By adopting the control method for the air conditioner air guide provided by the embodiment of the disclosure, the temperature of the air guide plate of the air conditioner is obtained, and the dew point temperature of the leeward surface area of the air guide plate is determined, the root cause of condensation generated on the leeward surface of the air guide plate is that the temperature of the air guide plate is lower than the dew point temperature of the air in the leeward surface area of the air guide plate, so that water in the air guide plate in the leeward surface area is condensed into water drops to be adsorbed on the leeward surface of the air guide plate, whether the air guide plate reaches the dew point condition is more accurate is judged according to the temperature difference interval of the temperature difference of the air guide plate and the dew point temperature, the opening or closing of the air guide plate is controlled, the cold air flow is better guided to the leeward surface of the air guide plate through the air guide plate, the air guide performance of the air guide plate is not required to be sacrificed under the assistance of the air guide plate, the generation of the condensation of the air guide plate is reduced while the air guide effect of the air guide plate is not influenced, and the air supply comfort is improved.
Optionally, a temperature sensor is arranged on the leeward side of the air deflector, and the temperature sensor is arranged in the middle area of the leeward side of the air deflector. Therefore, the temperature of the lee surface of the air deflector is detected in real time through the temperature sensor, the detected temperature sent by the temperature sensor is obtained by the processor to serve as the temperature of the air deflector, and the lee surface of the air deflector is in contact with external hot air, so that condensation is easy to occur, the temperature of the lee surface of the air deflector is obtained by the processor to serve as the temperature of the air deflector, the state of the air deflector is controlled according to the temperature difference between the temperature of the air deflector and the dew point temperature, and the accuracy of condensation judgment of the air deflector is further improved.
Specifically, the temperature sensors can be arranged in a plurality, the temperature sensors are uniformly distributed on the lee surface of the air deflector, and the processor acquires a plurality of temperatures detected by the temperature sensors and determines the average value of the temperatures as the temperature of the air deflector. Like this, through set up a plurality of evenly distributed's temperature sensor in the lee face of aviation baffle, detect the temperature in a plurality of regions of lee face of aviation baffle simultaneously to confirm the average value in the temperature in a plurality of regions and regard as the aviation baffle temperature, further improved the acquisition precision of aviation baffle temperature, more accurate temperature difference according to aviation baffle temperature and dew point temperature comes the state of control aviation baffle.
In some embodiments, the processor determines a dew point temperature of a lee side region of the air deflection plate, comprising: the processor obtains the dry bulb temperature of the lee surface area of the air deflector, and determines the dew point temperature according to the dry bulb temperature. Therefore, the processor determines the dew point temperature according to the dry ball temperature by acquiring the dry ball temperature of the lee surface area of the air deflector, and improves the accuracy of dew point temperature acquisition, so that the state of the air deflector is controlled more accurately according to the temperature difference between the air deflector temperature and the dew point temperature.
Optionally, a dry bulb temperature sensor is also arranged in the lee surface area of the air deflector. Therefore, the dry bulb temperature sensor is used for detecting the dry bulb temperature of the lee surface area of the air deflector, and the acquisition process of the dry bulb temperature is simplified.
Optionally, the processor determines the dew point temperature from the dry bulb temperature, comprising: the processor determines saturated water vapor pressure corresponding to the dry bulb temperature according to the dry bulb temperature, and determines dew point temperature according to the saturated water vapor pressure. Thus, the accuracy of the dew point temperature is improved, and the state of the air guide plate is controlled more accurately according to the temperature difference between the air guide plate temperature and the dew point temperature.
Specifically, the processor determines the saturated water vapor pressure corresponding to the dry bulb temperature according to the dry bulb temperature through the following formula:
Units: MPa (MPa)
Wherein t is the dry bulb temperature, and Ps is the saturated water vapor pressure.
Specifically, the processor determines the dew point temperature from the saturated water vapor pressure by the following formula:
y= 21.348ln (Ps) +146.02 units: DEG C
Wherein y is dew point temperature, and Ps is saturated water vapor pressure.
It can be appreciated that the above formulas are all codes written into the processor database, and when the processor acquires the dry bulb temperature, the above formulas are directly called to calculate the dew point temperature.
In some embodiments, the processor controls the opening or closing of the air induction plate of the air conditioner according to a temperature difference interval in which the temperature difference is located, including: the processor controls the air inducing plate of the air conditioner to be opened under the condition that the temperature difference is in a first temperature difference range; the processor controls the air inducing plate of the air conditioner to be closed under the condition that the temperature difference is in a second temperature difference range; wherein the maximum value in the first temperature difference interval is smaller than the minimum value in the second temperature difference interval. In this way, the maximum value in the first temperature difference interval is smaller than the minimum value in the second temperature difference interval, when the temperature difference is in the first temperature difference interval, the temperature difference between the air deflector temperature and the dew point temperature is smaller, namely, the air deflector temperature is close to the dew point temperature, and the risk of condensation exists on the leeward side of the air deflector at the moment, so that the processor controls the air guiding plate of the air conditioner to be opened, the leeward side of the air deflector in the air duct main body is utilized by the air guiding plate, the dew point temperature in the leeward side area of the air deflector is reduced, the temperature difference between the air deflector temperature and the dew point temperature is further increased, the occurrence of condensation is reduced, when the temperature difference is in the second temperature difference interval, the temperature difference between the air deflector temperature and the dew point temperature is larger, namely, the air deflector temperature is higher than the dew point temperature, and the risk of condensation on the leeward side of the air deflector is lower, so that the air guiding plate of the air conditioner is controlled by the processor to be closed, the leeward side of the air deflector in the air duct main body is not required to be blown out of the leeward side of the air deflector, and the air flow is cooled, and the windward side effect of the air deflector is improved.
Specifically, the first temperature difference interval is an interval of less than or equal to 3 ℃, and the second temperature difference interval is an interval of more than 3 ℃. Like this, when the temperature difference between aviation baffle temperature and the dew point temperature is in first temperature difference interval, namely the temperature difference between aviation baffle temperature and the dew point temperature is less than or equal to 3 ℃, there is the risk of condensation in the leeward face of aviation baffle this moment, and when the temperature difference between aviation baffle temperature and the dew point temperature is in second temperature difference interval, namely the temperature difference between aviation baffle temperature and the dew point temperature is greater than 3 ℃, and the risk of condensation of leeward face of aviation baffle this moment is lower, steerable air guide plate closes.
It can be understood that controlling the air guiding plate to close means controlling the air guiding plate to recover to an initial position, namely, a position where the air guiding plate is attached to the inner wall of the air duct main body, if the air guiding plate is at the initial position, the air guiding plate is controlled to be not operated, and if the air guiding plate moves to the air guiding position, the air guiding plate is controlled to recover to the initial position.
As shown in conjunction with fig. 2, in some alternative embodiments, a control method for air guiding of an air conditioner includes:
s01, a processor acquires the temperature of an air deflector of the air conditioner;
S02, the processor determines the dew point temperature of the lee surface area of the air deflector;
s03, determining a temperature difference between the temperature of the air deflector and the dew point temperature by the processor;
S041, the processor controls the air inducing plate of the air conditioner to be opened under the condition that the temperature difference is in a first temperature difference interval;
s05, the processor acquires the motion state of the air deflector, and controls the motion state of the air deflector according to the motion state of the air deflector.
By adopting the control method for the air conditioner air guide provided by the embodiment of the disclosure, when the temperature difference is in the first temperature difference range, the temperature difference between the temperature of the air guide plate and the dew point temperature is smaller, so that the air guide plate of the air conditioner is controlled to be opened to guide cold air flow, part of the cold air flow is blown to the leeward side of the air guide plate, the processor also needs to acquire the motion state of the air guide plate, and the motion state of the air guide plate is controlled according to the motion state of the air guide plate, so that the cold air flow guided by the air guide plate can always be blown to the leeward side area of the air guide plate, the air flow guiding effect of the air guide plate is guaranteed, and the condensation risk of the air guide plate is further reduced.
Optionally, the processor acquires a motion state of the air deflector, including: the processor obtains the working state of the air deflector motor, and determines the motion state of the air deflector according to the working state of the air deflector motor, wherein the working state of the air deflector motor is rotation and stop. Therefore, the motion of the air deflector depends on the driving of the air deflector motor, and the processor determines the motion state of the air deflector by acquiring the working state of the air deflector motor to rotate or stop, so that the accuracy of the determined motion state of the air deflector is improved.
Specifically, the processor obtains the operating condition of aviation baffle motor, confirms the motion state of aviation baffle according to the operating condition of aviation baffle motor, includes: when the obtained working state of the air deflector motor is rotation, the processor determines that the motion state of the air deflector is rotation; when the processor acquires that the working state of the air deflector motor is stopped, the processor determines that the motion state of the air deflector is stationary. Therefore, the motion of the air deflector depends on the driving of the air deflector motor, when the working state of the air deflector motor acquired by the processor is rotation, the air deflector is also in a rotation state under the driving action of the air deflector motor, so that the motion state of the air deflector is determined to be rotation, and when the working state of the air deflector motor acquired by the processor is stop, the air deflector is not driven by the air deflector motor, so that the motion state of the air deflector is determined to be static.
Optionally, the processor acquires a motion state of the air deflector, and controls the motion state of the air deflector according to the motion state of the air deflector, including: the processor controls the motion state of the air deflector to be static under the condition that the motion state of the air deflector is static; and the processor controls the motion state of the air deflector to rotate under the condition that the motion state of the air deflector rotates. Therefore, when the processor determines that the motion state of the air deflector is static, the air deflector is at a fixed opening angle to conduct air deflection, so that the motion state of the air deflector is still, namely, the air deflector is controlled to conduct air deflection at the fixed opening angle, part of cold air flow is guided to blow the leeward surface area of the air deflector, when the processor determines that the motion state of the air deflector is rotating, the air deflector is in a continuously rotating air deflection state, if the air deflector is controlled to conduct air deflection at the fixed angle, the air flow of the leeward surface area of the air deflector is greatly changed along with the change of the rotating position of the air deflector, the anti-condensation effect is poor, and therefore, the motion state of the air deflector is controlled to rotate, the air deflector is enabled to continuously rotate along with the air deflector, and the air deflector always keeps good air deflection effect.
As shown in conjunction with fig. 3, in some alternative embodiments, a control method for air guiding of an air conditioner includes:
s01, a processor acquires the temperature of an air deflector of the air conditioner;
S02, the processor determines the dew point temperature of the lee surface area of the air deflector;
s03, determining a temperature difference between the temperature of the air deflector and the dew point temperature by the processor;
S041, the processor controls the air inducing plate of the air conditioner to be opened under the condition that the temperature difference is in a first temperature difference interval;
S051, controlling the motion state of the air guide plate to be static by the processor under the condition that the motion state of the air guide plate is static;
and S051-1, the processor acquires the opening angle of the air deflector, determines the target opening angle of the air deflector according to the opening angle of the air deflector, and controls the air deflector to be opened to the target opening angle and then to be kept in a static state.
By adopting the control method for air conditioner air guide provided by the embodiment of the disclosure, the processor is used for controlling the air guide plate to open and guide cold air flow under the condition that the temperature difference is determined to be in the first temperature difference range, at the moment, the condensation risk of the leeward side of the air guide plate is larger, under the condition that the motion state of the air guide plate is determined to be static, the opening angle of the air guide plate is obtained, the target opening angle of the air guide plate is determined according to the opening angle of the air guide plate, then the air guide plate is controlled to be opened to the target opening angle and then kept static, the cold air flow is guided by the air guide plate, the better leeward side area of the cold air flow is blown, the condensation risk of the leeward side of the air guide plate is reduced, because the opening angles of the leeward side of the air guide plate are different, the cold air flow in the air channel main body can flow to the leeward side of the air guide plate when the opening angle of the air guide plate is larger, the air guide plate is required to be smaller, the leeward side of the air guide plate is opened when the opening angle of the air guide plate is smaller, the leeward side of the air guide plate is opened, the air flow in the air guide plate is opened by the larger, and the air guide plate is opened by the air guide plate, and the air flow is blown out of the air guide plate.
It will be appreciated that the opening angle of the air deflector is the angle between the connecting line of the upper end and the lower end of the air deflector and the horizontal direction, and the opening angle of the air deflector is the angle between the connecting line of the upper end and the lower end of the air deflector and the side wall of the air duct main body.
Specifically, the opening angle of the air deflector and the target opening angle of the air deflector have a corresponding relationship, the corresponding relationship between the opening angle of the air deflector and the target opening angle of the air deflector can be pre-stored in a database of the processor, and when the opening angle of the air deflector is determined by the processor, the target opening angle of the air deflector can be determined according to the corresponding relationship. For example, when the opening angle of the air deflector is 20 degrees, the target opening angle of the corresponding air deflector is 15 degrees; when the opening angle of the air deflector is 30 degrees, the target opening angle of the corresponding air deflector is 10 degrees; when the opening angle of the air deflector is 45 degrees, the target opening angle of the corresponding air deflector is 5 degrees.
As shown in conjunction with fig. 4, in some alternative embodiments, a control method for air guiding of an air conditioner includes:
s01, a processor acquires the temperature of an air deflector of the air conditioner;
S02, the processor determines the dew point temperature of the lee surface area of the air deflector;
s03, determining a temperature difference between the temperature of the air deflector and the dew point temperature by the processor;
S041, the processor controls the air inducing plate of the air conditioner to be opened under the condition that the temperature difference is in a first temperature difference interval;
S052, under the condition that the motion state of the air deflector rotates, the processor controls the motion state of the air deflector to rotate;
S052-1, the processor controls the air deflector to rotate to a first position, and obtains the rotating position of the air deflector;
s052-2, under the condition that the air deflector rotates to a target position, the processor acquires the rotation angle of the air deflector within a preset time period;
S052-3, the processor determines a target rotation angle of the air guide plate within a preset time period according to the rotation angle of the air guide plate, and controls the air guide plate to rotate along with the air guide plate in a mode of rotating the target rotation angle within the preset time period.
By adopting the control method for the air conditioner air guide provided by the embodiment of the invention, when the processor determines that the temperature difference between the temperature of the air guide plate and the dew point temperature is in the first temperature difference interval, the temperature difference between the temperature of the air guide plate and the dew point temperature is smaller at the moment, the air guide plate is required to be controlled to be opened to guide air flow on the leeward side of the air guide plate, so as to ensure the air guide effect of the air guide plate, the processor acquires the motion state of the air guide plate again, and under the condition that the motion state of the air guide plate is rotating, the motion state of the air guide plate is also rotating, so that the air guide plate rotates along with the air guide plate, but because the temperature difference between the temperature of the air guide plate and the dew point temperature is acquired in real time, if the air guide plate and the air guide plate are both in the rotation limit position, the rotation of the air guide plate is controlled to be limited, or the rotation of the air guide plate is caused to be different from the current air guide requirement along with the rotation change, and the air guide plate is controlled to rotate along with the rotation of the air guide plate; and because the rotating speeds of the air deflectors are different, the rotating speeds of the air deflectors along with the rotating speeds of the air deflectors are also different, so that the processor obtains the rotating angle of the air deflectors in the preset time period under the condition that the air deflectors rotate to the target positions, namely the rotating angle of the air deflectors in the preset time period, determines the target rotating angle of the air deflectors corresponding to the rotating angle of the air deflectors in the preset time period according to the rotating angle of the air deflectors in the preset time period, controls the air deflectors to rotate along with the air deflectors at the rotating speed of the target rotating angle in the preset time period, enables the air quantity to be better matched with the rotating angle of the air deflectors everywhere, and further reduces the condensation risk of leeward surfaces of the air deflectors.
Optionally, the first position of the air guiding plate is a middle position between the lower rotation limit position and the upper rotation limit position of the air guiding plate, and the target position of the air guiding plate is a middle position between the lower rotation limit position and the upper rotation limit position of the air guiding plate. Therefore, the air guide plate and the air guide plate are provided with rotation allowance upwards or downwards, and the air guide plate better guides the cold air flow to the leeward surface of the air guide plate when rotating along with the air guide plate.
Specifically, the lower rotation limit position of the air guiding plate is a position where the included angle between the connecting line of the upper end and the lower end of the air guiding plate and the side wall of the air duct main body is 0 degrees, namely, the air guiding plate is attached to the closed position of the side wall of the air duct main body, the upper rotation limit position of the air guiding plate is a position where the included angle between the connecting line of the upper end and the lower end of the air guiding plate and the side wall of the air duct main body is 30 degrees, and the first position of the air guiding plate is a position where the included angle between the connecting line of the upper end and the lower end of the air guiding plate and the side wall of the air duct main body is 15 degrees (as shown in fig. 5, the angle A in the figure is the included angle between the connecting line of the upper end and the lower end of the air guiding plate and the side wall of the air duct main body when the air guiding plate is located at the first position); the lower rotation extreme position of aviation baffle is the position that the contained angle between upper and lower end line and the vertical direction of aviation baffle is 0 degrees, and the upper and lower end line of aviation baffle is parallel with the vertical direction promptly, and the upper rotation extreme position of aviation baffle is the position that the contained angle between upper and lower end line and the vertical direction of aviation baffle is 90 degrees, and the upper and lower end line and the vertical direction of aviation baffle promptly are perpendicular, and the target position of aviation baffle is the position that the contained angle between upper and lower end line and the vertical direction of aviation baffle is 45 degrees (as shown in fig. 6, angle B is the contained angle between the upper and lower end line and the vertical direction of aviation baffle when the aviation baffle is located the target position in the figure). Therefore, when the processor determines that the motion state of the air deflector is rotation, the air deflector is controlled to rotate to a first position, namely, the air deflector is controlled to rotate to a position where the included angle between the upper end connecting line and the lower end connecting line of the air deflector and the side wall of the air duct main body is 15 degrees, so that the air deflector has 15-degree rotation allowance no matter upwards or downwards, the air deflector is controlled to rotate along with the air deflector when the air deflector rotates to a target position, the included angle between the upper end connecting line and the lower end connecting line of the air deflector and the vertical direction is 45 degrees when the air deflector rotates to the target position, the air deflector has 45-degree rotation allowance no matter upwards or downwards, and therefore, the drainage amount of the air deflector is changed along with the change of the rotation angle of the air deflector better, and the adaptation of the drainage amount and the rotation position of the air deflector is maintained.
Optionally, under the condition that the air guiding plate is located at the first position and the air guiding plate is located at the target position, an included angle between the connecting line of the upper end and the lower end of the air guiding plate and the connecting line of the upper end and the lower end of the air guiding plate is 90 degrees. Therefore, when the air guiding plate is positioned at the first position and the air guiding plate is positioned at the target position, the air guiding plate and the air guiding plate are mutually perpendicular, and then the air guiding plate is controlled to rotate along with the air guiding plate, so that the air guiding amount of the air guiding plate is better matched with the rotating position of the air guiding plate.
Specifically, the preset duration is 10 seconds, the processor obtains the rotation angle of the air deflector within 10 seconds to be 30 degrees, determines the target rotation angle of the air deflector within 10 seconds to be 10 degrees according to the rotation angle of the air deflector within 10 seconds, and controls the air deflector to rotate along with the air deflector at a speed of 10 degrees in 10 seconds. Therefore, the rotating speed of the air deflector can be reflected by 30 degrees of rotation of the air deflector in 10 seconds, and the rotating angle of the air deflector rotating from the lower rotating limit position to the upper rotating limit position is 90 degrees, and the rotating angle of the air deflector rotating from the lower rotating limit position to the upper rotating limit position is 30 degrees.
It can be understood that the rotation angle of the air deflector and the air guiding plate can be in other ranges, and can be determined according to the actual rotation angle of the air deflector and the air guiding plate of the air conditioner.
Optionally, controlling the air guiding plate to rotate along with the air guiding plate comprises: the air guiding plate is controlled to rotate along with the air guiding plate in the direction opposite to the rotating direction of the air guiding plate. Therefore, the air guide plate gradually reduces the overflow surface formed between the leeward surface and the air duct main body when rotating clockwise, the overflow surface formed between the leeward surface and the air duct main body when rotating anticlockwise is gradually increased, the air guide plate gradually reduces the air guide amount when rotating anticlockwise, the air guide amount is gradually increased when rotating anticlockwise, in order to ensure that the air guide amount of the air guide plate is always matched with the rotating position of the air guide plate, when the air guide plate is positioned at a first position and the air guide plate rotates to a target position, the air guide plate is controlled to rotate along with the air guide plate in the direction opposite to the rotating direction of the air guide plate, so that the air guide amount of the air guide plate is always matched with the rotating position of the air guide plate, the cold air flow is blown to the leeward surface of the air guide plate through the guide of the air guide plate, and the condensation risk of the leeward surface of the air guide plate is reduced.

According to the air conditioner provided by the embodiment of the disclosure, heat exchange airflow flows in the air duct main body 200 and is blown out from the air outlet 210, the air outlet airflow at the air outlet 210 is guided by the air deflector 220, the temperature of the air deflector 220 is lower due to the contact of the air deflector 220 with the heat exchange airflow during refrigeration of the air conditioner, and condensation is caused on the leeward side due to the contact of the leeward side of the air deflector 220 with external hot air, so that air supply comfort is affected.
Alternatively, the air guiding plate 300 is rotatably disposed on a side wall of the air duct main body 200, and the side wall of the air duct main body 200 is a side wall of the air duct main body 200 towards which the windward side of the air guiding plate 220 faces in the open state. In this way, the air guiding plate 300 can be installed in a hidden manner, the air guiding plate 300 can be attached to the side wall of the air duct main body 200 when the cold air flow is not required to be guided, the influence of the air guiding plate 300 on the air outlet air flow is reduced, and when the cold air flow is required to be guided, the air guiding plate 300 is controlled to be opened towards the leeward side of the air guiding plate 220, and the air flow is guided.
