The air supply control method of the air conditioner can comprise a rapid heat exchange stage, a comfortable air supply stage and an intelligent energy-saving stage which are sequentially switched.
Specifically, in the rapid heat exchange stage: the fan of the air conditioner is in a high-speed mode, and the first air deflector 40, the second air deflector 42, the third air deflector 44 and the fourth air deflector 46 all continuously swing.
In the comfortable air supply stage: the fan of the air conditioner is in a medium speed mode, and the first air deflector 40, the second air deflector 42, the third air deflector 44 and the fourth air deflector 46 all continuously swing.
In the intelligent energy-saving stage: the fan of the air conditioner is in a low-speed mode; when the air conditioner is in a cooling mode, the first air deflector 40 and the second air deflector 42 are controlled to close the downward opening of the air outlet 16, and the third air deflector 44 and the fourth air deflector 46 continuously swing; when the air conditioner is in a heating mode, the first air deflector 40 and the second air deflector 42 are controlled to continuously swing, and the third air deflector 44 and the fourth air deflector 46 close the forward opening of the air outlet 16.
In some embodiments, the blower of the air conditioner may be a crossflow blower 20, and the crossflow blower 20 may be pre-configured with at least three modes, i.e., a high speed mode, a medium speed mode, and a low speed mode.

The quick heat exchange stage can basically meet the temperature requirement of a user, so that the comfortable air supply stage is a transition stage, and the main adjustment target is to slowly approach the target temperature on the basis of the current indoor temperature to realize comfortable air supply.
In this stage, the fan of the air conditioner is switched to the medium speed mode to reduce the wind speed and the flow rate of the heat exchange airflow, and the first air deflector 40, the second air deflector 42, the third air deflector 44 and the fourth air deflector 46 continue to continuously swing back and forth according to the pace of the rapid heat exchange stage, so that comfortable air supply is realized. In addition, in this stage, the contribution of the air disturbed by the four air deflectors to the heat exchange is increased.
The requirement of the user on the temperature can be completely met in the comfortable air supply stage, namely the indoor temperature can completely reach the target temperature set by the user. The main regulation target in the energy-conserving stage of wisdom is to maintain indoor temperature to compromise the experience sense of user in cooling mode or heating mode.
Because the first air deflector 40 and the second air deflector 42 are used for opening and closing the downward opening of the air outlet 16, and the third air deflector 44 and the fourth air deflector 46 are used for opening and closing the forward opening of the air outlet 16, in the intelligent energy-saving stage, the air conditioner is in the refrigeration mode, the first air deflector 40 and the second air deflector 42 are closed, and the refrigeration airflow is ensured not to be blown directly to the ground by only continuously swinging back and forth by the third air deflector 44 and the fourth air deflector 46 to guide the airflow forwards, so that the effect of preventing a user from being blown directly is achieved. Similarly, in the intelligent energy-saving stage, when the air conditioner is in the heating mode, the third air deflector 44 and the fourth air deflector 46 are closed, and only the first air deflector 40 and the second air deflector 42 are used for continuously swinging back and forth to conduct downward flow guiding, so that the heating air flow can be guaranteed to be directly blown to the ground, and the user experience is improved.
In addition, in the energy-conserving stage of wisdom, no matter be under refrigeration mode and the mode of heating, two aviation baffles in four aviation baffles are closed, only utilize two remaining aviation baffles to carry out the water conservancy diversion, also 16 parts of air outlet are sheltered from, can reach the throttle purpose simultaneously like this, reduce the air-out pressure of heat transfer air current, improve the velocity of flow increase of heat transfer air current, make heat transfer air current softer, the air-out distance is farther, it is higher with indoor air heat exchange efficiency, further improve user experience and feel.
Therefore, in the air supply control method of the embodiment, in the rapid heat exchange stage and the comfortable air supply stage, the four air deflectors continuously swing back and forth, the maximum air output is ensured, the indoor temperature approaches to the target temperature set by a user as soon as possible, air disturbance between adjacent regions and between diagonal regions can be enhanced, the distribution of a heat exchange airflow field is more uniform, and the heat exchange efficiency with indoor air is higher. At the energy-conserving stage of wisdom, the air conditioner is in under the refrigeration mode, only utilize third aviation baffle 44 and fourth aviation baffle 46 to continue continuous reciprocating swing, play the effect that prevents the direct-blow user, the air conditioner is in under the mode of heating, only utilize first aviation baffle 40 and second aviation baffle 42 to continue continuous reciprocating swing, carry out the water conservancy diversion downwards, can guarantee like this that the air that heats directly blows to ground, and the heat transfer air current is softer, the air-out distance is farther, and is higher with indoor air heat exchange efficiency, further improve user experience and feel.
Referring to fig. 8 and 9, fig. 8 is a state diagram of the indoor unit 1 in a rapid heat exchange stage or a comfort air supply stage according to an embodiment of the present invention, and fig. 9 is another state diagram of the indoor unit 1 in a rapid heat exchange stage or a comfort air supply stage according to an embodiment of the present invention.
Further, in any stage of the rapid heat exchange stage and the comfortable air supply stage, the swing pitches of the first air deflector 40 and the fourth air deflector 46 are kept consistent, and the swing pitches of the second air deflector 42 and the third air deflector 44 are kept consistent. By paced, it is understood that: the first air guiding plate 40 and the fourth air guiding plate 46 are opened and closed simultaneously, and the second air guiding plate 42 and the third air guiding plate 44 are opened and closed simultaneously. Therefore, synchronous air outlet in a cross region can be realized, the heat exchange air flow with forward air outlet and downward air outlet is ensured, the air outlet at the first side and the air outlet at the second side are ensured, the heat exchange air flow is prevented from being intensively blown forward or downward, and the condition that an indoor temperature field is uneven is avoided.
Further, in any stage of the rapid heat exchange stage and the comfortable air supply stage, when the first air deflector 40 and the fourth air deflector 46 are fully closed, the second air deflector 42 and the third air deflector 44 are fully opened, and when the first air deflector 40 and the fourth air deflector 46 are fully opened, the second air deflector 42 and the third air deflector 44 are fully closed.
For example, when the first air guiding plate 40 is fully opened, the second air guiding plate 42 is fully closed, that is, the second air guiding plate 42 swings from closed to open in the process of opening the first air guiding plate 40 from open to closed, so that the downward openings of the air outlets 16 controlled by the first air guiding plate 40 and the second air guiding plate 42 are always opened to a certain degree, and the non-uniform transverse heat exchange air flow is avoided.
In some embodiments, the swing frequency of each air deflector in the rapid heat exchange stage is higher than the swing frequency of each air deflector in the comfortable air supply stage. In the comfortable air supply stage, the requirement of the user on the temperature can be basically met, the temperature is slowly approached to the target temperature, and the comfortable air supply is realized, so that the swing frequency of each air deflector can be properly reduced in the comfortable air supply stage, and the power consumption is saved.
In some embodiments, the first switching condition from the fast heat-transfer phase to the comfort blowing phase is: the operation time of the rapid heat exchange stage reaches a first preset time; and/or the temperature difference between the indoor temperature and the target temperature set by the user is not greater than the preset temperature difference.
The two conditions may be applied simultaneously or alternatively. When simultaneously applied, the first switching condition is satisfied as long as any one of the two conditions is triggered.
In some specific embodiments, the first predetermined time is set to any value between 3min and 6min, for example, 3min, 4.5min, 6min, and the like. For example, when the time for entering the rapid heat exchange stage reaches 5min, the rapid heat exchange stage is switched to the comfortable air supply stage.
In some specific embodiments, the preset temperature threshold is set to any value between 1 ℃ and 3 ℃, for example, 1 ℃, 2 ℃,3 ℃, etc. For example, the target temperature set by the user in the cooling mode is 26 ℃, the preset temperature threshold is 2 ℃, and when the indoor temperature reaches 28 ℃, the rapid heat exchange stage is switched to the comfortable air supply stage. For another example, the target temperature of the heating mode set by the user is 23 ℃, the preset temperature threshold is 3 ℃, and when the indoor temperature reaches 20 ℃, the rapid heat exchange stage is switched to the comfortable air supply stage.
In some embodiments, the second switching condition from the comfortable blowing stage to the intelligent energy saving stage is: the operation time of the comfortable air supply stage reaches a second preset time.
In some specific embodiments, the second preset time period is set to any value between 5min and 15 min. For example, 5min, 10min, 15min, etc.
In some embodiments, when the air conditioner is in the heating mode, the electric heating device 90 of the air conditioner is turned on during the rapid heat exchange phase, and the electric heating device 90 of the air conditioner is turned off during the comfort blowing phase. The electric heating device 90 may be a PTC semiconductor heating ceramic, which can assist in heating the heat exchange air flow after being energized, so as to complete the rapid heat exchange stage as soon as possible in the rapid heat exchange stage in the heating mode.
