresponds to theta 1 ，Φ m Corresponds to theta m 、Φ 2 Corresponds to theta 2 ，Φ 3 Corresponds to T 3 Similarly, the condensation experiment phenomenon that condensation is more likely to occur as the wind guide angle of the first wind guide plate is smaller can be used to obtain phi 3 ＞Φ 2 ＞Φ m ＞Φ 1 . It can be understood that: when the first air deflector is at the air deflection angle theta 1 The running time of the system reaches the preset time T 1 When the current environment humidity of the indoor unit does not reach a first preset humidity value, the second air deflector can be controlled to be opened to an anti-condensation angle phi 1 。
It should be noted that, of the air guiding angle of the first air guiding plate and the condensation preventing angle of the second air guiding plate, the angles are not limited to the four corresponding angles, and more angles are also applicable to the present invention.
In one embodiment, as shown in fig. 2, step S103 includes:
s201, obtaining current running time;
s202, judging whether the current running time reaches the corresponding preset time, if not, entering the step S203, and if so, returning to the step S104 to further judge whether the current environmental humidity of the indoor unit reaches a first preset humidity value;
s203, judging whether the current air guide angle of the first air guide plate changes, if so, entering a step S204, and if not, returning to the step S201;
s204, comparing the wind guide angle before the change with the wind guide angle after the change; determining a smaller wind guide angle;
and S205, according to the preset corresponding relation, taking the preset time corresponding to the smaller wind guide angle as the corresponding preset time for newly judging the current running time.
In the operation process of the indoor unit, the corresponding preset time is determined in real time according to the current air guide angle of the first air guide plate, because in the operation process of the indoor unit, a user can adjust different 'refrigeration' modes, that is, the air guide angle of the first air guide plate can be changed, and at this time, the corresponding preset time needs to be adjusted correspondingly.
In a specific scenario, the four wind guiding angles of the first wind guiding plate are set as follows, for example: when the wind guide angle of the first wind guide plate is theta m And at the wind guiding angle theta m The current running time of the system does not reach the preset time T m When the wind guide angle theta of the first wind guide plate is judged m Changed to wind guide angle theta 1 At this time, the wind guiding angle θ needs to be compared m And wind guiding angle theta 1 Is given by the magnitude of (1), θ m ＞θ 1 Therefore, a smaller wind guiding angle θ is required 1 Corresponding preset time T 1 As a new corresponding preset time for determining the current operating time. Furthermore, for example, the first wind deflector is arranged from a wind deflecting angle theta m Changed to wind guide angle theta 2 Let us know θ 2 ＞θ m At this time, the wind guide angle θ is small m Corresponding preset time T m Is still usedAnd judging the corresponding preset time of the current running time.
