All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
The embodiment provides a wind guiding blade control method, which can be applied to a controller of an air conditioner, and is shown in a flow chart of the wind guiding blade control method shown in fig. 1, and the method mainly comprises the following steps of S102 to S104:
step S102: and acquiring the current running mode and the wind guide blade angle of the air conditioner.
The operation modes comprise a heating mode and a refrigerating mode; the air conditioner may be a ceiling-mounted air conditioner as shown in fig. 2, and as shown in fig. 2, the air conditioner includes an indoor unit 21 and an outdoor unit 22, the indoor unit 21 and the outdoor unit 22 are connected by a refrigerant pipe 23 to form a refrigerant circuit, the indoor unit 21 includes a box-shaped main body 24, a square air inlet 25 and 4 air outlets 26a to 26d, the air outlets 26a to 26d are respectively provided with air guide blades 2a to 2d for adjusting the air outlet direction, and the air outlets 26a to 26d have the same shape and are in a slender rectangular shape.
The wind guide blades at the air outlets of the air conditioner are randomly divided into two groups of wind guide blades, for example, two wind guide blades at adjacent or opposite positions can be divided into one group, so that the angular speeds of the two groups of wind guide blades are the same or different, and the phenomenon that the indoor environment temperature distribution is uneven due to the fact that cold wind or hot wind blown out by the air conditioner faces one direction is avoided. In one embodiment, to further enhance the comfort of the indoor environment, the wind guiding blades in the opposite positions may be divided into a set of wind guiding blades, such as a first set of wind guiding blades may include wind guiding blades 2a and 2c, and a second set of wind guiding blades may include wind guiding blades 2b and 2d.
Step S104: the angular speed of the air guide blades is controlled based on the operation mode and the angle of the air guide blades, so that the air outlet of the air conditioner in the first direction is larger than the air outlet in the second direction in the heating mode, and the air outlet in the first direction is smaller than the air outlet in the second direction in the cooling mode.
When the operation mode is a heating mode, the angular velocities of the first group of wind guide blades and the second group of wind guide blades are in opposite phases, and when the operation mode is a cooling mode, the angular velocities of the first group of wind guide blades and the second group of wind guide blades are in the same phase.
The wind guiding blades at each air outlet of the air conditioner are respectively driven by motors connected with corresponding shafts so as to realize angle adjustment of the wind guiding blades, the motors can be stepping motors, the motors are driven by power supply currents output by corresponding driving devices, the controller of the air conditioner drives the motors by sending rotation instruction pulse signals to the driving devices corresponding to the wind guiding blades, so that the wind guiding blades rotate, meanwhile, the controller also sends rotation direction signals to the driving devices so as to control the rotation directions of the wind guiding blades, the wind guiding blade angles can be counted and identified by the controller to the rotation instruction pulse signals output by the driving devices, and the rotation instruction pulse signal frequency, namely the angular speed, is controlled according to the angles so as to realize the control of the angular speed of the wind guiding blades.
According to the characteristic that hot air easily floats upwards and cold air easily sinks, when the wind guiding blade angle is close to the direction towards the ground in the heating mode, the angular velocity of the wind guiding blade is controlled to be smaller, and the wind guiding blade angle is controlled to be larger when the wind guiding blade angle is close to the direction towards the indoor top, so that the air outlet quantity of the air conditioner in the ground direction is larger, as much hot air as possible is blown to the ground direction, and the hot air is prevented from floating upwards at the indoor upper part. In the refrigerating mode, when the angle of the air guide blade is closer to the direction towards the indoor top, the angular speed of the air guide blade is controlled to be smaller, and when the angle of the air guide blade is closer to the direction towards the ground, the angular speed of the air guide blade is controlled to be larger, so that as much cold air as possible is blown to the indoor upper area, and the cold air is prevented from sinking at the indoor bottom.
In one embodiment, the air conditioner is a ceiling type air conditioner, the rotation angle of the air guide blade ranges from 0 to 90 degrees, when the angle of the air guide blade is 0 degrees, the air outlet direction of the air conditioner is a first direction which is vertically directed to the ground, and when the angle of the air guide blade is 90 degrees, the air outlet direction of the air conditioner is a second direction which is perpendicular to the first direction.
Referring to the schematic view of the air-guiding blade angles of the air conditioner shown in fig. 3, the rotation angle ranges of the air-guiding blades 2 a-2 d are all 0-90 degrees, when the air-guiding blade angle θ is closer to 0 degrees, the air-outlet direction of the air conditioner is closer to the first direction y vertically pointing to the ground, and when the air-guiding blade angle θ is closer to 90 degrees, the air-outlet direction of the air conditioner is closer to the second direction x parallel to the ceiling 31 and the ground, and the second direction x is perpendicular to the first direction y.
Because hot air is easy to rise to the indoor ceiling under the heating mode, through controlling the angular velocity of the wind guiding blades during heating, the angular velocity of the wind guiding blades of the first group and the angular velocity of the wind guiding blades of the second group are controlled to be opposite phases, the air outlet quantity in the first direction is larger than the air outlet quantity in the second direction, the air outlet direction of the air conditioner is closer to the ground, the air outlet quantity is more, most of air outlet in the heating scene is dispersed and sent to the lower indoor position, and the uniform distribution of indoor environment temperature is realized after the high-temperature air rises.
The cold air is easy to drop to the lower indoor position in the refrigeration mode, the angular speed of the air guide blades is controlled in the refrigeration mode, the angular speed of the first group of air guide blades and the angular speed of the second group of air guide blades are controlled to be in the same phase, the air outlet quantity in the first direction is smaller than the air outlet quantity in the second direction, the more the air outlet direction of the air conditioner is close to the air outlet quantity of the ceiling, most of the air outlet of the air conditioner in the refrigeration scene is distributed and sent to the higher indoor position, and the uniform distribution of the indoor environment temperature is realized after the low-temperature air is dropped.
According to the air guide blade control method, the angular speeds of the air guide blades are adjusted according to the operation mode of the air conditioner and the angle of the air guide blades, so that the control of the air supply quantity in different directions under the refrigerating mode and the heating mode is realized, the non-uniform indoor environment temperature is avoided, the angular speeds of the first group of air guide blades and the second group of air guide blades are opposite in phase to each other under the heating mode, the angular speeds of the first group of air guide blades and the second group of air guide blades are the same in phase to each other under the refrigerating mode, the indoor wide area air supply can be realized only by adjusting the angular speeds of the air guide blades, the air conditioner can effectively reach the area where a user is located, and the comfort of the air conditioner is improved.
The conventional angular velocity control method of the wind guiding blade is as shown in fig. 4a, and the wind guiding blade is controlled to swing up and down according to a certain angular velocity, and stays for a certain time at an upper limit position or a lower limit position. Referring to the indoor air flow simulation schematic diagram in the conventional wind guiding blade angular velocity control mode shown in fig. 4b and the indoor temperature distribution simulation schematic diagram in the conventional wind guiding blade angular velocity control mode shown in fig. 4c, fig. 4b shows an indoor section view from the air outlet to the wall on the other side, the upper side of fig. 4b is the ground, the lower side of the ceiling is the ground, the upper left end is the air outlet of the air conditioner, the symbol in the drawing shows the position reached by the air flow blown out by the air outlet of the air conditioner at regular intervals, and fig. 4c is the simulation calculation result of the temperature distribution simulation in the same area as fig. 4 b.
In order to make the indoor temperature distribution as uniform as possible, the present embodiment provides two embodiments for controlling the angular velocity of the wind guiding blades based on the operation mode and the wind guiding blade angle, and may be specifically implemented with reference to the following first embodiment and the second embodiment:

in this embodiment, the angular velocity of the air guide vane is controlled in stages so that the air conditioner supplies air downward Fang Duo during heating and supplies air upward during cooling, and the method can be specifically executed with reference to the following steps (1) to (2):
step (1): the plurality of operating phases are divided based on the rotation angle range of the wind guiding blades.
The number of the operation stages is more than or equal to 2, and the rotation angle range of the wind guide blade is divided into a plurality of stages on average so as to adjust the angular speed of the wind guide blade in each operation stage. For example, when the rotation angle range of the wind guiding blade is 0 to 90 degrees, it may be divided into two operation stages of 0 to 45 degrees and 45 to 90 degrees; it can be divided into three operation stages of 0-30 degrees, 30-60 degrees and 60-90 degrees, or six operation stages of 0-15 degrees, 15-30 degrees, 30-45 degrees, 45-60 degrees, 60-75 degrees and 75-90 degrees.
Step (2): and controlling the wind guide blade to run at different angular speeds in each running stage based on the running mode and the wind guide blade angle.
When the operation mode is a heating mode, the angular speed of the wind guiding blade is positively correlated with the wind guiding blade angle, and when the operation mode is a cooling mode, the angular speed of the wind guiding blade is negatively correlated with the wind guiding blade angle.
According to the air rising acceleration alpha= (g/T ') (T-T ') -kv, T is the air-conditioner air-out temperature, T ' is the ambient air temperature, g is gravity acceleration, k is resistance coefficient, v is air speed, and the inventor researches that the rising acceleration is generated when the air-conditioner air-out temperature is higher than the ambient temperature in heating operation; conversely, a descending acceleration is generated during refrigeration, so that high-temperature air outlet higher than ambient temperature during heating can ascend and move towards the ceiling plate; and low-temperature air outlet lower than ambient temperature can move downwards towards the ground during refrigeration. If the air guide blade rotates at a certain speed, indoor temperature distribution is uneven, and downward Fang Duo air supply is required during heating, and more air supply is required during cooling. If the existing angular speed control method of the wind guide blade is adopted, the wind guide blade stops at the upper limit and the lower limit, the problem of uneven indoor overall temperature can occur, and the temperature regulating effect is weakened from the air outlet in sequence.
According to the invention, the air guide blades are controlled to rotate at different angular speeds in different operation stages, and in a heating mode, the angular speed of the air guide blades is controlled to be increased along with the increase of the angle of the air guide blades when the air guide blades enter the next operation stage, so that the air outlet of the air conditioner towards the ground is larger than the air outlet towards the ceiling during heating operation. In the refrigeration mode, when the angle of the air guide blade is increased to enter the next operation stage, the angular speed of the air guide blade is controlled to be reduced, so that the air outlet of the air conditioner towards the ground is smaller than the air outlet towards the ceiling during refrigeration operation. By controlling the angular speed of the air guide blade in stages, the accurate control of the air output of different areas is realized, and the indoor temperature distribution can be more uniform.

The air guide blades are controlled to rotate at a smaller angular speed when the angle of the air guide blades is in a range of 45-90 degrees in a refrigerating mode, so that the air outlet time of the air conditioner to the upper indoor area is increased, the amount of cold air blown to the ceiling is increased, and the cold air is further reduced to realize uniform distribution of indoor temperature.

Embodiment two:
in this embodiment, the angular velocity of the wind guiding blade is continuously adjusted in real time according to the wind guiding blade angle, and the method may be specifically performed with reference to the following steps 1 to 2:
step 1: when the operation mode is a heating mode, the initial angle of the first group of air guide blades is set to be 0 degree, the initial angle of the second group of air guide blades is set to be 90 degrees, the angular speed of the first group of air guide blades and the angular speed of the second group of air guide blades are respectively controlled based on the angles of the first group of air guide blades, when the angle of the second group of air guide blades is 0 degree, the air outlet of the second group of air guide blades is controlled to be larger than the air outlet of the first group of air guide blades, and when the angle of the first group of air guide blades is 0 degree, the air outlet of the first group of air guide blades is controlled to be larger than the air outlet of the second group of air guide blades.
In the heating mode, the angular velocity is calculated as ω=ω m X (a+θ/90), ω is angular velocity, ω m For average angular velocity, a is a constant (such as may be 0.5) and θ is the air guide vane angle. The initial angles of the first group of wind guide blades and the second group of wind guide blades are set to be different by 90 degrees, so that the angles of the first group of wind guide blades and the second group of wind guide blades are opposite phases, the angular velocities of the first group of wind guide blades and the second group of wind guide blades are opposite phases, the corresponding angular velocities are calculated according to the current wind guide blade angles, the wind guide blades are controlled to rotate according to the calculated angular velocities, and meanwhile, the angles of the wind guide blades are increased by omega x t. Through adjusting the angular velocity of the wind guide blades in real time according to the angular velocity calculation formula under the heating mode, and setting the initial angles of the first group of wind guide blades and the second group of wind guide blades to be opposite phases, hot air blown to the ground under the heating state can be always more than hot air blown to the indoor upper part, the uniform temperature distribution under the heating state is realized, and the user experience is improved.
In a specific embodiment, when the average angular velocity is 60deg/s and a is 0.5, referring to the continuous control of the heating mode and the angle and angular velocity change condition diagram shown in fig. 7a, the initial angle of the first set of wind guiding blades is 0 degrees, the initial angle of the second set of wind guiding blades is 90 degrees, the angular velocities of the first set of wind guiding blades and the second set of wind guiding blades are opposite to each other, the 0 degree position is set to rotate to 90 degrees to be in the positive direction, and the angular velocity of the first set of wind guiding blades is gradually increased from 30deg/s to 90deg/s in the process of rotating from 0deg to 90 deg; in the process that the first group of wind guiding blades rotate from 90 degrees to 0 degrees, the angular speed of the second group of wind guiding blades gradually changes from-90 deg/s to-30 deg/s.
Because the angular speed control mode of the existing wind guide blades generally controls the wind guide blades to rotate at the same angle and angular speed under a heating mode, the air outlet is larger when the air outlet direction faces downwards to the ground, the air outlet is smaller when the air outlet direction faces upwards to the ceiling, the interrelation among the angles of the wind guide blades can influence the air quantity blown out by the air outlet, and the real uniform temperature distribution control cannot be effectively realized.
The angular velocity of the wind guide blade provided in this embodiment is in a proportional relationship with the wind guide blade angle, and the angular velocity is smaller when the wind guide blade angle is closer to 0 degrees, so as to increase the hot wind blown to the ground. The continuous angular velocity adjusting mode and the air output control mode can improve the temperature distribution during heating:
assuming that the air outlet area at the uppermost point of the air guide blades is Su (when the angle of the air guide blades is 90 degrees), the air outlet area at the lowermost point of the air guide blades is Sd (when the angle of the air guide blades is 0 degrees), the air outlet volume of the first group of air guide blades is F1, the air outlet volume of the second group of air guide blades is F2, and the total air outlet volume of the air conditioner is FA, in fig. 7a, the air outlet volume of each air guide blade group at the time t1 is proportional to the air outlet area, f1=fa×su/(su+sd), f2=fa×sd/(su+sd), and because the time Su > Sd at the time t1, the air outlet volume of the second group of air guide blades at the lowermost point of the air guide blades in the indoor ground direction can be increased, the air outlet volume in the indoor ground direction at the time t2 can be changed to the opposite values by increasing the air outlet volume at the lowermost point of the first group of the air guide blades at the time t 2. Namely, when the angle of the second group of wind guiding blades is 0 degree, the air outlet of the second group of wind guiding blades is controlled to be larger than the air outlet of the first group of wind guiding blades, and when the angle of the first group of wind guiding blades is 0 degree, the air outlet of the first group of wind guiding blades is controlled to be larger than the air outlet of the second group of wind guiding blades, so that the uniform temperature distribution during heating is realized.
In order to verify the effect of the continuous control manner of the air guide blade, in this embodiment, the indoor temperature distribution in the continuous adjustment manner of the air guide blade in the heating mode is simulated, for convenience of comparison, see the schematic diagram of the linear change of the air guide blade angle with respect to time and the change trend diagram of the angular velocity of the air guide blade at the corresponding time, as shown in fig. 8a, for the convenience of comparison, the indoor temperature distribution in the continuous adjustment manner of the angular velocity of the air guide blade in the heating mode is simulated and calculated by setting the air outlet temperature of the air conditioner to 50 degrees and the indoor environment temperature to 10 degrees, so as to obtain the indoor airflow distribution in the heating mode shown in fig. 8b and the indoor temperature distribution in the heating mode shown in fig. 8c, and as can be seen from fig. 8b and 8c, when the air guide blade angle changes linearly with respect to time, the indoor temperature distribution has the characteristic of collecting high-temperature air to the ceiling, and the comfort of users is reduced.
Let the air-conditioner air-out temperature be 50 degrees, the indoor environment temperature be 10 degrees, ω=ω m And x (0.5+θ/90), and performing simulation calculation on the indoor temperature distribution of the air guide blade in fig. 7a in the continuous control mode in the heating mode to obtain an indoor airflow distribution of the air guide blade in the continuous control mode in the heating mode shown in fig. 7b and an indoor temperature distribution of the air guide blade in the continuous control mode in the heating mode shown in fig. 7c, wherein the change condition of the angular velocity of the air guide blade is shown in fig. 7a, the smaller the angular velocity of the air guide blade is, the larger the angular velocity of the air guide blade is, the air flow blown out by the air outlet of the air conditioner can reach the corresponding position at regular intervals from fig. 7b, and compared with fig. 8c, the indoor temperature distribution of the angular velocity of the air guide blade in the continuous control mode provided by the embodiment is more uniform, and the comfort of a user is improved.
Step 2: when the operation mode is a heating mode, the initial angles of the first group of wind guide blades and the second group of wind guide blades are set to be the same angle, and the angular speed of the first group of wind guide blades and the angular speed of the second group of wind guide blades are respectively controlled based on the angles of the wind guide blades.
In the cooling mode, the angular velocity calculation is ω=ω m X (b- θ/90), b is a constant (such as may be 1.5). The initial angles of the first group of wind guide blades and the second group of wind guide blades are set to be the same, so that the angles of the first group of wind guide blades and the second group of wind guide blades are in the same phase. By adjusting the wind-guiding blade in real time according to the angular velocity calculation formula in the refrigeration modeAngular velocity to set the initial angle of first group wind guiding blade and second group wind guiding blade to the same phase place, can make the most cold wind of air conditioner blow to the ceiling direction, realized the temperature evenly distributed under the refrigeration state, promoted user experience.
In a specific embodiment, when the average angular velocity is 60deg/s and the value of a is 0.5, referring to the graph of the angles and the angular velocity change conditions of the air guiding blades under continuous control in the refrigeration mode as shown in fig. 9a, the initial angles of the first group of air guiding blades and the second group of air guiding blades are all 0 degrees, the angular velocities of the first group of air guiding blades and the second group of air guiding blades are in phase with each other, and the angular velocities of the first group of air guiding blades and the second group of air guiding blades gradually decrease from 90deg/s to 30deg/s in the process of rotating from 0 deg. to 90 deg..
The angular velocity of the wind guide blade is inversely proportional to the wind guide blade angle, and the angular velocity of the wind guide blade is smaller when the wind guide blade angle is closer to 90 degrees, so that the cold wind blowing to the ceiling direction is increased. The continuous adjustment of the angular velocity can improve the temperature distribution during refrigeration:
in fig. 7b, when the air output of each air guiding blade group is proportional to the air outlet area at time t3, f1=fa×su/(2×su), f2=fa×sd/(2×sd), and since Su > Sd, the air output of the lowermost air guiding blade and the uppermost air guiding blade becomes the same, and at the same time, the upper angular velocity becomes smaller, so that more air can be sent to the indoor upper side, and the air guiding device is suitable for a refrigeration scene, that is, the smaller the angular velocity is when the air guiding blade angle is closer to 90 degrees in the refrigeration mode, so that the air output of cold air in the indoor upper region can be increased.
In order to verify the effect of the continuous control manner of the air guide blade, in this embodiment, the indoor temperature distribution when the angular velocity of the air guide blade is continuously adjusted in the heating mode is simulated, for convenience of comparison, the air outlet temperature of the air conditioner is set to be 15 degrees, the indoor environment temperature is set to be 35 degrees, and the indoor air flow distribution in the cooling mode in the air guide blade angle and angular velocity control manner in fig. 8a is simulated and calculated to obtain the indoor air flow distribution in the cooling mode shown in fig. 8d and the indoor temperature distribution in the cooling mode shown in fig. 8e, and as can be seen from fig. 8d and 8e, when the air guide blade angle changes linearly with respect to time, the indoor temperature distribution has the characteristic that low-temperature air gathers below the air outlet, so that the comfort of a user is reduced.
Let the air-conditioner air-out temperature be 15 degrees, the indoor environment temperature be 35 degrees, ω=ω m And x (1.5-theta/90), and performing simulation calculation on the indoor temperature distribution of the angular velocity of the air guide blade in fig. 9a in the continuous control mode in the refrigeration mode to obtain an indoor airflow distribution of the angular velocity of the air guide blade in the continuous control mode shown in fig. 9b and an indoor temperature distribution of the angular velocity of the air guide blade in the continuous control mode shown in fig. 9c, wherein the angular velocity change condition of the air guide blade is that the smaller the larger the angle of the air guide blade is, the more the air guide blade is, the air flow blown out by the air conditioner air outlet reaches the corresponding position at intervals of a certain time can be seen in fig. 9b, and compared with fig. 8e, the indoor temperature distribution of the continuous control mode of the angular velocity of the air guide blade in the refrigeration mode provided by the embodiment is more uniform, and the comfort of a user is improved.
In one embodiment, the angular velocity of the wind guiding blade changes within ±50% of the average angular velocity, so as to improve the comfort of the air conditioner, and when the angular velocity of the wind guiding blade is controlled, the rate of change of the angular velocity of the wind guiding blade may be more than 20% and less than 50% (i.e. the difference between the angular velocities in the adjacent operation stages is 20% to 50% of the average angular velocity). The embodiment provides the situation that the ratio of the insufficient air flow area (i.e. the area with the indoor temperature above 30 degrees in the refrigeration mode) of the indoor air conditioner is changed by the air guide blade under different angular velocity change rates, referring to the graph of the ratio of the angular velocity change rate to the insufficient area in the refrigeration mode shown in fig. 10a, it can be seen from fig. 10a that the more the angular velocity change rate is greater, the more uniform the indoor temperature is, the more uniform the ratio of the insufficient air flow area of the air conditioner is when the angular velocity change rate is greater than 20%, the less the ratio of the insufficient air flow area of the air conditioner is, the more uniform the indoor temperature distribution is, the better the air conditioning refrigeration effect is, and the ratio of the insufficient air flow area of the air conditioner is basically saturated when the angular velocity change rate of the air guide blade is up to 50%, so that the indoor temperature distribution can be obviously more uniform when the angular velocity change rate of the air guide blade is greater than 20% and less than 50%, and the comfort of the air conditioner is improved.
In order to verify and compare the control effects of the above-mentioned angular velocity in the 2 operation stage, the 3 operation stage and the continuous control mode, the present embodiment provides a relationship diagram of the 2 operation stage control mode in fig. 5b, the 3 operation stage control mode in fig. 6b and the ratio of the insufficient area of the indoor air conditioner air flow in the continuous control mode in fig. 9a in the refrigeration mode, see the trend chart of the ratio change of the insufficient area in the different angular velocity control modes shown in fig. 10b, for obvious comparison, fig. 10b also shows the ratio of the insufficient area of the indoor air conditioner air flow corresponding to the angular velocity in the constant value control mode in fig. 8a, and the ratio of the insufficient area corresponding to the angular velocity in the constant value control mode is significantly higher than the ratio of the insufficient area in the continuous control mode, the 3 operation stage control mode and the 2 stage control mode in the application, so that the angular velocity 2 operation stage control mode, the 3 operation stage control mode and the continuous control mode in the application significantly improve the comfort of heating and refrigerating of the air conditioner.
According to the air guide blade control method provided by the embodiment, the angular speeds of the air guide blades are adjusted continuously or more than 2 stages, so that the air guide blades are changed according to the opposite phase during heating and the same phase during cooling, wide-area air supply in a room is realized only through the action of the air guide blades, meanwhile, uneven temperature distribution in the vertical direction of the space is reduced, and space comfort in the room is realized.
