The shell 4 is provided with an air outlet, an air channel is arranged in the shell 4, and the air channel is communicated with the air outlet. The cyclone air dispersing module 1 is movably arranged at the edge of the air outlet and can be an upper side, a lower side, a left side or a right side. In other embodiments, the air conditioner may not be provided with the first air deflector 2 and the second air deflector 3.
Specifically, in this embodiment, the first air deflector 2 is disposed in the air duct, the second air deflector 3 is movably disposed at the lower side of the air outlet, and the cyclone air dispersing module 1 is movably disposed at the upper side of the air outlet. The second air deflector 3 is provided with a plurality of ventilation holes, and air flow in the air duct can flow out in a dispersed manner in the plurality of ventilation holes.
The cyclone air dispersing module 1 specifically comprises a rotatable rotary blade assembly, and the air flow reaching the air outlet in the air duct is blown away by the rotation of the rotary blade assembly and then is sent into an indoor environment.

When the position of the second air deflector 3 is fixed, the sliding positions of the cyclone air dispersing modules 1 are different, and then the interval distances between the cyclone air dispersing modules 1 and the second air deflector 3 are different. In other embodiments, when the air outlet is not provided with the second air deflector 3, the cyclone air-dispersing module 1 may also be moved at different positions with respect to the edge of the air outlet on the opposite side of the air outlet from the installation side of the cyclone air-dispersing module 1, so as to achieve partial or complete shielding of the air outlet.

Specifically, the first air deflector 2 may have different air guiding positions, and the air volume, the air direction, etc. of the air outlet in the air duct may be adjusted at the different air guiding positions. For example, when the first air deflector 2 is parallel to the air flow direction in the air duct, the air outlet has the maximum air outlet, when the first air deflector 2 is perpendicular to the air flow direction in the air duct, the air outlet has the minimum air outlet, and when the first air deflector 2 is intersected with the air flow direction in the air duct and is not perpendicular to the air flow direction in the air duct, the air outlet of the air outlet is positioned between the maximum air outlet and the minimum air outlet.

The rotating piece is connected with the first rotating blade assembly, so that the first rotating blade assembly can rotate under the drive of the rotating piece. The number of the first blades and the number of the second blades may be set to be the same or different according to actual demands.
The first rotary vane assembly can be provided with a limiting piece matched with the first rotary vane assembly, and when the first rotary vane assembly rotates, the second rotary vane assembly can also synchronously rotate under the drive of the limiting piece of the first rotary vane assembly.

Referring to fig. 4, an embodiment of a control method of an air conditioner according to the present application is provided. In this embodiment, the control method of the air conditioner includes:
step S10, acquiring an ambient temperature parameter and an ambient humidity parameter;
The environmental temperature parameter specifically refers to a parameter representing the indoor environmental temperature condition, and may be data directly detected by a temperature sensor arranged in the indoor environment, or may be data obtained by further processing the data detected by the temperature sensor. The ambient temperature parameter may specifically include an ambient temperature value and/or a temperature variation parameter (e.g., a temperature variation amplitude, a temperature variation rate, a temperature variation trend, a temperature variation curve, etc.).
The environmental humidity parameter specifically refers to a parameter representing the current humidity condition of the indoor environment, and may be data directly detected by a humidity sensor arranged in the indoor environment, or may be data obtained by further processing the data detected by the humidity sensor. The environmental humidity parameter may specifically include an environmental humidity value and/or a humidity variation parameter (e.g., a humidity variation amplitude, a humidity variation rate, a humidity variation trend, a humidity variation curve, etc.).
Specifically, when the air conditioner is in the cooling operation, if a set wind sense instruction (such as an instruction for reducing wind sense, an instruction without wind sense or an instruction with soft wind sense) is received, the air conditioner can be controlled to enter a set wind sense mode. In the set wind sense mode, step S10 may be performed.
Step S20, determining a wind-dispersing control parameter of the rotational flow wind-dispersing module and a wind guiding position of the first wind deflector according to the environmental temperature parameter and the environmental humidity parameter;
The air-dispersing control parameter is specifically an operation parameter related to the regulation effect of the cyclone air-dispersing module on air outlet parameters such as air quantity and air direction of an air outlet. The wind-dispersing control parameters specifically comprise a wind-shielding position (such as a position where an air outlet is partially blocked or a position where the air outlet is completely blocked) of the cyclone wind-dispersing module, a ventilation area of the cyclone wind-dispersing module, a position parameter of a rotary vane in the cyclone wind-dispersing module, a rotary speed of the rotary vane in the cyclone wind-dispersing module and the like.
The air guiding position specifically refers to the position of the first air guiding plate in the air duct relative to the air flow direction in the air duct. The air guide position specifically comprises a position where the first air guide plate is intersected with or parallel to the air flow direction in the air duct. The position where the first air deflector intersects with the air flow direction in the air duct may further include a position where the first air deflector intersects with the air flow direction in the air duct perpendicularly or does not intersect perpendicularly (for example, a position where one side of the first air deflector close to the air outlet is higher than one side of the first air deflector far away from the air outlet or a position where one side of the first air deflector close to the air outlet is lower than one side of the first air deflector far away from the air outlet). The air flow direction of the air flow in the air duct blowing to the air outlet is different at different air guiding positions, and even the air quantity reaching the air outlet is different. When the air outlet is simultaneously provided with the second air deflector and the rotational flow air dispersing module, the air guiding position of the first air deflector can adjust the proportion of the air outlet at the air outlet of the second air deflector and the rotational flow air dispersing module.
Different environmental temperature parameters and different environmental humidity parameters correspond to different air-dispersing control parameters and air-guiding positions. Specifically, different environmental temperature parameters and different environmental humidity parameters correspond to air volume intervals which are required to be reached by different air volumes required by condensation prevention, and corresponding air distribution control parameters and air guiding positions can be determined based on the air volume intervals, so that the determined air distribution control parameters and the determined air guiding positions can be matched to enable the air volume of the air conditioner to reach the condensation prevention condition. Based on the above, the corresponding relation between the environmental temperature parameter and the environmental humidity parameter, the air-dispersing control parameter and the air guiding position can be established in advance. The correspondence may be a calculation relationship, a mapping relationship, or the like. Based on the corresponding relation, the air-dispersing control parameter and the air-guiding position corresponding to the current environmental temperature parameter and the environmental humidity parameter can be determined.
And S30, controlling the rotational flow air dispersing module to at least partially shade the air outlet according to the air dispersing control parameter, and controlling the first air deflector to guide air at the air guiding position, wherein the rotational flow air dispersing module and the first air deflector are matched, and the air quantity of the air outlet reaches the condensation preventing condition.
The cyclone air dispersing module at least partially shields the air outlet, and particularly comprises the cyclone air dispersing module and the air outlet edge or an air guide plate arranged on the air outlet edge, wherein the air outlet is sealed in a matched manner, and the cyclone air dispersing module and the air outlet edge or the air guide plate arranged on the air outlet edge shield the air outlet. Specifically, when the cyclone air dispersing module partially shields the air outlet, part of air at the air outlet is dispersed by the air dispersing function of the cyclone air dispersing module and then is blown into the indoor environment, and the other part of air can be directly fed into the indoor environment without the air dispersing function; when the cyclone air dispersing module completely shields the air outlet, all air at the air outlet is blown into the indoor environment after being dispersed by the air dispersing function of the cyclone air dispersing module or the air dispersing function of the cyclone air dispersing module and other air guiding components.
According to the control method of the air conditioner, which is provided by the embodiment of the invention, the air conditioner is based on the air conditioner comprising the air deflector and the cyclone air dispersing module, wherein the air deflector is arranged in an air duct of the air conditioner, the cyclone air dispersing module is movably arranged at the edge of the air outlet, and the air dispersing control parameter of the cyclone air dispersing module and the air guiding position of the air deflector are determined through the ambient temperature parameter and the ambient humidity parameter.
Further, based on the above embodiment, another embodiment of the control method of the air conditioner of the present application is provided. In this embodiment, referring to fig. 5, the step S20 includes:
s21, determining the air-dispersing control parameter according to the environmental humidity parameter;
Different environmental humidity parameters correspond to different air-dispersing control parameters. Specifically, the larger the environmental humidity parameter is, the larger the air output of the air outlet corresponding to the air-dispersing control parameter is.
In this embodiment, the wind emission control parameter includes a wind shielding position of the cyclone wind emission module. Based on this, step S21 includes:
Step S211, determining a wind shielding position of the cyclone wind dispersing module according to the environmental humidity parameter; determining the wind break control parameter includes the wind break position.
Wherein, different environmental humidity parameters correspond to different wind shielding positions. Different wind blocking positions indicate different wind blocking areas of the cyclone wind dispersing module. The larger the wind shielding area is, the more airflow is sent into the indoor environment after the cyclone diffusion effect of the cyclone air dispersing module. Specifically, the wind shielding area corresponding to the wind shielding position tends to decrease with the increase of the environmental humidity parameter.
Specifically, in this embodiment, when the environmental humidity parameter is greater than a first set humidity threshold, the wind shielding position is determined to be a first wind shielding position; when the environmental humidity parameter is smaller than or equal to the first set humidity threshold value, determining the wind shielding position as a second wind shielding position; the wind shielding area corresponding to the first wind shielding position is smaller than the wind shielding area corresponding to the second wind shielding position. The specific size of the first set humidity threshold can be set according to actual conditions. In this embodiment, the first set humidity threshold is 70% in size. In other embodiments, the first set humidity threshold may be set to 75%, 80%, 65%, etc. according to actual needs. For example, the first set humidity threshold may be obtained based on a coil temperature of the indoor heat exchanger, the lower the coil temperature, the smaller the first set humidity threshold obtained. The first wind shielding position and the second wind shielding position can be positions for partially shielding the air outlet; or the first wind shielding position is a position for partially shielding the air outlet (for example, a position where the cyclone air dispersing module is arranged at intervals with the edge of the air outlet), and the second wind shielding position is a position for completely shielding the air outlet (for example, a position where the cyclone air dispersing module seals the edge of the air outlet). The cyclone air dispersing module adopts a smaller wind shielding area when the environmental humidity parameter is larger, so that part of the cyclone air dispersing module can at least partially diffuse air flow of the air outlet, and the air outlet quantity of the air outlet is increased, so that the air outlet quantity can meet the anti-condensation requirement; the cyclone air dispersing module adopts a larger wind shielding area when the environmental humidity parameter is smaller, so that the air dispersing and diffusing effect of the air outlet is increased, and the condensation possibility is relatively smaller at the moment, so that the air feeling comfort of indoor environmental users is improved while the condensation is not ensured.
Specifically, in this embodiment, the air conditioner further includes a second air deflector, the second air deflector is provided with a plurality of ventilation holes, the second air deflector is disposed at the lower side of the air outlet, the cyclone air dispersing module is disposed at the upper side of the air outlet, and before the step of controlling the cyclone air dispersing module to at least partially shield the air outlet according to the air dispersing control parameter, the air conditioner further includes: and controlling the second air deflector to move to a set position, wherein the set position is a position where the second air deflector completely opens the air outlet. On the basis, the first wind shielding position is a position (shown in fig. 6c and 6 f) at which the lower end of the cyclone wind dispersing module and the second wind deflector at the set position are arranged at intervals; the second wind blocking position is a position where the lower end of the cyclone wind dispersing module abuts against the second wind deflector at the set position and is matched with the second wind deflector at the set position to close the wind outlet (as shown in fig. 6a, 6b, 6d and 6 e). Here, shelter from the air outlet through the cooperation of second aviation baffle and the whirl wind module that is equipped with a plurality of ventilation holes, make in the wind channel blow to the air outlet air current partly can diffuse under the whirl effect of whirl wind module that looses, another part air current can be by the a plurality of ventilation holes of second aviation baffle to the area of air outlet air current diffusion has been increased, thereby ensures indoor environment user's wind sense travelling comfort when improving the air outlet air output.
In addition, in other embodiments, the edge of the air outlet or the position of the second air deflector when the air outlet is completely opened may be used as a reference position, and the interval distance between the lower side of the cyclone air-dispersing module and the reference position may be determined according to the environmental humidity parameter, where the interval distance tends to increase with the increase of the environmental humidity parameter.
And S22, determining the air guide position according to the environmental humidity parameter and the environmental temperature parameter.
Different ambient humidity parameters and different ambient temperature parameters correspond to different wind guiding positions. Specifically, the air flow direction in the air duct where the first air deflector is located is defined as a reference direction, the included angle between the first air deflector and the reference direction is defined as the air guiding angle of the first air deflector, and under the same environmental temperature parameter, the air guiding angle corresponding to the air guiding position is in a decreasing trend along with the increase of the environmental humidity parameter; under the same environmental humidity parameter, the wind guiding angle corresponding to the wind guiding position is in an increasing trend along with the increase of the environmental temperature parameter.
Specifically, in an embodiment, when the environmental temperature parameter is greater than or equal to a set temperature threshold, if the environmental humidity parameter is greater than the first set humidity threshold, determining the air guiding position as a first set position (as shown in fig. 6 c); when the environmental temperature parameter is greater than or equal to a set temperature threshold, if the environmental humidity parameter is less than or equal to the first set humidity threshold, determining the air guiding position as a second set position (as shown in fig. 6a and 6 b); the method comprises the steps of defining the air flow direction in an air duct where a first air deflector is located as a reference direction, defining an included angle between the first air deflector and the reference direction as an air guiding angle of the first air deflector, and enabling the air guiding angle corresponding to a first set position to be larger than the air guiding angle corresponding to a second set position.
Specifically, in another embodiment, when the environmental temperature parameter is smaller than the set temperature threshold, if the environmental humidity parameter is greater than the first set humidity threshold, determining the air guiding position as the second set position (as shown in fig. 6d and 6 e); when the environmental temperature parameter is less than the set temperature threshold, if the environmental humidity parameter is less than or equal to the first set humidity threshold, determining the air guiding position as the first set position (as shown in fig. 6 c).
Specifically, in this embodiment, the air guiding angle corresponding to the first setting position is 90 degrees, and the air guiding angle corresponding to the second setting position is 0.
The first set humidity threshold value here specifically refers to the same set humidity threshold value as the first set humidity threshold value of the wind blocking position of the cyclone wind-scattering module determined above. In addition, in other embodiments, the first set humidity threshold for determining the wind guiding position of the first wind guiding plate and the first set humidity threshold for determining the wind guiding position of the cyclone wind dispersing module may also refer to different set humidity thresholds according to actual situations. In addition, in other embodiments, the humidity interval corresponding to different air guiding positions of the first air guiding plate may be divided according to actual requirements by using different set humidity thresholds when the environmental temperature parameter is greater than or equal to the set temperature threshold, for example, the first set humidity threshold is used as the critical value of the humidity interval when the environmental temperature parameter is greater than or equal to the set temperature threshold, and the second set humidity threshold is used as the critical value of the humidity interval when the environmental temperature parameter is less than the set temperature threshold.
The set temperature threshold is specifically a temperature threshold for distinguishing the indoor environment temperature drop requirement. The specific value of the set temperature threshold can be set according to actual conditions, and the set temperature threshold can be a parameter set by a user or a parameter configured by default of the system. In this example, the temperature threshold was set at 26 ℃. In other embodiments, the set temperature threshold may also be set to 25 ℃, 27 ℃, 28 ℃, etc. as desired.
The environmental temperature parameter is greater than or equal to the settlement temperature threshold value, shows that the temperature drop demand is great at this moment, and on this basis, condensation possibility is less when humidity is lower, and the first aviation baffle adopts less wind guiding angle to carry out the wind-guiding this moment, guarantees that all air currents in the wind channel can reach the air outlet, and the position of keeping out the wind of cooperation whirlwind wind module has great area of keeping out the wind here to make the air conditioner can realize avoiding condensation phenomenon to produce, user's wind sense demand to satisfy and compromise when indoor environment temperature drops the effect. The condensation possibility is larger when the humidity is higher, the first air deflector is used for guiding air by adopting a larger air guiding angle, the wind shielding position of the cyclone air scattering module is matched with a smaller wind shielding area, the air flow in the air duct can effectively reduce the air quantity reaching the air outlet and reduce the air flow speed under the blocking or guiding action of the large air guiding angle of the first air deflector, the low-speed air flow reaching the air outlet on the basis can be blown out in a larger area which is not shielded by the cyclone air scattering module, meanwhile, the cold quantity reaching the air outlet can be reduced, the condensation phenomenon is avoided due to the fact that the temperature difference between the inner side and the outer side of the air outlet is larger, meanwhile, the wind speed felt by indoor users can be weakened due to the diffusion action of the cyclone air scattering module, and the air conditioner can achieve the effects of avoiding the condensation phenomenon, meeting the user wind sensing requirement and reducing the indoor environment temperature.
The environmental temperature parameter is less than the settlement temperature threshold value, indicate that the temperature drop demand is less this moment, on this basis, condensation possibility is less when humidity is lower, this moment first aviation baffle adopts great wind guide angle to carry out the wind guide, the amount of wind of blowing to the air outlet in the reducible wind channel, the position of keeping out the wind of cooperation cyclone wind module has great area of keeping out the wind here, guarantee that air outlet output cold volume can satisfy the temperature drop demand and further improve the diffusion effect of the air outlet air-conditioner of air conditioner simultaneously, realize user's wind sense travelling comfort's improvement, make the air conditioner can realize avoiding condensation phenomenon to produce, user's wind sense demand is satisfied and compromise when indoor environment temperature drops the effect. The condensation possibility is larger when the humidity is higher, at the moment, the first air deflector adopts a smaller air guide angle to guide air, the wind shielding position of the cyclone air scattering module is matched with a smaller wind shielding area, the air flow in the air duct can effectively increase the air outlet quantity of the air outlet under the action of the small air guide angle of the first air deflector, so that the temperature of the inner side and the outer side of the air outlet is further close to ensure that the condensation phenomenon is caused by larger temperature difference between the inner side and the outer side of the air outlet, and meanwhile, the wind speed felt by an indoor user can be weakened through the diffusion action of the cyclone air scattering module, so that the air conditioner can realize the effects of avoiding the condensation phenomenon, meeting the user wind sensing requirement and reducing the indoor environment temperature.
Based on the above, the air quantity blown to the air outlet in the air duct is larger when the humidity is larger, so that the air conditioner is ensured to have enough cold energy to cool the ambient air near the air outlet, and the condensation phenomenon caused by the temperature difference between the inside and the outside of the air outlet can be effectively avoided; and the air quantity of the air duct blowing to the air outlet is smaller when the humidity is smaller, the probability of condensation phenomenon is smaller at the moment, the first air deflector can realize the further improvement of the air conditioner windless effect at the wind shielding position, and the wind sensing comfort experience of a user is further improved.
In this embodiment, through the above steps S21 and S22, the air-dispersing control parameter of the air-dispersing module (such as the wind-shielding position of the air-dispersing module) is determined based on the humidity condition of the indoor environment, so as to adjust the air-dispersing range of the air outlet by the air-dispersing module, ensure that the air-dispersing module can make the air flow send into the room after the air outlet is diffused and avoid the too small air quantity of the air outlet, and on this basis, adjust the wind-guiding position of the first wind deflector in combination with the temperature and humidity of the indoor environment, so as to realize that the wind-dispersing control parameter such as the wind-shielding position of the air-dispersing module and the wind-guiding position can cooperate to realize avoiding the condensation phenomenon, meeting the user' S wind-sensing requirement and giving consideration to the indoor environment temperature-reducing effect.
In addition, in another embodiment, the first air deflector may be rotatably installed in the air duct through a rotating shaft, and a position where the lower end of the cyclone air dispersing module corresponding to the wind shielding position of the cyclone air dispersing module corresponding to the current environmental temperature parameter and/or the environmental humidity parameter is located is defined as a target position, based on this, the second set position may also be a position where the free end of the first air deflector extends towards the target position, and the first set position may be any position where the air guiding angle is greater than the second set position herein. Based on this, no matter the cyclone air-out module is in part or all shelters from the air outlet, guarantees as far as possible that the air-out of air outlet passes through the cyclone air-out module cyclone air-out and carries out the diffusion back and send into indoor again when increasing the air outlet amount to guarantee that the air-out can satisfy the air-out comfort of indoor environment user when preventing the condensation demand. The free end of the first air deflector in the air channel can be arranged at intervals with the cyclone air dispersing module and/or a plurality of ventilation openings are formed in the first air deflector, so that air in the air channel is blown to the air outlet after being dispersed by the first air deflector, or the air in the air channel is led to change the direction of the air flow for a plurality of times through the guiding action of a gap between the free end and the cyclone air dispersing module so as to reduce the wind speed, and then the air is sent into a room from the gap between the lower end of the cyclone air dispersing module and the edge of the air outlet or the second air deflector. Through this mode setting, can include that the air current in the wind channel can send into indoor from the air outlet after dispelling wind or slowing down to avoid the air current in the wind channel to blow the user directly to guarantee user's travelling comfort.
Further, in the foregoing embodiment, the cyclone wind dispersing module includes a first vane assembly and a second vane assembly that are disposed at intervals in a flow direction of air, the first vane assembly is rotatable with respect to the second vane assembly, the second vane assembly includes a plurality of second vanes disposed at intervals in a circumferential direction, the first vane assembly includes a plurality of first vanes disposed at intervals in the circumferential direction, and the wind dispersing control parameter further includes a target relative position of the first vanes and the second vanes when the cyclone wind dispersing module rotates, based on which, step S21 may further include:
Step S212, determining a target relative position according to the environmental humidity parameter; the target relative position is the relative position of the first blade and the second blade when the rotational flow wind dispersing module operates; determining the ventilation control parameter includes the target relative position.
It should be noted that, the step S21 may include one of the steps S211 and S212 or both of the two sub-steps S211 and S212 according to actual requirements. In the case where step S21 includes both step S211 and step S212, the order of execution of the two steps is not particularly limited.
Different ambient humidity parameters correspond to different target relative positions. And if the relative positions of the targets are different, the wind dispersing effect and the wind output corresponding to the rotational flow wind dispersing module are different. Specifically, the larger the environmental humidity parameter is, the larger the air output corresponding to the target relative position is.
In this embodiment, the target relative position includes a position where the first blade and the second blade are disposed in a staggered manner and a position where the first blade and the second blade are disposed in a aligned manner. Specifically, when the environmental humidity parameter is less than or equal to a second set humidity threshold, determining the target relative position as a position where the first blade and the second blade are arranged in a staggered manner (as shown in fig. 6a and 6 d); and when the environmental humidity parameter is greater than the second set humidity threshold, determining the target relative position as a position where the first blade and the second blade are aligned (as shown in fig. 6b, 6c, 6e and 6 f). The second set humidity threshold is less than the first set humidity threshold. The specific value of the second set humidity threshold can be set according to actual requirements. In this embodiment, the second set humidity threshold is specifically 40%. In other embodiments, the second set humidity threshold may also be set to 45%, 50%, 35%, etc. according to actual requirements. For example, the second set humidity threshold may be obtained based on the coil temperature of the indoor heat exchanger, with the lower the coil temperature, the lower the second set humidity threshold obtained.
In addition, in other embodiments, the target relative position may further include a position where the first blade and the second blade are disposed at a plurality of different angles. Based on the above, the included angle between the first blade and the second blade tends to decrease with the increase of the environmental humidity parameter. For example, the target relative positions include a first position in which the angular bisectors of the first blade and the adjacent two second blades are aligned, a second position in which the edges of the first blade and the edges of the second blades are aligned, a third position in which the axes of the first blade and the second blades are aligned, and a fourth position in which the radial axes of the first blade and the angular bisectors of the adjacent two second blades are aligned. The environment humidity parameter is located in the first humidity interval, and the relative position of the target is determined to be a third position; the environmental humidity parameter is located in a second humidity interval, and the relative position of the target is determined to be a second position; the environmental humidity parameter is a third humidity interval, and the relative position of the target is determined to be a fourth position; and if the environmental humidity parameter is the fourth humidity interval, determining the relative position of the target as the first position. Wherein the first humidity interval is greater than the second humidity interval, the second humidity interval is greater than the third humidity interval, and the third humidity interval is greater than the fourth humidity interval.
In this embodiment, the relative position of two whirl vane assemblies when the whirl wind module rotates is determined based on the environmental humidity parameter, so that the air outlet of the air conditioner after the air is dispersed by the whirl wind module can be adapted to the indoor humidity condition for adjustment, the smaller air outlet is realized by the dislocation of the vanes when the humidity is smaller, the larger air outlet is realized by the alignment of the vanes when the humidity is larger, the cyclone wind module can be matched with the wind guiding action corresponding to the wind guiding position of the first wind guiding plate from the cyclone wind outlet, the air outlet of the air conditioner in a diffusion mode can be realized, the air outlet of the air conditioner can be matched with the air quantity required by the anti-condensation under the current humidity environment when the user air outlet comfort is ensured, and therefore, the user air feeling comfort and the anti-condensation requirement are realized.
When the air-dispersing control parameters simultaneously comprise a wind-shielding position corresponding to the cyclone air-dispersing module and a target relative position, and when the environmental humidity parameter is smaller than a second set humidity threshold value, the possibility of condensation is extremely low, the air outlet is completely shielded by the blade dislocation matched with the cyclone module, and the air outlet can be ensured to disperse air out of the air outlet and the air outlet corresponding to the cyclone air-dispersing module can be ensured to be minimum; when the environmental humidity parameter is larger than or equal to the second set humidity threshold value and smaller than the first set humidity threshold value, the condensation possibility is higher, the air outlet is completely shielded by the blade alignment matching cyclone module based on the condensation possibility, the air outlet can be ensured to diffuse and output air, and the air output corresponding to the cyclone air-dispersing module can reach medium air output; when the environmental humidity parameter is greater than or equal to the first set humidity threshold value, the condensation possibility is extremely high, the air outlet is partially shielded by the blade alignment matching cyclone module based on the condensation possibility, the air outlet can be ensured to diffuse air, and the air outlet corresponding to the cyclone air-dispersing module can reach the maximum air outlet. Based on the above, the larger the humidity is, the easier the condensation is, and the air output corresponding to the cyclone air-dispersing module is increased along with the increase of the humidity, so that the air output corresponding to the cyclone air-dispersing module is ensured to meet the condensation prevention requirement.
Further, in this embodiment, the environmental temperature parameter is defined as T, the above-mentioned set temperature threshold is Ts, the environmental humidity parameter is d, the above-mentioned first set humidity threshold is d1, and the above-mentioned second set humidity threshold is d2, based on which the wind blocking positions of the cyclone wind-dispersing modules, the relative positions of the two sets of blades of the cyclone wind-dispersing modules, and the wind guiding positions of the first wind deflector corresponding to different environmental temperature parameters and different environmental humidity parameters can be specifically seen in fig. 6.
Further, based on any one of the above embodiments, another embodiment of the control method of the air conditioner of the present application is provided. In this embodiment, referring to fig. 7, the control method of the air conditioner further includes the following steps:
step S100, obtaining a current environmental temperature value of an indoor environment;
The environmental temperature value here can be obtained by acquiring data detected by a temperature sensor provided in the indoor environment. The ambient temperature value in one embodiment may refer to the same parameter as the ambient temperature parameter in the above embodiment; in another embodiment, the ambient temperature value may refer to a different parameter than in the above embodiment, for example, the ambient temperature value may refer to a different parameter than here when the ambient temperature parameter is a parameter indicative of a temperature change.
Step S200, determining a target rotating speed of the fan according to the environmental temperature value and the set comfort temperature;
and step S300, controlling the fan to run according to the target rotating speed.

Based on the relation characteristic parameters of the environment temperature value and the set comfort temperature are determined; and determining the target rotating speed according to the relation characteristic parameters and the set rotating speed. The relation characteristic parameter is specifically a parameter representing the quantity relation characteristic between the environment temperature value and the set comfort temperature. The relation characteristic parameters comprise a difference value, a ratio and/or a mean value between the ambient temperature value and the set comfort temperature. The set rotating speed can be the rotating speed set by default of the system, can be the rotating speed set by a user based on the self demand, and can be the corresponding rotating speed obtained in the set rotating speed set based on the current temperature characteristic parameter and/or the humidity characteristic parameter.
In this embodiment, a plurality of value intervals may be divided in advance based on the relationship characteristic parameter, each value interval corresponds to a determining mode of a fan rotation speed, and the rotation speed of the current fan is determined according to the determining mode corresponding to the value interval where the current relationship characteristic parameter is located. Specifically, when the relation characteristic parameter is located in a first numerical interval, determining that the target rotating speed is the set rotating speed; when the relation characteristic parameters are located in a second numerical interval, determining a rotation speed adjustment parameter according to the relation characteristic parameters, and determining the target rotation speed according to the rotation speed adjustment parameter and the set rotation speed; and the value in the first value interval is smaller than the value in the second value interval, and the rotation speed adjusting parameter is in an increasing trend along with the increase of the relation characteristic parameter.
For example, the relationship characteristic parameter is a ratio between the ambient temperature value and the set comfort temperature, the first value interval is specifically [1.0,1.05], the second value interval is specifically [1.055,1.25], and the second value interval may be further divided into two subintervals: [1.055,1.15] and [1.155,1.25], on the basis of which a set rotational speed is defined as N, and when the ratio k between the ambient temperature value and the set comfort temperature is [1.0,1.05], the target rotational speed of the blower is N; when the ratio k between the ambient temperature value and the set comfort temperature is [1.055,1.15], the target rotating speed of the fan is k x N; when the ratio k between the ambient temperature value and the set comfort temperature is [1.155,1.25], the target rotation speed of the fan is 2k x n.
The determined target rotation speed is not greater than the maximum set rotation speed allowed to run by the fan. In this example, the maximum set rotational speed is 1400rpm.
In this embodiment, based on the above manner, on the basis that the realization of the air outlet regulation and control component in the above embodiment has no wind sense, condensation prevention and no influence on the indoor temperature reduction effect, the running rotation speed of the fan is regulated and controlled based on the indoor environment temperature and the set comfort temperature, so as to ensure that the air outlet of the air conditioner can further meet the temperature reduction requirement of the indoor environment, and ensure the wind sense and the temperature comfort of the indoor environment.
