When a wind sweeping action command sent by a user is received, the wind sweeping action command is an adjusting command which is sent by the user and can adjust at least one of the current wind guiding angle of the first wind guiding plate unit 1 and the second wind guiding plate unit 7.
Specifically, without detecting the wind speed, the user sends a wind sweeping command according to actual needs, the air deflector unit operates according to a set wind sweeping angle, and the second air deflector unit at the air outlet is combined to form a dual air deflecting phenomenon of the first air deflector unit and the second air deflector unit, so that when air flows through the first air deflector unit, the direction of the air entering the heat exchanger (such as the heat exchanger 8 in fig. 3) is changed, the original air flow distribution state is interfered, an air flow increasing or weakening effect can be formed with the second air deflector unit, and the air flow air outlet direction, the air outlet amount and the air outlet range are further adjusted. And when the air conditioner is in operation, the motor control module automatically adjusts, detects and adjusts the angle of the air deflector according to the wind speed detection result unless a user remote control wind sweeping instruction is received.
For example: when a wind sweeping action instruction is received, the motor control module does not detect a wind speed value, and controls the stepping motor to drive the air deflector to return to a default state, the motors in all the regions operate integrally according to a set angle, the air deflector in each region is driven by the motors to sweep wind according to the set angle (if the set angle is 20-160 degrees), until a wind sweeping pause instruction is received, the motor control module controls the motors to stop operating, the air deflector is driven to stop sweeping, and the air conditioner keeps the air deflector to continue operating at the angle.
Therefore, by adding the first air deflector unit between the fan (such as the fan 4 in fig. 3) and the heat exchanger (such as the heat exchanger 8 in fig. 3) of the split floor type air conditioner (such as the square cabinet air conditioner), that is, the first air deflector unit (such as the first air deflector unit 1 in fig. 2) added between the heat exchanger and the rear side plate, a user can control the opening angle or the air deflection angle of the air deflector in the first air deflector unit according to actual requirements, and forms a double air deflection phenomenon with the second air deflector unit (such as the second air deflector unit 7 in fig. 3) at the air outlet, so that the path of air flow passing through the first air deflector unit and the second air deflector unit is changed, the air outlet direction, the air outlet amount and the air outlet range of the air outlet air flow can be adjusted, and the comfort degree of the user is improved.
In some embodiments, the first air deflection unit 1 comprises: more than two air deflectors. The more than two air deflectors correspondingly divide the surface of the heat exchanger 8 into more than two areas. Each of the two or more air deflectors can guide air to a corresponding area on the surface of the heat exchanger 8.
Specifically, the first air deflector unit can guide the high wind speed of the rear side plate (such as the rear side plate 9 in fig. 3) to the surface of the heat exchanger (such as the heat exchanger 8 in fig. 3), and relieve the wind speed deviation between the rear side plate (such as the rear side plate 9 in fig. 3) and the heat exchanger (such as the heat exchanger 8 in fig. 3) so as to enhance the heat exchange effect of the surface of the heat exchanger (such as the heat exchanger 8 in fig. 3).
The first air deflector unit (such as the first air deflector unit 1 in fig. 2) is arranged behind the air outlet section of the fan (such as the fan 4 in fig. 3) and in front of the air inlet section of the heat exchanger (such as the heat exchanger 8 in fig. 3), forms a certain angle delta with the rear side plate, and is fixed on the left side plate and the right side plate. The first air deflector unit is composed of N air deflectors, such as a first air deflector, a second air deflector, a third air deflector, a fourth air deflector, a fifth air deflector, and N air deflectors, and correspondingly divides the surface of a heat exchanger (such as the heat exchanger 8 in fig. 3) into N regions, such as a first region N1, a second region N2, a third region N3, a fourth region N4, a fifth region N5, a.

When the air conditioner runs, the wind speed is defaulted to be automatically detected according to a set control method. That is, after the motor module automatically detects the wind speed η of each region, the wind speed average β is obtained, when the wind speed η of each region on the surface of the heat exchanger (e.g. the heat exchanger 8 in fig. 3) is greater than (or less than or equal to) the wind speed average β, the motor control module individually controls the rotation of each region motor according to the different wind speeds of each region, so as to control the angle of each region air deflector, guide the air flow distribution, and synchronously guide the high wind speed of the rear side plate to the surface of the heat exchanger (e.g. the heat exchanger 8 in fig. 3), so that the surface wind speed of the heat exchanger (e.g. the heat. The purposes of adjusting the surface wind speed uniformity of a heat exchanger (such as the heat exchanger 8 in the figure 3) and increasing the wind speed are achieved synchronously, and the heat exchange effect is enhanced.

Specifically, the wind speed value eta detected in a certain regioniIf the wind speed is larger than the average wind speed beta, the opening angle of the air deflector in the area is adjusted to reduce the wind speed, so that the airflow flows to the area beside the area, and the effect of increasing the wind speed of the nearby area is achieved. For example: the wind speed value eta detected when the second region isiIf the wind speed is larger than the average wind speed beta, the opening angle of the second air deflector is adjusted to reduce the wind speed, so that the air flow flows to the nearby area, and the effect of increasing the wind speed of the nearby area is achieved. The side area is a side area of the second area, such as the first area, the third area, the fourth area, the fifth area, and so on.

The control unit is specifically further configured to readjust the current wind guiding angle of the first wind deflector unit 1 according to the re-determined relationship between the wind speed of each of the two or more regions and the average wind speed value.
Specifically, after the wind guiding angle of the first wind deflector unit is adjusted each time, the wind speed value η of each region detected in real time is determined againiThe wind speed average β is recalculated.

Through a large number of tests, the technical scheme of the invention is adopted, the first air deflector unit is arranged between the fan and the heat exchanger of the split floor type air conditioner, the air deflection angle of the first air deflector unit is adjusted according to the detected air velocity to guide the air flow distribution, so that the air velocity distribution on the surface of the heat exchanger is uniform, and the heat exchange efficiency of the split floor type air conditioner is improved by improving the uniformity of the air velocity distribution on the surface of the heat exchanger of the split floor type air conditioner.
According to an embodiment of the present invention, there is also provided an air conditioner corresponding to a control device of the air conditioner. The air conditioner may include: the control device of the air conditioner described above.
In the related scheme, the indoor unit of the split floor type air conditioner is provided with a rear side plate (such as a rear side plate 9 in fig. 3), and the lower part of the indoor unit is provided with a fan (such as a fan 4 in fig. 3) and an indoor side air inlet (such as an air inlet 5 in fig. 3); the upper part is provided with an indoor heat exchanger (such as a heat exchanger 8 in figure 3) and an indoor air outlet. A heat exchanger (e.g., heat exchanger 8 in fig. 3) is typically placed on the rear side plate (e.g., rear side plate 9 in fig. 3) at an angle θ in the vertical direction, with the heat exchanger (e.g., heat exchanger 8 in fig. 3) at the rear side plate (e.g., rear side plate 9 in fig. 3). When the air conditioner works, indoor air is sucked and blown out through an air inlet (such as an air inlet 5 in a figure 3) and a fan (such as a fan 4 in a figure 3), and airflow flows through a heat exchanger (such as a heat exchanger 8 in a figure 3) and then flows out of an air outlet to the indoor space, so that the indoor air treatment process is completed.
Because the heat exchanger (such as the heat exchanger 8 in fig. 3) and the rear side plate (such as the rear side plate 9 in fig. 3) form a certain angle θ, the air of the air inlet (such as the air inlet 5 in fig. 3) is accelerated by the fan, when the air flows through the heat exchanger (such as the heat exchanger 8 in fig. 3) along the air duct, the closer to the rear side plate, the higher the air speed is, and the lower the air speed is on the surface of the heat exchanger (such as the heat exchanger 8 in fig. 3), i.e. the high air speed close to the rear side plate (such as the rear side plate 9 in fig. 3) is not effectively utilized, and the uneven distribution of the air speed on the surface of the heat exchanger (such as the heat exchanger 8 in fig. 3) causes the lower heat transfer coefficient on the surface of the heat exchanger (such as the heat; in addition, the uneven distribution of the wind speed on the surface of the heat exchanger (such as the heat exchanger 8 in fig. 3) synchronously affects the distribution of the airflow at the air outlet, thereby affecting the body feeling comfort of the human body at different temperatures and different positions.
In some schemes, an air distribution structure is arranged between an indoor unit fan and a heat exchanger, after the fan introduces air flow, the air flow flows through the air distribution structure, the air distribution structure disperses the air flow according to the position of the air distribution structure, the air flow is dispersed, the air speed gradient of a high-speed area and a low-speed area is relieved to a certain extent, the air speed difference is reduced, the flexibility of adjusting the air speed of the surface of the heat exchanger is weak, and the high air speed of a rear side plate cannot be effectively introduced to the surface of the heat exchanger, so that the air distribution structure cannot be used fully.
In some schemes, an air deflector is arranged between a fan and a heat exchanger, an air guide surface of the air deflector is arranged in an inclined windward mode relative to the air conveying direction of an outlet of the fan to the heat exchanger, air can be guided to the heat exchanger through the air guide function of the air deflector, heat exchange can be enhanced to a certain extent, however, the air deflector is fixed on a rear side plate at a specific angle and cannot be automatically adjusted according to the change of an actual wind field, and the effect of uniformly adjusting the wind speed of the upper portion and the lower portion of the surface of the heat exchanger is not strong.
In some schemes, a fixed air deflector is additionally arranged at the rear side plate similarly, the air deflector extends to the bottom of the heat exchanger, and the high air speed of the rear side plate is enhanced to guide and guide the flow.
Fig. 2 is a side view of the first air guiding plate unit in the indoor unit position. As shown in fig. 2, in the split floor type air conditioner (e.g., a square cabinet), the first air deflector unit 1 is disposed between a fan (e.g., a fan 4 in fig. 3) and a heat exchanger (e.g., a heat exchanger 8 in fig. 3).
In the example shown in fig. 2, θ is an included angle between the heat exchanger and the rear side plate, and the square cabinet machines in the related schemes should have angles; delta is the included angle between the first air guide unit and the rear side plate, and because the heat exchanger and the rear side plate are obliquely arranged, the first air guide unit is also provided with an oblique angle (delta is more than 0 and less than theta), so that the air flow is better guided to the surface of the heat exchanger.
Fig. 3 is a schematic view illustrating a flow direction of air when the first air deflector unit and the second air deflector unit are operated. As shown in fig. 3, in the split floor type air conditioner (such as a square cabinet air conditioner), an air inlet 5 is provided below a heat exchanger 8. A volute 2, a centrifugal fan blade 3 and a fan 4 are also arranged below the heat exchanger 8 in a matching manner. A first air deflector unit 1 is arranged between the fan 4 and the heat exchanger 8, and a second air deflector unit 7 is arranged at the air outlet. Between the heat exchanger 8 and the second air deflection unit 7, a baffle 6 is also provided.

The first air deflector unit is composed of N air deflectors, such as a first air deflector, a second air deflector, a third air deflector, a fourth air deflector, a fifth air deflector, and N air deflectors, and correspondingly divides the surface of a heat exchanger (such as the heat exchanger 8 in fig. 3) into N regions, such as a first region N1, a second region N2, a third region N3, a fourth region N4, a fifth region N5, a.
Wherein, each area is provided with a wind speed detector, and the wind speed detector is arranged at the middle position of each area (N1, N2 … … Nn) on the lower surface of the heat exchanger. Each air deflector is connected to a motor control module through a stepping motor, and the motor is controlled to rotate through the motor control module to control the opening angle of the air deflector.
On one hand, when the air conditioner runs, the wind speed is defaulted to be automatically detected according to a set control method; after the motor module automatically detects the wind speeds eta of all the regions, the wind speed average value beta is obtained, when the wind speeds eta of all the regions on the surface of the heat exchanger (such as the heat exchanger 8 in the figure 3) are larger than (or smaller than or equal to) the wind speed average value beta, the motor control module independently controls the motors of all the regions to rotate according to the different wind speeds of all the regions, so that the angles of the air deflectors of all the regions are controlled, the air flow distribution is guided, the high wind speed of the rear side plate is synchronously guided to the surface of the heat exchanger (such as the heat exchanger 8 in the figure 3), and the surface wind speed of the heat exchanger (such as the; the purposes of adjusting the surface wind speed uniformity of a heat exchanger (such as the heat exchanger 8 in the figure 3) and increasing the wind speed are achieved synchronously, and the heat exchange effect is enhanced.

In step S110, when the air conditioner is started and operated, the current wind guiding angle of the first wind guiding plate unit 1 is controlled to be a set angle (e.g., a wind guiding angle when the wind guiding plate is in a horizontal state). Specifically, the air conditioner is electrified to normally operate, and meanwhile, the motor control module is electrified to control the motor to drive the air deflector to be in a horizontal state.
In step S120, during the operation of the air conditioner, the wind speed of the lower surface of the heat exchanger 8 is detected.
In step S130, when a wind sweeping motion instruction sent by a user is not received, the current wind guiding angle of the first wind deflector unit 1 is adjusted according to the wind speed to guide the airflow distribution on the surface of the heat exchanger 8, so that the wind speed on the surface of the heat exchanger 8 tends to be uniform.
Specifically, the comfort level is adjusted in a synchronous and auxiliary manner with the main purposes of controlling the surface wind speed distribution uniformity of a heat exchanger (such as the heat exchanger 8 in fig. 3) and improving the heat exchange efficiency. Therefore, the opening angle or the air guide angle of the air guide plates in the first air guide plate unit can be automatically adjusted according to the air speed detection result through the first air guide plate unit to guide air flow distribution, the problem that the surface air speed distribution of a heat exchanger (such as the heat exchanger 8 in the figure 3) is not uniform is solved, and the air speed and the air volume on the surface of the heat exchanger (such as the heat exchanger 8 in the figure 3) are reasonably distributed.
Therefore, the first air deflector unit 1 is additionally arranged between the fan 4 and the heat exchanger 8 of the split floor type air conditioner (such as a square cabinet air conditioner), namely the first air deflector unit 1 is additionally arranged between the heat exchanger and the rear side plate, and the opening angle or the air guide angle of the air deflector in the first air deflector unit 1 is automatically adjusted according to the detected air speed, so that the air flow distribution is guided, the problem of uneven distribution of the air speed on the surface of the heat exchanger is solved, the heat exchange efficiency of the air conditioning system is improved, and the air conditioning performance is improved.
In some embodiments, the air conditioner further comprises: a second air deflection unit 7. And the second air deflector unit 7 is arranged at the air outlet of the air conditioner.

And when the air conditioner is in operation, the motor control module automatically adjusts, detects and adjusts the angle of the air deflector according to the wind speed detection result unless a user remote control wind sweeping instruction is received.
For example: when a wind sweeping action instruction is received, the motor control module does not detect a wind speed value, and controls the stepping motor to drive the air deflector to return to a default state, the motors in all the regions operate integrally according to a set angle, the air deflector in each region is driven by the motors to sweep wind according to the set angle (if the set angle is 20-160 degrees), until a wind sweeping pause instruction is received, the motor control module controls the motors to stop operating, the air deflector is driven to stop sweeping, and the air conditioner keeps the air deflector to continue operating at the angle.
