Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the disclosed embodiments are merely exemplary of the invention, and are not intended to be exhaustive or exhaustive. 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.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Fig. 2a, 2b, 2c and 2d show the distribution of air flow velocity when the air conditioner is installed in a room and operated in a normal operation mode. Fig. 2a and 2b are different views of airflow velocity distribution when the airflow of the single-opening air conditioner moves for a distance of 4 m. Fig. 2c and 2d are different views of airflow velocity distribution when the single-opening air conditioner airflow moves for a distance of 10 m.

As shown in fig. 2a and 2b, when the single-opening air conditioner air flow moves for a distance of 4m, when cold air at the air conditioner air outlet blows downwards, the air conditioner air outlet is close to the wall and is influenced by the Coanda Effect (Coanda Effect), the air flow speed at the side close to the wall is slow, the air flow speed at the side far away from the wall is fast, and obvious air flow adherence occurs, and at the moment, the user bed area is not influenced by the high-speed air flow at the outlet. As shown in fig. 2c and 2d, when the single-opening air conditioner airflow movement distance is lengthened to 10m, after cold air is blown out of the air conditioner air outlet and falls to the ground, the cold air rolls to the opposite wall of the air conditioner installation wall by adhering to the floor, then moves upwards, is influenced by the wardrobe and slightly accelerates, but after moving upwards to the ceiling, the airflow speed is greatly reduced, and the problem that the far-end air speed at the wall side of the air conditioner installation wall is too low occurs, so that the temperature of the area is reduced slowly, and the comfort is poor.

Typically, users consider using other appliances in conjunction with air conditioning, such as, for example, a conventional floor-mounted rotary vane fan, air circulation fan, tower fan, bladeless fan, etc. However, the control mode of the combined use of the household appliances between the household air conditioner and the fan is still in simple starting control and geometric association position selection, and the effect of adjusting the overall temperature in a room cannot be achieved fast in practice.

The invention provides a combined control method of an air conditioner and a fan.

Fig. 1 is a schematic method diagram of an embodiment of a method for controlling a combination of an air conditioner and a fan according to the present invention.

As shown in fig. 1, according to an embodiment of the present invention, the control method includes at least step S110 and step S120.

And step S110, determining the air flow adherence effect grade of the air outlet of the air conditioner when the air conditioner is started for refrigeration.

The gas flow adherence effects include: and more than two preset airflow adherence effect grades. Specifically, the coanda effect of the airflow of the air outlet of the air conditioner is divided into more than two levels. In a specific embodiment, the level of the air flow adherence effect of the outlet air of the air conditioner is determined according to the installation position information of the air conditioner. More specifically, the air flow adherence effect grade of the air conditioner outlet air is determined through the installation distance between the side plate of the air conditioner indoor unit and a wall parallel to the side plate.

For example, the installation distance between the side plate of the indoor unit of the air conditioner and the wall parallel to the side plate is obtained through methods such as mobile phone APP input, voice function dialogue input, installation position building house type big data, detection of an air conditioning radar system and the like, three-dimensional modeling is performed according to the installation distance between the side plate of the indoor unit of the air conditioner and the wall parallel to the side plate of the indoor unit of the air conditioner, CFD (Computational Fluid Dynamics) simulation analysis is performed, and a simulation analysis result is obtained. Optionally, the simulation analysis may be performed in the cloud. And matching the obtained simulation analysis result in a pre-established airflow adherence effect database to determine the airflow adherence effect grade of the air outlet of the air conditioner. Alternatively, the airflow adherence effect database can be established in advance in the cloud.

Fig. 3 is a flow chart illustrating an embodiment of determining a level of airflow adherence effect of outlet air of an air conditioner. As shown in fig. 3, in one embodiment, the air flow adherence effect of the outlet air of the air conditioner is divided into a high level, a medium level and a low level, and the corresponding adherence effect degrees are respectively severe, general and none.

And step S120, controlling the air conditioner and the fan according to a first preset control strategy according to the determined air flow adherence effect grade and the acquired temperature difference value between the current set temperature and the outdoor temperature of the air conditioner.

Specifically, whether the fan is started or not, whether the fan moves or not, the air outlet direction of the fan, the height of the fan and/or the angle of a wind sweeping blade of the air conditioner are/is controlled according to the determined air flow adherence effect grade and the current temperature difference value between the set temperature and the outdoor temperature of the air conditioner.

In one embodiment, the air flow adherence effect of the air conditioner outlet air is divided into high level, medium level and low level. The preliminary control strategies for different levels are as follows: high-level: the problem of adherence of air conditioner outlet airflow is serious, and the air conditioner indoor unit wind sweeping blades are matched with a fan to realize rapid temperature regulation in a room; and (3) intermediate stage: the problem of adherence of air conditioner outlet airflow is common, and according to the temperature difference between the set temperature and the outdoor temperature of an air conditioner, the rapid temperature regulation in a room is realized by adjusting the angle of a wind sweeping blade of an indoor unit of the air conditioner or matching the wind sweeping blade of the indoor unit of the air conditioner with a fan; low-grade: the air outlet flow of the air conditioner has no adherence problem, and does not need additional control and regulation. In one embodiment, the preset two or more levels of airflow adherence effect comprise: high, medium and low. The first preset control strategy may specifically include:

(1) the air current adherence effect grade of air conditioner air-out is under the advanced condition, and the air current adherence problem of air conditioner air-out is more serious when the temperature difference of setting for temperature and outdoor temperature of air conditioner is greater than the second and predetermines the temperature threshold value, controls the linkage of the fan blade cooperation fan of sweeping the wind of air conditioner realizes indoor temperature control, when the temperature difference less than or equal to second that sets for temperature and outdoor temperature predetermines the temperature threshold value, can not control the fan is opened, only controls the fan blade angle of sweeping the wind of air conditioner, wherein, control the linkage of the fan blade cooperation fan of sweeping the air conditioner specifically can include: when the temperature difference value between the set temperature of the air conditioner and the outdoor temperature is greater than or equal to a first preset temperature threshold value, controlling the angle of an included angle between the air outlet direction of the fan and the wall-adhering direction to be smaller than a first preset angle and greater than a second preset angle, and controlling the air sweeping blades of the air conditioner to reach the maximum angle so as to enable the air outlet direction of the air conditioner to be far away from the wall-adhering area; when the temperature difference value of the set temperature and the outdoor temperature of the air conditioner is smaller than a first preset temperature threshold value and larger than a second preset temperature threshold value, the angle of the included angle between the air outlet direction of the fan and the wall sticking direction is controlled to be smaller than or equal to a second preset angle, and the air sweeping blades of the air conditioner are controlled to reach the maximum angle, so that the air outlet direction of the air conditioner is far away from the wall sticking area.

And performing three-dimensional modeling according to the installation distance between the side plate of the indoor unit of the air conditioner and a wall parallel to the side plate, performing CFD (Computational Fluid Dynamics) simulation analysis to obtain a simulation analysis result of the air-conditioning outlet airflow, and determining the adherent region and the adherent direction of the air-conditioning outlet airflow according to the simulation analysis result. For example, three-dimensional modeling is performed at the cloud end, rapid CFD is performed, and relevant position information exists in the obtained simulation analysis result, so that the wall adhering region and the wall adhering direction of the air outlet flow of the air conditioner can be determined. Through controlling the angle of the air-out direction of fan and the contained angle of adherence direction can control air conditioner air-out direction, the angle of the air-out direction of fan and the contained angle of adherence direction is big more, and is big more to the change of the wind direction of air conditioner air-out, and it needs to be noted that the biggest angle is not necessarily the best air current circulation angle, needs to set for relevant angle. The air outlet angle at the air outlet of the air conditioner can be controlled by controlling the angle of the air sweeping blade of the air conditioner. The larger the angle of the wind sweeping blade is, the farther the air outlet direction is from the wall close to the air outlet, and the smaller the wall sticking effect is.

The specific control logic is as follows:

when the temperature difference value of the set temperature of the air conditioner and the outdoor temperature is larger than or equal to a first preset temperature threshold value, the fan is controlled to be opened, the fan is controlled to move and adjust, the height of the fan is enabled to be the fan which is located in the wall-adhering region, the angle of the air outlet direction of the fan and the included angle of the wall-adhering direction is smaller than a first preset angle and larger than a second preset angle, the wind sweeping blade of the air conditioner is controlled to reach the maximum angle, and the air outlet direction of the air conditioner is far away from the wall-adhering region. The first preset angle is larger than the second preset angle.

Work as when the temperature difference of the settlement temperature of air conditioner and outdoor temperature is less than first predetermined temperature threshold and is greater than the second and predetermines the temperature threshold, control the fan is opened, and through control the fan removes and adjusts the fan highly makes the fan is in the adherence region, controls the angle less than or equal to second of the air-out direction of fan and the contained angle of adherence direction predetermines the angle, controls the wind blade that sweeps of air conditioner reaches the maximum angle, so that the adherence region is kept away from to the air-out direction of air conditioner. The first preset temperature threshold is larger than the second preset temperature threshold.

And when the temperature difference value between the set temperature of the air conditioner and the outdoor temperature is less than or equal to a second preset temperature threshold value, the fan is not controlled to be started, and the wind sweeping blades of the air conditioner are controlled to reach the maximum angle, so that the air outlet direction of the air conditioner is far away from the wall adhering area.

Through control the air-out direction of fan can be controlled with the angle of the contained angle of adherence direction to the air-out direction of fan, the air-out direction of fan is the bigger with the angle of the contained angle of adherence direction, and is bigger to the change of the wind direction of air conditioner air-out. Under the serious condition of the air current adherence effect of air conditioner air-out, the greater the temperature difference between the set temperature of air conditioner and the outdoor temperature is, the greater the angle of the included angle between the air-out direction of the fan and the adherence direction is, the faster the improvement of the air current adherence is, and the quick temperature regulation can be realized by combining the angle control of the air conditioner air sweeping blade. When the temperature difference between the set temperature of the air conditioner and the outdoor temperature is small, the rapid temperature adjustment can be realized only by controlling the angle of the wind sweeping blade of the air conditioner.

(2) The air current adherence effect grade of air conditioner air-out is under the condition of middling level, and the air current adherence problem of air conditioner air-out is general when the temperature difference value more than or equal to first preset temperature threshold value of the temperature setting for temperature and outdoor temperature of air conditioner, wherein, first preset temperature threshold value is greater than the second and presets temperature threshold value, controls sweep the linkage of wind blade cooperation fan of air conditioner realizes indoor temperature control, when the temperature difference value less than or equal to first preset temperature threshold value of setting for temperature and outdoor temperature, can not control the fan is opened (do not ally oneself with the fan promptly), only controls the wind blade angle of sweeping of air conditioner, wherein, control sweep the linkage of wind blade cooperation fan of air conditioner, specifically can include: and controlling the angle of the included angle between the air outlet direction of the fan and the wall-adhering direction to be smaller than or equal to a second preset angle, and controlling the wind sweeping blade of the air conditioner to reach the maximum angle so as to enable the air outlet direction of the air conditioner to be far away from the wall-adhering area.

The specific control logic is as follows:

when the temperature difference between the set temperature of the air conditioner and the outdoor temperature is larger than or equal to a first preset temperature threshold value, the fan is controlled to be opened, the fan is controlled to move and adjust, the height of the fan is enabled to be in the wall-adhering region, the angle between the air outlet direction of the fan and the included angle between the wall-adhering direction is controlled to be smaller than or equal to a second preset angle, the air sweeping blades of the air conditioner are controlled to reach the maximum angle, and therefore the air outlet direction of the air conditioner is far away from the wall-adhering region.

When the temperature difference value between the set temperature of the air conditioner and the outdoor temperature is smaller than a first preset temperature threshold value, the fan is not controlled to be started, and the wind sweeping blades of the air conditioner are controlled to reach the maximum angle, so that the air outlet direction of the air conditioner is far away from the wall adhering area.

Through control the air-out direction of fan can be controlled with the angle of the contained angle of adherence direction to the air-out direction of fan, the air-out direction of fan is the bigger with the angle of the contained angle of adherence direction, and is bigger to the change of the wind direction of air conditioner air-out. Under the general condition of the air flow wall-attached effect of air outlet of the air conditioner, when the temperature difference between the set temperature of the air conditioner and the outdoor temperature is large, the air outlet direction of the fan and the wall-attached direction are controlled by the angle, and the air conditioner is combined with the angle control of the air sweeping blades to realize rapid temperature adjustment. When the temperature difference between the set temperature of the air conditioner and the outdoor temperature is not large, the rapid temperature adjustment can be realized only by controlling the angle of the wind sweeping blade of the air conditioner.

(3) Under the condition that the air flow adherence effect grade of air-conditioner air-out is low, the air flow of air-conditioner air-out basically has no adherence problem, the fan can not be controlled to be opened (namely, the fan is not used), when the temperature difference value of the set temperature and the outdoor temperature is more than or equal to a first preset temperature threshold value, the angle of the air-sweeping blade of the air-conditioner is controlled, when the temperature difference value of the set temperature and the outdoor temperature is less than or equal to the first preset temperature threshold value, normal starting setting is carried out, and the specific control logic is as follows:

when the temperature difference value between the set temperature of the air conditioner and the outdoor temperature is larger than or equal to a first preset temperature threshold value, the fan is not controlled to be started, and the wind sweeping blades of the air conditioner are controlled to reach the maximum angle, so that the air outlet direction of the air conditioner is far away from the wall adhering area.

And when the temperature difference value between the set temperature of the air conditioner and the outdoor temperature is smaller than a first preset temperature threshold value, the fan is not controlled to be started, and normal starting setting is carried out.

Through control the air-out direction of fan can be controlled with the angle of the contained angle of adherence direction to the air-out direction of fan, the air-out direction of fan is the bigger with the angle of the contained angle of adherence direction, and is bigger to the change of the wind direction of air conditioner air-out. Under the condition that the air flow of the air outlet of the air conditioner basically has no adherence problem, and when the temperature difference between the set temperature of the air conditioner and the outdoor temperature is large, the rapid temperature regulation is realized through the angle control of the air sweeping blades of the air conditioner. When the temperature difference between the set temperature of the air conditioner and the outdoor temperature is not large, the air conditioner can be set to normally operate according to the starting, and special control is not performed. The power-on setting refers to a set state when the air conditioner is powered on, such as a state set by a remote controller or an APP at that time.

The control strategy described above can be referred to the example of table 1. Table 1 shows an execution logic comparison table of a first control strategy according to an embodiment of the present invention, where the first preset temperature threshold is 10 ℃, the second preset temperature threshold is 3 ℃, the first preset angle is 120 °, and the second preset angle is 100 °.

TABLE 1

In the case that the adherence effect level is high, the air flow optimization effect achieved through the fan opening, the position movement and the height adjustment and the control of 3 parameters can be referred to fig. 4a, 4b, 4c and 4d, and fig. 4a and 4b respectively show different angle views of the air flow speed when the air flow moves for a distance of 4m when the air conditioner and the fan are combined. Fig. 4c and 4d show different angle views of the air flow velocity at a distance of 10m, respectively, when the air conditioner is used with a fan.

As shown in fig. 4a and 4b, when the air conditioner and the air circulation fan are used together, when the air circulation fan is located at the air outlet section of the air conditioner, the air outlet of the air conditioner is greatly affected, and the air outlet direction is basically changed. The air conditioner and the air circulation fan are mutually influenced, the air flow organization moves diagonally towards the air conditioner installation along with bed legs, the bed area is less in a high-speed air outlet area, but the wind speed reaches more than 4m/s, and the wind sensation is very strong. Further, when the movement distance of the airflow is elongated to 10m, as shown in fig. 4c and 4d, the movement mode and distribution of the airflow discharged from the air conditioner are changed greatly, and the phenomenon of wall-adhering circulation occurs.

Compared with the condition of single-opening air conditioners, except that the corner areas are located in high-wind-speed areas, other areas of the bed are all located in low-wind or windless areas, cold wind does not directly blow people, and comfort experience is good.

The invention also provides a combined control device of the air conditioner and the fan.

Fig. 7 is a block diagram of an embodiment of a combination control device for an air conditioner and a fan according to the present invention. As shown in fig. 7, the joint control apparatus 100 includes a determination unit 110 and a control unit 120.

The determining unit 110 is configured to determine an airflow adherence effect level of outlet air of the air conditioner when the air conditioner is started for cooling.

The gas flow adherence effect comprises: and more than two preset airflow adherence effect grades. Specifically, the coanda effect of the airflow of the air outlet of the air conditioner is divided into more than two levels. In a specific embodiment, the air flow adherence effect grade of the air outlet of the air conditioner is determined according to the installation position information of the air conditioner. More specifically, the air flow adherence effect grade of the air conditioner outlet air is determined by the installation distance between the side plate of the air conditioner indoor unit and the wall parallel to the side plate.

And a control unit 120, configured to control the air conditioner and the fan according to a first preset control strategy according to the airflow adherence effect level determined by the determination unit 110 and a temperature difference between a current set temperature of the air conditioner and an outdoor temperature.

Specifically, the control unit 120 controls whether the fan is turned on, whether the fan moves, the air outlet direction of the fan, the height of the fan, and/or the angle of the air-sweeping blade of the air conditioner according to the determined air flow adherence effect level and the temperature difference between the current set temperature of the air conditioner and the outdoor temperature.

In one embodiment, the air flow adherence effect of the air conditioner outlet air is divided into high level, medium level and low level. The preliminary control strategies for different levels are as follows: high-level: the problem of adherence of air conditioner outlet airflow is serious, and the air conditioner indoor unit wind sweeping blades are matched with a fan to realize rapid temperature regulation in a room; and (3) intermediate stage: the problem of adherence of air conditioner outlet airflow is common, and according to the temperature difference between the set temperature and the outdoor temperature of an air conditioner, the rapid temperature regulation in a room is realized by adjusting the angle of a wind sweeping blade of an indoor unit of the air conditioner or matching the wind sweeping blade of the indoor unit of the air conditioner with a fan; low-grade: the air outlet flow of the air conditioner has no adherence problem, and does not need additional control and regulation.

In one embodiment, the preset two or more levels of airflow adherence effect comprise: high, medium and low. The first preset control strategy may specifically include:

(1) the air current adherence effect grade of air conditioner air-out is the advanced condition under, and the air current adherence problem of air conditioner air-out is more serious when the temperature difference of the temperature setting for of air conditioner and outdoor temperature is greater than the second and predetermines the temperature threshold value, controls the linkage of the fan cooperation fan of sweeping the wind blade of air conditioner realizes indoor temperature control, and when the temperature difference of temperature setting for and outdoor temperature is less than or equal to the second and predetermines the temperature threshold value, can not control the fan is opened, only controls the angle of the blade of sweeping the wind blade of air conditioner, wherein, control the linkage of the blade cooperation fan of sweeping the wind blade of air conditioner specifically can include: when the temperature difference value between the set temperature of the air conditioner and the outdoor temperature is greater than or equal to a first preset temperature threshold value, controlling the angle of the included angle between the air outlet direction of the fan and the wall-adhering direction to be smaller than a first preset angle and greater than a second preset angle, and controlling the air sweeping blades of the air conditioner to reach the maximum angle so that the air outlet direction of the air conditioner is far away from the wall-adhering area; when the temperature difference value between the set temperature and the outdoor temperature of the air conditioner is smaller than a first preset temperature threshold value and larger than a second preset temperature threshold value, the angle of the included angle between the air outlet direction of the fan and the wall sticking direction is controlled to be smaller than or equal to a second preset angle, and the air sweeping blades of the air conditioner are controlled to reach the maximum angle, so that the air outlet direction of the air conditioner is far away from the wall sticking area.

The specific control logic is as follows:

when the temperature difference value of the set temperature of the air conditioner and the outdoor temperature is larger than or equal to a first preset temperature threshold value, the fan is controlled to be opened, the fan is controlled to move and adjust, the height of the fan is enabled to be the fan which is located in the wall-adhering region, the angle of the air outlet direction of the fan and the included angle of the wall-adhering direction is smaller than a first preset angle and larger than a second preset angle, the wind sweeping blade of the air conditioner is controlled to reach the maximum angle, and the air outlet direction of the air conditioner is far away from the wall-adhering region. The first preset angle is larger than the second preset angle. Work as when the temperature difference of the settlement temperature of air conditioner and outdoor temperature is less than first predetermined temperature threshold value and is greater than the second and predetermines the temperature threshold value, control the fan is opened, and through control the fan removes and adjusts the fan highly makes the fan is in the adherence region, controls the angle less than or equal to second of the air-out direction of fan and the contained angle of adherence direction predetermines angle control the wind blade of sweeping of air conditioner reaches the maximum angle, so that the adherence region is kept away from to the air-out direction of air conditioner. The first preset temperature threshold is larger than the second preset temperature threshold. And when the temperature difference value between the set temperature of the air conditioner and the outdoor temperature is less than or equal to a second preset temperature threshold value, the fan is not controlled to be started, and the wind sweeping blades of the air conditioner are controlled to reach the maximum angle, so that the air outlet direction of the air conditioner is far away from the wall adhering area.

Through controlling the angle of the air-out direction of fan and the contained angle of adherence direction can control air conditioner air-out direction, the angle of the air-out direction of fan and the contained angle of adherence direction is big more, and is big more to the change of the wind direction of air conditioner air-out. Under the serious condition of the air current adherence effect of air conditioner air-out, the greater the temperature difference between the set temperature of air conditioner and the outdoor temperature is, the greater the angle of the included angle between the air-out direction of the fan and the adherence direction is, the faster the improvement of the air current adherence is, and the quick temperature regulation can be realized by combining the angle control of the air conditioner air sweeping blade. When the temperature difference between the set temperature of the air conditioner and the outdoor temperature is small, the rapid temperature adjustment can be realized only by controlling the angle of the wind sweeping blade of the air conditioner.

(2) Under the condition that the air current adherence effect grade of air conditioner air-out is the middling, the air current adherence problem of air conditioner air-out is general when the temperature difference value more than or equal to first default temperature threshold value of setting for temperature and outdoor temperature of air conditioner, wherein, first default temperature threshold value is greater than the second and predetermines temperature threshold value, controls the linkage of the fan blade that sweeps the wind of air conditioner cooperates the fan, realizes indoor temperature control, when the temperature difference value less than or equal to first default temperature threshold value of setting for temperature and outdoor temperature, can not control the fan is opened (not allies oneself with and uses the fan promptly), only controls the fan blade angle that sweeps the wind of air conditioner, wherein, control the linkage of the fan blade that sweeps the wind of air conditioner cooperates the fan specifically can include: and controlling the angle of the included angle between the air outlet direction of the fan and the wall-adhering direction to be smaller than or equal to a second preset angle, and controlling the wind sweeping blade of the air conditioner to reach the maximum angle so as to enable the air outlet direction of the air conditioner to be far away from the wall-adhering area. The specific control logic is as follows:

when the temperature difference between the set temperature of the air conditioner and the outdoor temperature is larger than or equal to a first preset temperature threshold value, the fan is controlled to be opened, the fan is controlled to move and adjust, the height of the fan is enabled to be in the wall-adhering region, the angle between the air outlet direction of the fan and the included angle between the wall-adhering direction is controlled to be smaller than or equal to a second preset angle, the air sweeping blades of the air conditioner are controlled to reach the maximum angle, and therefore the air outlet direction of the air conditioner is far away from the wall-adhering region. When the temperature difference value between the set temperature of the air conditioner and the outdoor temperature is smaller than a first preset temperature threshold value, the fan is not controlled to be started, and the wind sweeping blades of the air conditioner are controlled to reach the maximum angle, so that the air outlet direction of the air conditioner is far away from the wall adhering area.

(3) Under the condition that the air flow adherence effect grade of air conditioner air-out is low, the air flow of air conditioner air-out basically has no adherence problem, can not control the fan is opened (namely the fan is not used), when setting for the temperature difference value of temperature and outdoor temperature is more than or equal to a first preset temperature threshold value, the angle of the air-sweeping blade of the air conditioner is controlled, when setting for the temperature difference value of temperature and outdoor temperature is less than or equal to the first preset temperature threshold value, the normal start-up setting is carried out, and the concrete control logic is as follows:

when the temperature difference value between the set temperature of the air conditioner and the outdoor temperature is larger than or equal to a first preset temperature threshold value, the fan is not controlled to be started, and the wind sweeping blades of the air conditioner are controlled to reach the maximum angle, so that the air outlet direction of the air conditioner is far away from the wall-adhering area. And when the temperature difference value between the set temperature of the air conditioner and the outdoor temperature is smaller than a first preset temperature threshold value, the fan is not controlled to be started, and normal starting setting is carried out.

Through controlling the angle of the air-out direction of fan and the contained angle of adherence direction can control air conditioner air-out direction, the angle of the air-out direction of fan and the contained angle of adherence direction is big more, and is big more to the change of the wind direction of air conditioner air-out. Under the condition that the air flow of the air outlet of the air conditioner basically has no adherence problem, and when the temperature difference between the set temperature of the air conditioner and the outdoor temperature is large, the rapid temperature regulation is realized through the angle control of the air sweeping blades of the air conditioner. When the temperature difference between the set temperature of the air conditioner and the outdoor temperature is not large, the air conditioner can be set to normally operate according to the starting, and special control is not performed. The power-on setting refers to a set state when the air conditioner is powered on, such as a state set by a remote controller or an APP at that time.
