With reference to FIG. 1 , an embodiment of the present disclosure provides a method for controlling the air output from an outdoor unit of an air conditioner. An air outlet grille with swingable blades is provided at the air outlet of the outdoor unit of the air conditioner, and the method includes:

S20, controlling the swing blade to perform the actions of keeping the horizontal and tilting respectively, and each action is kept for a preset time period, so that the air outlet grille respectively performs horizontal air supply and inclined air supply;

S30. After each action is maintained for a preset period of time, obtain the ambient temperature corresponding to each action;

S40. Control the swing blade to perform an action corresponding to the minimum value in the obtained ambient temperature, so that the air outlet grille sends air according to the action state of the swing blade.

Embodiments of the present disclosure may provide a solution for controlling the air output from an outdoor unit of an air conditioner. Specifically, by obtaining the ambient temperature of the swing blade on the air outlet grille at a specific position, the swing blade can be controlled to swing to a direction that is more in line with the natural wind, so that the heat dissipated by the outdoor unit of the air conditioner can be sent to a farther position. Improve the cooling effect of the outdoor unit of the air conditioner.

In the embodiment of the present disclosure, when the outdoor unit of the air conditioner is supplying air, the swing blades of the outdoor unit of the air conditioner are controlled to perform the actions of maintaining the level and tilting, respectively, each action is maintained for a preset time, and the ambient temperature is obtained corresponding to each action, so that the The swing blade performs the action corresponding to the minimum value of the ambient temperature, so that the swing blade can be turned over to the direction where the ambient temperature is lower, so that the air outlet direction of the outdoor unit of the air conditioner conforms to the direction of the natural wind, so as to disperse the outdoor unit of the air conditioner. The heat generated is sent to a farther location, improving the heat dissipation effect of the outdoor unit of the air conditioner.

When the air outlet direction of the outdoor unit of the air conditioner matches the natural wind direction, driven by the natural wind direction, the airflow sent by the outdoor unit of the air conditioner can flow to a farther position; when the outlet direction of the outdoor unit of the air conditioner does not match the natural wind direction, the The wind direction will produce a certain resistance to the air flow sent by the outdoor unit of the air conditioner, reducing the flow distance of the air flow.

Keeping the swing blade horizontal means that the blade surface of the swing blade is in a horizontal state; The swing blade is turned over and inclined, for example, the swing blade is turned up or down to present a state of upward or downward inclination relative to the horizontal plane, or the swing blade is turned to the left or right to present a relatively vertical plane (perpendicular to where the air outlet is located). plane and horizontal plane) tilted to the left or right.

When the swing blade is kept horizontal, the air flow flows in the horizontal direction after passing through the air outlet; when the swing blade is kept inclined, the air flow is deflected after passing through the air outlet. A biased flow can be either an upward flow or a downward flow.

As an example, by arranging a transmission mechanism connected with the rotating shaft of the pendulum blade, and a drive mechanism connected with the transmission mechanism, the overturning of the pendulum blade is realized. The driving mechanism can be a motor, and the motor drives the transmission mechanism to move, and the transmission mechanism drives the rotating shaft to rotate, thereby realizing the overturning of the swing blade. The specific structure of the transmission mechanism and the driving mechanism, as well as the connection mode with the swing blade, can be realized by using the existing technology.

The ambient temperature refers to the temperature of the area near the outdoor unit of the air conditioner. As shown in FIG. 2 , the outdoor unit of the air conditioner is installed in the outdoor environment. When the air conditioner system performs cooling, the outdoor unit of the air conditioner can dissipate heat through the condenser provided inside to cool the refrigerant. Optionally, the ambient temperature can be detected by arranging a temperature sensor on the outdoor unit of the air conditioner.

The swing blade maintains a preset time in each action of maintaining the level and tilting, so that the ambient temperature will change differently. By obtaining the ambient temperature under the corresponding action, you can know the air outlet direction of the outdoor unit of the air conditioner and the natural environment. Is the wind direction more consistent? If the air outlet direction of the outdoor unit of the air conditioner is more consistent with the natural wind direction, the air outlet air flow of the outdoor unit of the air conditioner can carry the heat to a farther place, and the obtained ambient temperature is lower; If the wind direction is not consistent, the distance carried by the air outlet of the outdoor unit of the air conditioner to carry heat is relatively small compared to the case of the same wind direction, and the obtained ambient temperature is also higher than the case of the same wind direction.

As an example, the preset time period may be timed by setting a timer circuit in the outdoor unit of the air conditioner.

As an example, the preset duration is 2min. When the swing blade is kept horizontal or tilted for 2 minutes, the ambient temperature can reach a relatively stable state, which is convenient to obtain a relatively accurate ambient temperature.

As an example, by setting the controller to control the swing blade to perform the actions of maintaining the level and turning the tilt respectively.

As an example, the controller can also control the swing blade to perform an action corresponding to the minimum value in the obtained ambient temperature, so that the air outlet grille sends air according to the action state of the swing blade.

As an example, controlling the swing blade to perform the action corresponding to the minimum value in the obtained ambient temperature includes:

Compare the magnitude of the obtained ambient temperature and determine the minimum value;

Get the swing action corresponding to the minimum value.

The embodiment of the present disclosure finds the action state of the swing blade that can minimize the ambient temperature by comparing the ambient temperature of the swing blade in different operation states, so that the air outlet direction of the outdoor unit of the air conditioner can conform to the natural wind direction, thereby fully dissipating heat.

In some embodiments, the act of flipping the tilt includes flipping up and flipping down. When the natural wind direction hits the outdoor unit of the air conditioner and the nearby area, it is easy to generate upward or downward flow. The embodiment of the present disclosure can make the air outlet direction of the outdoor unit of the air conditioner easier and natural by controlling the swinging blade to be turned upward or downward. The wind is close.

If the natural wind direction near the outdoor unit of the air conditioner is mainly upward blowing, after the swing blade is turned upward, the ambient temperature is lower than that after the downward turning; if the natural wind direction near the outdoor unit of the air conditioner is mainly downward blowing, Then, after the swing leaf is turned downward, the ambient temperature is lower than that of the upward turning.

In some embodiments, flipping up is flipping up a first angle relative to a horizontal position, and flipping down is flipping down a first angle relative to a horizontal position. By setting the first angle in the embodiment of the present disclosure, the upward and downward turning amplitudes of the swing blade can be controlled more accurately.

As an example, the first angle is 45°. 45° is an angle between the horizontal and vertical, and turning the swing blade at the first angle can increase the probability of being more in line with the natural wind direction.

In some embodiments, controlling the swing leaf to perform the actions of maintaining the level and turning the tilt respectively, and each action is kept for a preset duration, including: controlling the swing leaf to perform the actions of keeping the level, turning up and turning downward in sequence, and each action is remain for the preset duration.

In this way, a relatively stable ambient temperature of the swing blade under each action can be obtained, which is convenient for subsequent comparison of the ambient temperature, and can provide a more accurate judgment for controlling the swing blade to perform the best action.

As an example, the preset duration of each action of the swing leaf is equal. For example, keep the horizontal state for 2 minutes, then flip up for 2 minutes, and finally flip down for 2 minutes.

As an example, it is also possible to control the swing blade to perform the actions of keeping horizontal, turning downward and turning upward in sequence, and each action is kept for a preset duration. The technical effect of the present application can also be achieved by changing the order of flipping up and flipping down.

In some embodiments, after each action is maintained for a preset period of time, acquiring the ambient temperature corresponding to each action includes: acquiring the first ambient temperature after the swing blade is kept horizontally for a preset period of time; After the time period is set, the second ambient temperature is acquired; after the swing blade is turned downward for a preset period of time, the third ambient temperature is acquired. Through the embodiments of the present disclosure, it is possible to obtain the corresponding ambient temperature under different action states of the swing blade.

As an example, the method for controlling the air output from the outdoor unit of the air conditioner includes:

After the outdoor unit of the air conditioner is turned on, the wind direction of the swing blade is horizontal for 2 minutes, and the ambient temperature sensor records the temperature T0;

The swing leaf is turned over, and the wind is blown upward at 45° for 2 minutes, and the temperature T1 is recorded;

The swing leaf is turned over again, and the wind blows out in the downward direction of 45° for 2 minutes, and the temperature T2 is recorded;

Compare the sizes of T0, T1, and T2, select the action state of the swing blade corresponding to the minimum value, and control the swing blade to discharge air in this direction.

In this way, the ambient temperature corresponding to each action maintained for a preset period of time can be obtained more accurately, and the swing blade can be made to discharge air according to the action state corresponding to the minimum ambient temperature.

With reference to Fig. 2, in some embodiments, after controlling the swing blade to perform the action corresponding to the minimum value in the obtained ambient temperature, the method further includes:

S50, obtaining the current ambient temperature after a predetermined period of time;

S60, controlling the swing leaf to perform the actions of flipping up and flipping down in turn based on the current action, and each action maintains a set duration;

S70, respectively obtaining the fourth and fifth ambient temperatures corresponding to each action after the set duration;

S80: Control the swing blade to perform an action corresponding to the minimum value among the current ambient temperature and the fourth and fifth ambient temperatures, so that the air outlet grille supplies air according to the action state of the swing blade.

Through the embodiment of the present disclosure, the action state of the swing blade can be further adjusted, so that the action state of the swing blade is more in line with the natural wind direction. Specifically, after the swing blade performs the action corresponding to the minimum value in the obtained ambient temperature, the current ambient temperature is obtained first, and then the swing blade is controlled to continue to adjust based on the current action, for example, the upward turning and downward turning are performed in turn. After each action is maintained for a set period of time, the fourth and fifth ambient temperatures are obtained, and the three ambient temperatures are compared again to obtain a better action state of the swinging blade. In this way, the action state of the swing blade can be more in line with the natural wind direction, which is beneficial to improve the heat dissipation effect of the outdoor unit of the air conditioner.

In some embodiments, controlling the swing leaf to perform the actions of turning up and turning downward in sequence based on the current action, includes: controlling the swing leaf to turn upward by a second angle relative to the current action and turn downward by a second angle relative to the current action in sequence , the second angle is smaller than the first angle.

The embodiment of the present disclosure controls the current movement of the swing blade as a reference, continues to perform flip adjustment, and in turn flips up a second angle relative to the current action and flips a second angle downward relative to the current action, so that the swing amplitude of the swing blade can be more accurately controlled , so that the air outlet direction of the outdoor unit of the air conditioner is more in line with the natural wind direction. Making the second angle smaller than the first angle can, on the one hand, prevent the swinging blade from turning back to the position before the last adjustment, which would cause the adjustment to fail. It is easy to obtain a more accurate swing blade position by fine-tuning the second angle smaller than the first angle.

As an example, the first angle is 45° and the second angle is 15°. In this way, after the position of the swing blade is roughly adjusted at 45°, the position of the swing blade can be finely adjusted at an angle of 15°, so as to achieve accurate adjustment of the position of the swing blade.
