Referring to fig. 1, fig. 1 is a schematic flow chart of an anti-condensation control method according to an embodiment of the 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 steps S101-S107.
S101, when a refrigeration mode is started or the second air deflector exits the condensation preventing angle;
s102, acquiring the current air guide angle of the first air guide plate, and recording the running time;
the first air deflector can set a plurality of different air guiding 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 a preset corresponding relation;
wherein, different preset times corresponding to different air guide angles of the first air guide plate;
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;
the current operation time does not reach the corresponding preset time, or the current environmental humidity of the indoor unit (specifically, the internal environmental humidity of the indoor unit or the environmental humidity of the external air outlet area) does not reach the first preset humidity value, the step S102 is required to be returned to acquire the current air guiding angle of the first air guiding plate again, and the current operation time is continuously recorded;
s105, controlling the second air deflector to be opened to a corresponding anti-condensation angle;
wherein, different air guide angles of the first air guide plate correspond to different condensation prevention angles of the second air guide plate;
in steps S101-S105, for different air guide angles of the first air guide plate, a first preset humidity value and a corresponding preset time are set for monitoring, so as to control the second air guide plate to open to a corresponding anti-condensation angle at a proper node for matching air supply and refrigeration.
Further, after step S105, the method further includes:
s106, judging whether the duration of the second air deflector for keeping the current anti-condensation angle reaches a set duration and/or judging whether the current environmental humidity of the indoor unit reaches a second preset humidity value, if so, entering a step S107, otherwise, judging again until entering the step S107;
preferably, when the set duration is reached or the second preset humidity value is reached, step S107 is entered;
s107, controlling the second air deflector to withdraw from the condensation preventing angle.
The second air guide plate is controlled to exit the condensation preventing angle, namely, after the second air guide plate is controlled to be closed to be in a closed state, the running time of the first air guide plate and the duration of the second air guide plate for keeping the condensation preventing angle are cleared, and then the next round of timing is performed.
In the steps S106-S107, after the second air deflector is controlled to be opened to the corresponding anti-condensation angle, monitoring is carried out according to the set time length and the second preset humidity value so as to control the second air deflector to be closed and withdraw from the anti-condensation angle at a proper node.
According to the invention, the problem of condensation on the outer edge of the second air deflector and the problem of condensation on the outer wall surface of the first air deflector are effectively solved by adopting a mode of matching the first air deflector with the second air deflector for air supply; meanwhile, under the condition that people are not blown in the refrigeration mode, the mode of rotating speed of the indoor unit and frequency of the outdoor unit of the air conditioner is not changed, and comfort experience of a user is improved.
In an embodiment, the air guiding angle of the first air guiding plate is inversely related to 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, the included angle formed by the first air deflector and the indoor unit panel is set to be θ, and when the air conditioner is turned on, the first air deflector is first opened to a default angle, and is set to be θ m The user can set different refrigeration modes (namely, change the air guide angle of the first air guide plate) through the remote control equipment, and the embodiment uses the default position (theta m ) Stop-motion position 1 (θ) 1 ) Stop-motion position 2 (theta) 2 ) And stop-motion position 3 (θ) 3 ) These four angles are exemplified, and θ is set 3 ＞θ 2 ＞θ m ＞θ 1 The method comprises the steps of carrying out a first treatment on the surface of the According to the condensation experimental phenomenon, the smaller the air guiding angle of the first air guiding plate is, the easier the condensation is, the faster the current ambient humidity of the indoor unit rises, so the corresponding preset time is required to be relatively shorter so as to trigger the second air guiding plate to open to the condensation preventing angle relatively earlier, based on the preset time, four preset times corresponding to the four angles can be set, namely: t (T) 1 Corresponding to theta 1 ，T m Corresponding to theta m ，T 2 Corresponding to theta 2 ，θ 3 Corresponding T 3 And T is 3 ＞T 2 ＞T m ＞T 1 。
Thus, in step S104, it is determined whether the current running time reaches the corresponding preset time, that is: judging whether the running 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 the air guiding angle theta of the first air deflector 1 Whether the next running time reaches the preset time T 1 . Meanwhile, whether the current environmental humidity of the indoor unit reaches a first preset humidity value is matched and judged, 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 deflector is inversely related to the air guiding angle of the first air deflector, and the anti-condensation angle of the second air deflector is an included angle between the anti-condensation state and the closed state of the second air deflector.
In the present embodimentThe anti-condensation angle of the second air deflector is determined according to the air guiding angle of the first air deflector, and taking the above set four air guiding angles of the first air deflector as an example, the second air deflector can set four anti-condensation angles corresponding to the four angles, namely: phi 1 Corresponding to theta 1 ，Φ m Corresponding to theta m 、Φ 2 Corresponding to theta 2 ，Φ 3 Corresponding T 3 Also according to the condensation experimental phenomenon that the smaller the air guide angle of the first air guide plate is, the easier the condensation is, the phi can be obtained 3 ＞Φ 2 ＞Φ m ＞Φ 1 . It can be appreciated that: when the first air deflector is at the air guiding angle theta 1 The running time reaches the preset time T 1 When the current environmental humidity of the indoor unit does not reach the first preset humidity value, the second air deflector can be controlled to be opened to the condensation preventing angle phi 1 。
It should be noted that, the wind guiding angle of the first wind guiding plate and the anti-condensation angle of the second wind guiding plate are not limited to the above 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, acquiring current running time;
s202, judging whether the current running time reaches the corresponding preset time, if not, entering a step S203, and if so, returning to the step S104 to further judge whether the current environment 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 is changed, 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; and determining a smaller wind guiding angle therein;
s205, taking the preset time corresponding to the smaller air guide angle as the corresponding preset time for newly judging the current running time according to the preset corresponding relation.
In the operation process of the indoor unit, the corresponding preset time is confirmed in real time according to the current air guide angle of the first air guide plate, and because different refrigeration modes can be adjusted by a user in the operation process of the indoor unit, the air guide angle of the first air guide plate can be changed, and the corresponding preset time needs to be correspondingly adjusted.
In a specific scenario, taking the above-set four wind guiding angles of the first wind guiding plate as an example, for example: when the air guide angle of the first air guide plate is theta m And at the air-guiding angle theta m The current running time does not reach the preset time T m When the first air deflector is judged to be at the air guiding angle theta m Changing to the air guiding angle theta 1 At this time, the air guide angle θ needs to be compared m And air guiding angle theta 1 The size of (2) can be known as θ m ＞θ 1 Therefore, a smaller air guiding angle θ is required 1 Corresponding preset time T 1 And the corresponding preset time of the current running time is used as a new judgment. Furthermore, for example, the first air deflector is positioned at an air guiding angle θ m Changing to the air guiding angle theta 2 It can be seen that θ 2 ＞θ m At this time, the smaller air guiding angle theta m Corresponding preset time T m Still the corresponding preset time for judging the current running time.
