The present invention is described in terms of particular embodiments, other advantages and benefits of the present invention will become apparent to those skilled in the art from the description herein, and it is understood that the described embodiments are intended to be illustrative of some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

The present embodiment provides a method for controlling a wind blade, which can be applied to a controller of an air conditioner, and referring to a flow chart of the wind blade control method shown in fig. 1, the method mainly includes the following steps S102 to S104:

step S102: and acquiring the current operation mode and the angle of the air guide blade of the air conditioner.

The operation modes comprise a heating mode and a cooling mode; the air conditioner may be a ceiling type 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 an air outlet direction, and the air outlets 26a to 26d have the same shape and are elongated and rectangular.

The air guide blades at the plurality of air outlets of the air conditioner are randomly divided into two groups of air guide blades, for example, two adjacent or opposite air guide blades can be divided into one group, so that the angular velocities of the two groups of air guide blades are the same or different, and the condition that the indoor environment temperature is unevenly distributed due to the fact that cold air or hot air blown out of the air conditioner faces one direction is avoided. In one embodiment, to further improve the comfort of the indoor environment, the air guiding blades in relative positions may be divided into a set of air guiding blades, such as a first set of air guiding blades may include air guiding blade 2a and air guiding blade 2c, and a second set of air guiding blades may include air guiding blade 2b and air guiding blade 2 d.

Step S104: and controlling the angular speed of the air guide blades based on the operation mode and the angle of the air guide blades so that the air output of the air conditioner to the first direction is greater than the air output of the air conditioner to the second direction in the heating mode, and the air output to the first direction is less than the air output of the air conditioner to the second direction in the cooling mode.

When the operation mode is a heating mode, the angular velocity of the first group of air guide blades and the angular velocity of the second group of air guide blades are opposite in phase, and when the operation mode is a cooling mode, the angular velocity of the first group of air guide blades and the angular velocity of the second group of air guide blades are the same in phase.

The air guide blades of each air outlet of the air conditioner are respectively driven by motors connected with corresponding shafts so as to realize angle adjustment of the air guide blades, the motors can be stepping motors, the motors are driven by power supply currents output by corresponding driving devices, a controller of the air conditioner drives the motors by sending rotation instruction pulse signals to the driving devices corresponding to the air guide blades so that the air guide blades rotate, meanwhile, the controller also sends rotation direction signals to the driving devices so as to control the rotation direction of the air guide blades, the angle of the air guide blades can be counted and identified by counting the rotation instruction pulse signals output to the driving devices by the controller, and the frequency, namely the angular speed, of the rotation instruction pulse signals is controlled according to the angle, so that the angular speed of the air guide blades is controlled.

According to the characteristic that hot air is easy to float up and cold air is easy to sink, in the heating mode, the angular speed of the air guide blade is controlled to be smaller when the angle of the air guide blade is closer to the direction towards the ground, and the angular speed of the air guide blade is controlled to be larger when the angle of the air guide blade is closer to the direction towards the indoor top, so that the air outlet amount of the air conditioner towards the ground direction is larger, hot air is blown to the ground direction as much as possible, and the hot air is prevented from floating up to the indoor upper part. In the cooling mode, the angular velocity of the air guide blade is controlled to be smaller when the angle of the air guide blade is closer to the direction towards the top of the room, and the angular velocity of the air guide blade is controlled to be larger when the angle of the air guide blade is closer to the direction towards the ground, so that cold air is blown to the upper area of the room as much as possible, and cold air is prevented from sinking to the bottom of the room.

In one embodiment, the air conditioner is a ceiling type air conditioner, the rotation angle range of the air guiding blade is 0 to 90 degrees, when the angle of the air guiding blade is 0 degrees, the air outlet direction of the air conditioner is a first direction perpendicular to the ground, and when the angle of the air guiding blade is 90 degrees, the air outlet direction of the air conditioner is a second direction perpendicular to the first direction.

Referring to the schematic angle diagram of the air guide blades of the air conditioner shown in fig. 3, the rotation angle ranges of the air guide blades 2a to 2d are all 0 to 90 degrees, when the angle θ of the air guide blade is closer to 0 degree, the air outlet direction of the air conditioner is closer to a first direction y which is vertically directed to the ground, and when the angle θ of the air guide blade is closer to 90 degrees, the air outlet direction of the air conditioner is closer to a second direction x which is parallel to the ceiling 31 and the ground, and the second direction x is perpendicular to the first direction y.

Because the hot air is easy to rise to the indoor ceiling in the heating 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 opposite in phase by controlling the angular speed of the air guide blades during heating, so that the air output in the first direction is greater than the air output in the second direction, the air output is more as the air outlet direction of the air conditioner is closer to the ground, most of the air outlet in the heating scene is dispersed and sent to the lower position indoors, and the uniform distribution of the indoor environment temperature is realized after the high-temperature air rises.

The cold air is easy to drop to the lower position in the room in the refrigeration mode, the angular speed of the air guide blades in the refrigeration mode is controlled, 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 air outlet quantity is more as the air outlet direction of the air conditioner is closer to the ceiling, most of the air outlet of the air conditioner in the refrigeration scene is dispersedly sent to the higher position in the room, and the uniform distribution of the indoor environment temperature is realized after the low-temperature air drops.

According to the control method of the air guide blades, the angular speed of the air guide blades is adjusted according to the operation mode of the air conditioner and the angle of the air guide blades, control over air supply quantities in different directions in the cooling mode and the heating mode is achieved, uneven indoor environment temperature is avoided, the angular speed of the first group of air guide blades and the angular speed of the second group of air guide blades are opposite in phase in the heating 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 same in phase in the cooling mode, indoor wide-area air supply can be achieved only by adjusting the angular speed of the air guide blades, air outlet of the air conditioner can effectively reach the area where a user is located, and comfort of the air conditioner is improved.

As shown in fig. 4a, a conventional method for controlling the angular velocity of a wind guide blade controls the wind guide blade to swing up and down at a certain angular velocity and to stay at an upper limit position or a lower limit position for a certain time. Referring to a schematic diagram of simulation of indoor airflow under the angular velocity control of the conventional air guide vane as shown in fig. 4b and a schematic diagram of simulation of indoor temperature distribution under the angular velocity control of the conventional air guide vane as shown in fig. 4c, where fig. 4b shows a cross-sectional view of an indoor from an air outlet to a wall on the other side, the upper side of fig. 4b is a ceiling, the lower side is a floor, and the upper left end is an air-conditioning outlet, and in the drawing, symbols indicate positions of air streams blown out from the air-conditioning outlet at regular intervals, and fig. 4c shows simulation calculation results of temperature distribution in the same area as fig. 4b, the inventors have found that, when the air guide vane is controlled by the angular velocity control of the conventional air guide vane during heating operation, the temperature of the air conditioner outlet is about 50 c, but the ambient temperature of the lower part of the indoor is low, the temperature distribution in the room is weakened from the air outlet in sequence, and the indoor temperature distribution is uneven, so that the comfort of a user is influenced.

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 air guide blade based on the operation mode and the air guide blade angle, and can be specifically executed with reference to the following first embodiment and second embodiment:

the first implementation mode comprises the following steps:

in this embodiment, the angular velocity of the air guide blade is controlled in stages so that the air conditioner blows more air downward during heating and more air upward during cooling, and the following steps (1) to (2) are specifically referred to:

step (1): a plurality of operation stages are divided based on the rotation angle range of the wind guide blade.

The number of the operation stages is more than or equal to 2, and the rotation angle range of the air guide blade is averagely divided into a plurality of stages so as to adjust the angular speed of the air guide blade in each operation stage. For example, when the rotation angle range of the air guide blade is 0-90 degrees, the air guide blade can be divided into two operation stages, namely a 0-45 degree stage and a 45-90 degree stage; the method can also be divided into three operation stages of 0-30 degrees, 30-60 degrees and 60-90 degrees, or divided into 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 air guide blades to operate at different angular speeds in each operation stage based on the operation mode and the air guide blade angle.

When the operation mode is a heating mode, the angular velocity of the air guide blade is in positive correlation with the angle of the air guide blade, and when the operation mode is a cooling mode, the angular velocity of the air guide blade is in negative correlation with the angle of the air guide blade.

According to the air rising acceleration alpha being (g/T ') (T-T ') -kv, T being the air conditioner outlet air temperature, T ' being the ambient air temperature, g being the gravity acceleration, k being the resistance coefficient, v being the air speed, the inventor finds that when the air conditioner outlet air temperature is higher than the ambient temperature during the heating operation, the rising acceleration is generated; on the contrary, the falling acceleration is generated during the cooling, so that the high-temperature outlet air with the temperature higher than the ambient temperature during the heating can move upwards towards the ceiling; and the low-temperature outlet air lower than the ambient temperature descends and moves towards the ground during refrigeration. If the air guide blade rotates at a constant speed, the indoor temperature distribution becomes uneven, and it is necessary to blow more air downward during heating and blow more air upward during cooling. If the existing angular speed control method of the air guide blade is adopted, the air guide blade stops at the upper limit and the lower limit, the problem of uneven indoor overall temperature can occur, and the temperature adjusting effect is weakened from the air outlet in sequence.

The invention controls the wind guide blades to rotate at different angular speeds in different operation stages, and under the heating mode, when the wind guide blades enter the next operation stage along with the increase of the angle, the angular speed of the wind guide blades is also controlled to increase, so that the air outlet amount of the air conditioner facing the ground is larger than the air outlet amount of the air conditioner facing the ceiling during the heating operation. In the refrigeration mode, when the air guide blade enters the next operation stage along with the increase of the angle of the air guide blade, the angular speed of the air guide blade is controlled to be reduced, so that the air outlet quantity of the air conditioner facing the ground is smaller than the air outlet quantity of the air conditioner facing the ceiling during the refrigeration operation. Through controlling the angular speed of the air guide blades in stages, the accurate control of the air output of different areas is realized, and the indoor temperature distribution is more uniform.

In an embodiment, when the number of the operation stages is equal to 2, the embodiment of controlling the wind guiding blade to operate at different angular velocities in each operation stage based on the operation mode and the wind guiding blade angle includes:

(1) when the operation mode is the heating mode, if the angle of the air guide blade is greater than or equal to 0 degrees and smaller than a first preset angle, the angular velocity of the air guide blade is controlled to be omega 1, and if the angle of the air guide blade is greater than or equal to the first preset angle and smaller than or equal to 90 degrees, the angular velocity of the air guide blade is controlled to be omega 2.

The second embodiment:

in this embodiment, the angular velocity of the air guide blade is continuously adjusted in real time according to the air guide blade angle, and specifically, the following steps 1 to 2 are referred to for execution:

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 velocity of the first group of air guide blades and the angular velocity of the second group of air guide blades are respectively controlled based on the angles of the groups of air guide blades, when the angle of the second group of air guide blades is 0 degree, the air output of the second group of air guide blades is controlled to be larger than the air output 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 output of the first group of air guide blades is controlled to be larger than the air output of the second group of air guide blades.

In the heating mode, the calculation formula of the angular velocity is ω ═ ω _m X (a + theta/90), omega is angular velocity, omega is _m For the average angular velocity, a is a constant (such as 0.5) and θ is the wind blade angle. The initial angle of the first group of air guide blades and the initial angle of the second group of air guide blades are set to have a phase difference of 90 degrees, so that the angles of the first group of air guide blades and the angles of the second group of air guide blades are opposite in phase, the angular velocity of the first group of air guide blades and the angular velocity of the second group of air guide blades are opposite in phase, the corresponding angular velocity is calculated according to the current angle of the air guide blades, the air guide blades are controlled to rotate according to the calculated angular velocity, and meanwhile, the angle of the air guide blades is increased by omega t. The angular speed of the air guide blades is adjusted in real time according to the angular speed calculation formula in the heating mode, and the initial angles of the first group of air guide blades and the second group of air guide blades are set to be opposite in phase, so that more hot air blown to the ground in the heating state is always blown to the upper part of the room, the uniform temperature distribution in 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 a variation diagram of the angle and the angular velocity of the air guiding blades under the continuous control of the heating mode as shown in fig. 7a, the initial angle of the first set of air guiding blades is 0 degree, the initial angle of the second set of air guiding blades is 90 degrees, the angular velocity of the first set of air guiding blades and the angular velocity of the second set of air guiding blades are in opposite phases, the 0 degree position is set to rotate to 90 degrees as the positive direction, and the angular velocity of the first set of air guiding blades is gradually increased from 30deg/s to 90deg/s in the process that the first set of air guiding blades rotates from 0 degree to 90 degrees; in the process that the first group of air guide blades rotate from 90 degrees to 0 degrees, the angular speed of the second group of air guide blades is gradually changed from-90 deg/s to-30 deg/s.

Because the angular velocity control mode of the existing air guide blades generally controls each air guide blade to rotate at the same angle and angular velocity in the heating mode, the air outlet is larger when the air outlet direction faces downwards to the ground, and the air outlet is smaller when the air outlet direction faces upwards to the ceiling, and the mutual relation among the angles of the air guide blades can influence the air outlet blowing quantity, so that the real temperature uniform distribution control cannot be effectively realized.

In the present embodiment, the angular velocity of the air guide blade is in direct proportion to the angle of the air guide blade, and the angular velocity is smaller as the angle of the air guide blade is closer to 0 degree, so as to increase the amount of hot air blown to the ground. The angular velocity continuous adjustment mode and the air outlet control mode can improve the temperature distribution during heating:

if the area of the air outlet at the uppermost point of the air guide blades is Su (when the angle of the air guide blades is 90 degrees), the area of the air outlet at the lowermost point is Sd (when the angle of the air guide blades is 0 degrees), the air output of the first group of air guide blades is F1, the air output of the second group of air guide blades is F2, and the total air output of the air conditioner is FA, and the air output of each air guide blade group at the time t1 in fig. 7a is proportional to the air outlet area, F1 (FA) Su/(Su + Sd), F2 (FA) Sd/(Su + Sd), since t1 is Su > Sd, the air output of the lowermost point of the second group of air guide blades at the time t1 can be increased, so that the air output toward the indoor ground direction at the time is increased, and F1 and F2 at the time t2 are opposite in value, and the air output of the lowermost point of the first group of air guide blades at the time t2 can be increased, so that the air output toward the indoor ground direction at the time of the air toward the air in heating is increased. When the angle of the second group of air guide vanes is 0 degree, the air outlet quantity of the second group of air guide vanes is controlled to be larger than that of the first group of air guide vanes, and when the angle of the first group of air guide vanes is 0 degree, the air outlet quantity of the first group of air guide vanes is controlled to be larger than that of the second group of air guide vanes, so that the uniform temperature distribution during heating is realized.

In order to verify the effect of the continuous control method of the air guide vane, the present embodiment performs analog simulation on the indoor temperature distribution when the angular velocity of the air guide vane is continuously adjusted in the heating mode, for comparison, see the angle and angular velocity variation trend chart of the air guide vane shown in fig. 8a, fig. 8a shows a schematic diagram of the linear variation of the angle of the air guide vane with respect to time and a variation trend chart of the angular velocity of the air guide vane at the corresponding time, assuming that the air conditioner outlet air temperature is 50 degrees and the indoor ambient temperature is 10 degrees, performs analog simulation calculation on the angle of the air guide vane in fig. 8a and the indoor temperature distribution in the angular velocity control method in the heating mode to obtain the indoor airflow distribution diagram in the heating mode shown in fig. 8b and the indoor temperature distribution diagram in the heating mode shown in fig. 8c, as can be seen from fig. 8b and 8c, when the angle of the air guide vane varies linearly with respect to time, the indoor temperature distribution has a characteristic that high-temperature air is concentrated toward the ceiling, reducing user comfort.

Let the air-conditioning air-out temperature be 50 deg.C, indoor environment temperature be 10 deg.C, omega ═ omega _m X (0.5+ θ/90), performing analog simulation calculation on the indoor temperature distribution of the angular velocity of the air guide vane in the continuous control mode in the heating mode in fig. 7a to obtain an indoor airflow distribution diagram of the angular velocity of the heating mode in the continuous control mode in fig. 7b and an indoor temperature distribution diagram of the angular velocity of the heating mode in the continuous control mode in fig. 7c, wherein when the angular velocity of the air guide vane changes, as shown in fig. 7a, the angular velocity is smaller when the angle of the air guide vane is smaller, and the angular velocity is larger when the angle of the air guide vane is larger, and it can be seen from fig. 7b that the airflow blown out from the air outlet of the air conditioner reaches the corresponding position at regular intervals, and compared with fig. 8c, fig. 7c provides more uniform indoor temperature distribution of the air guide vane in the continuous control mode, and improves user comfort.

Step 2: when the operation mode is a heating mode, setting the initial angle of the first group of air guide blades and the initial angle of the second group of air guide blades to be the same angle, and respectively controlling the angular speed of the first group of air guide blades and the angular speed of the second group of air guide blades based on the angle of each group of air guide blades.

In the cooling mode, the angular velocity calculation formula is ω ═ ω _m X (b-theta/90), b is a constant (such as may be 1.5). The initial angles of the first group of air guide blades and the second group of air guide blades are set to be the same, so that the angles of the first group of air guide blades and the angles of the second group of air guide blades are the same in phase. The angular velocity of the air guide blades is adjusted in real time according to the angular velocity calculation formula in the refrigeration mode, the initial angles of the first group of air guide blades and the second group of air guide blades are set to be the same phase, most cold air of the air conditioner can be blown to the ceiling direction, the temperature uniform distribution in the refrigeration state is achieved, 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 a variation diagram of the angles and angular velocities of the air guiding blades under the continuous control of the cooling mode as shown in fig. 9a, the initial angles of the first and second sets of air guiding blades are both 0 degrees, the angular velocities of the first set of air guiding blades and the second set of air guiding blades are in the same phase, and the angular velocities of the first and second sets of air guiding blades gradually decrease from 90deg/s to 30deg/s in the process of rotating from 0deg to 90 deg.

The angular velocity of the air guide blade is in inverse proportion to the angle of the air guide blade, and the angular velocity of the air guide blade is smaller when the angle of the air guide blade is closer to 90 degrees, so that cold wind blowing towards the ceiling is increased. The angular speed continuous adjustment mode can improve the temperature distribution during refrigeration:

in fig. 7b, when the air output of each air guide blade group is proportional to the outlet area at time t3, F1 ═ FA × Su/(2 × Su), and F2 ═ FA × Sd/(2 × Sd), and since Su > Sd, the air output of the lowermost air guide blade and the air output of the uppermost air guide blade are the same, and the upper angular velocity is decreased, more air can be sent to the indoor upper side, and the air guide blade is suitable for a refrigeration scenario, that is, the angular velocity is decreased as the air guide blade angle approaches 90 degrees in the refrigeration mode, and the air output of cool air in the indoor upper area can be increased.

In order to verify the effect of the continuous control method of the air guide vane, in this embodiment, analog simulation is performed on the indoor temperature distribution when the angular velocity of the air guide vane is continuously adjusted in the heating mode, for convenience of comparison, the air conditioner outlet air temperature is set to be 15 degrees, and the indoor ambient temperature is set to be 35 degrees, analog simulation calculation is performed on the air guide vane angle in fig. 8a and the indoor temperature distribution in the angular velocity control method in the cooling mode, so as to obtain the indoor airflow distribution diagram in the cooling mode shown in fig. 8d and the indoor temperature distribution diagram in the cooling mode shown in fig. 8e, and as can be seen from fig. 8d and 8e, when the air guide vane angle changes linearly with respect to time, the indoor temperature distribution has the characteristic that low-temperature air is gathered below the air outlet, and the comfort of a user is reduced.

Let the air-conditioning air-out temperature be 15 deg. C, indoor environment temperature be 35 deg. C, omega ═ omega _m X (1.5-theta/90), performing analog simulation calculation on the indoor temperature distribution of the angular velocity of the air guide vane in the continuous control mode in the cooling mode in fig. 9a to obtain an indoor airflow distribution diagram of the angular velocity of the cooling mode in the continuous control mode in fig. 9b and an indoor temperature distribution diagram of the angular velocity of the cooling mode in the continuous control mode in fig. 9c, wherein the angular velocity of the air guide vane changes as shown in fig. 9a, the angular velocity is smaller as the air guide vane angle is larger, the angular velocity is larger as the air guide vane angle is smaller, and the airflow blown out from the air outlet of the air conditioner reaches the corresponding position at regular intervals as shown in fig. 9b, fig. 9c is a view showing that, compared with fig. 8e, the indoor temperature distribution of the continuous control method of the angular velocity of the wind guide vane in the cooling mode according to the present embodiment is more uniform, and the comfort of the user is improved.

In one embodiment, the angular velocity of the air guide blade varies within ± 50% of the average angular velocity, and when the angular velocity of the air guide blade is controlled to improve the comfort of the air conditioner, the rate of change of the angular velocity of the air guide blade may be greater than 20% and less than 50% (i.e., the difference between the angular velocities of the adjacent operation stages is from 20% of the average angular velocity to 50% of the average angular velocity). The present embodiment provides a condition of proportional change of an insufficient air flow region of an indoor air conditioner (i.e., a region where an indoor temperature is above 30 degrees in a cooling mode) of a wind guide blade under different angular velocity change rates, see a proportional relationship diagram between the angular velocity change rate and the insufficient region in the cooling mode as shown in fig. 10a, and it can be seen from fig. 10a that the larger the angular velocity change rate is, the more uniform the indoor temperature is, when the angular velocity change rate is greater than 20%, the insufficient air flow region ratio is obviously decreased, the smaller the insufficient air flow region ratio of the air conditioner is, the more uniform the indoor temperature distribution is indicated, the better the air-conditioning cooling effect is, and when the angular velocity change rate reaches 50%, the insufficient air flow region ratio is basically saturated, therefore, when the angular velocity change rate of the wind guide blade is greater than 20% and less than 50%, the indoor temperature distribution can be obviously made more uniform, and the comfort of the air conditioner is improved.

In order to verify and compare the control effects of the angular velocities in the 2-operation phase, the 3-operation phase and the continuous control mode, the present embodiment provides a relationship diagram of the ratio of insufficient air-conditioning airflow areas in the 2-operation phase control mode in fig. 5b, the 3-operation phase control mode in fig. 6b and the continuous control mode in fig. 9a under the cooling mode, see the trend chart of the change of the ratio of insufficient air-conditioning airflow areas under different angular velocity control modes shown in fig. 10b, and for obvious comparison, fig. 10b also shows the ratio of insufficient air-conditioning airflow areas corresponding to the angular velocity in the constant value control mode in fig. 8a, and the ratio of insufficient air-conditioning airflow areas corresponding to the angular velocity in the constant value control mode is significantly higher than the ratio of insufficient air-conditioning airflow areas under the continuous control mode, the 3-phase control mode and the 2-phase control mode in the present application, so that the angular velocity 2-operation phase control mode in the present application, And 3, the control mode and the continuous control mode at the operation stage obviously improve the heating and refrigerating comfort of the air conditioner.
