However, such control can perform a control only according to the temperature of the floor, but there is a problem in that an unnecessary air control can be accomplished for an area where a user does not mainly move or live or cannot live.

SUMMARY OF THE INVENTION

The present invention has been made in view of the above problems, and provides an air conditioner that maintains a comfortable indoor space in consideration of the living environment of occupants, and a control method thereof.
It is an object of the present invention to provide an air conditioner capable of quickly reaching a desired temperature of an indoor space in the living area of an occupant, and maintaining the comfort of the indoor space while minimizing the air flow in a direction of the occupant when it approaches the desired temperature, and a control method thereof.
It is an object of the present invention to provide an air conditioner capable of increasing the accuracy of classification between living area and non-living area of an indoor space, and a control method thereof.
The object of the present invention is solved by the features of the independent claims. Preferred embodiments are given in the dependent claims.
In accordance with an aspect of the present invention, the air conditioner includes: a plurality of outlets opened downward and a plurality of wind adjusters disposed in the plurality of outlets, and a controller is configured to divide the plurality of outlets into a first area outlet facing a living area and a second area outlet facing a non-living area based on accumulated data of the image information obtained from the camera, and adjusts each of the plurality of wind adjusters so that air discharged from the first area outlet and air discharged from the second area outlet are formed differently in the up-and-down side direction, so that the airflows discharged to the living area and the non-living area can be formed differently.
The air conditioner may further include a temperature sensor for detecting a temperature of the indoor space.
The controller may adjust the wind adjuster to change airflow in the up-and-down side direction of the first area outlet, when the temperature detected by the temperature sensor is within a set temperature range, so that airflow can be set differently depending on whether the indoor temperature is within or beyond the set temperature range.
When the temperature detected by the temperature sensor is beyond a set range, the controller may control the wind adjuster so that air discharged to the first area outlet is formed or blown lower in an up-and-down side direction than air discharged to the second outlet, so that direct airflow can be formed in the living area., to thereby reduce the temperature in that first area.
When the temperature detected by the temperature sensor is within a set range, the controller may adjust the wind adjuster so that air discharged through the first outlet is formed higher in an up-and-down side direction than air discharged through the second area outlet, so that indirect airflow can be formed in the living area.
The controller may adjust the wind adjuster so that air discharged through the first area outlet is discharged in a first direction toward a ground, when the temperature detected by the temperature sensor is beyond a set range, and may adjust the wind adjuster so that the air discharged to the first area outlet is discharged in a second direction toward an upper side than the first direction, when the temperature detected by the temperature sensor is within the set temperature range, so that the airflow range can be adjusted in the up-and-down side direction according to the temperature of the indoor air.

Referring to FIGS. 5A and 5B, when the wind adjuster 130 is disposed in the third position P3, the air discharged from the outlet 124 may flow in a third direction D3.
The third direction D3 may be formed to have a different range under the heating condition and the cooling condition. Referring to FIG. 5A, in the heating condition, the third direction D3 may mean that the angle, which is formed between a direction in which the main airflow of the air discharged from the outlet 124 flows and a ground, is formed in a range of 30 degrees to 60 degrees. Referring to FIG. 5B, in the cooling condition, the third direction D3 may mean that the angle, which is formed between a direction in which the main airflow of the air discharged from the outlet 124 flows and a ground, is formed in a range of 45 degrees to 60 degrees.
The angle ranges of the first direction D1, the second direction D2, and the third direction D3 are just an embodiment, and may be set differently depending on a space in which the air conditioner is disposed or a structure of the air conditioner.
In addition, in FIGS. 5A to 5B, there are three divided areas, but there can be 4 to 6 subdivided areas.

The air conditioner of the present invention includes a camera 510 which is disposed in one side of the panel 120, and obtains image information of an indoor space.
The air conditioner of the present invention may also include an output unit 530 that outputs the image information obtained from the camera 510
The air conditioner of the present invention preferably includes a temperature sensor 520 that detects the temperature of the indoor space. According to the invention, a controller 500 adjusts the wind adjuster 130 based on the image information obtained from the camera 510
Referring to FIG. 7A(a), the output unit 530 may be divided into a plurality of areas. The output unit 530 of FIG. 7A(a) may be divided into a plurality of areas (I, II, III, IV, V, VI) which are divided based on a direction in which the plurality of outlets 124a, 124b, 124c, and 124d disposed in the air conditioner of FIG. 7A(b) are directed.
Referring to FIG. 7A(a), the area displayed on the output unit 530 may be divided into a first area (I), a second area (II), a third area (III), and a fourth area (IV) based on the outlet 124a, 124b, 124c, and 124d shown in FIG. 7A(b). In addition, according to the screen display of the output unit 530, an additional area may be divided into a fifth area (V) and a sixth area (VI) in the outside of the second area (II) and the fourth area (IV).
Referring to FIG. 7B(a), the area displayed on the output unit 530 may be divided into a first area (I), a second area (II), a third area (III), and a fourth area (IV) based on the outlet 124a, 124b, 124c, and 124d shown in FIG. 7A(b). In addition, an additional area may be divided into a fifth area (V) and a sixth area (VI) in the outside of the second area (II) and the fourth area (IV), and an additional area may be divided into a seventh area (V) and an eighth area (VI) in the outside of the first area (I) and the third area (III).
The controller 500 may determine the living area of the occupant based on the image obtained by the camera 510. The controller 500 may capture an image photographed by the camera 510, and detect a human body based on the obtained image. In addition, by accumulating position information of the human body based on the accumulated image information, it is possible to determine an area in which the position information of the human body is accumulated as a living area.
The camera 510 may include an image sensor (not shown) that converts light into an electrical signal. The image sensor may include a plurality of photodiodes corresponding to a plurality of pixels constituting an image. The image sensor may be implemented of a charged coupled device (CCD) sensor or a complementary metal oxide semiconductor (CMOS) sensor, but the present invention is not limited thereto.
Meanwhile, the air conditioner may further include a lens through which light emitted from a subject passes, a digital signal processor which constructs and processes an image based on a signal output from the image sensor, and the like. Here, the digital signal processor may be configured as at least a portion of the controller 500, or may be configured as a separate processor operated independently of the controller 500. For example, when the digital signal processor is configured as a separate processor, the image processed by the digital signal processor may be stored in a storage unit 540 by the controller 500 intactly or after an additional processing.
The controller 500 may process the image obtained through the image sensor. For example, the controller 500 may remove noise from an image, or may perform signal processing such as gamma correction, color filter array interpolation, color matrix, color correction, and color enhancement for an image.
The controller 500 may detect an object included in the image using at least one method. For example, the controller 500 may extract a feature point included in the image through a method such as scale invariant feature transform (SIFT), and histogram of oriented gradient (HOG), and may detect an object included in the image based on the extracted feature point. In this case, the controller 500 may detect the object included in the image by determining a boundary of the object through an algorithm such as a support vector machine (SVM), and Adaboost.
The controller 500 may detect a motion of an object included in the plurality of images, based on a result of processing the plurality of images. For example, the controller 500 may calculate a motion vector for a plurality of pixels constituting the object detected from the image by using a dense optical flow method, and may compute the motion of the object based on the calculated motion vector. In the present embodiment, it is described that a dense optical flow method is used, but the present invention is not limited thereto, and a sparse optical flow method of calculating a motion vector for some characteristic pixels may be used.
The controller 500 may determine the amount of activity of the object detected from the image. For example, the controller 500 may determine the amount of activity of the object included in the image, according to a value obtained by dividing the sum of the magnitudes of motion vectors for pixels constituting the object by the number of pixels constituting the object.
The air conditioner of the present invention may include a storage unit 540 for storing an image obtained from the camera 510 and a timer 550 for measuring an image acquisition time of the camera 510. The storage unit 540 may sequentially store images obtained from the camera 510.
After a set time measured by the timer 550, the controller 500 may classify the user's living area from the accumulated image information obtained from the camera, thereby increasing the accuracy of the classification between the living area and the non-living area.
Referring to FIGS. 8A to 8C, based on the image information obtained from the camera 510, the first area (I), the fourth area (IV), and the sixth area (VI) are determined as living area, and the second area (II), the third area (III), and the fifth area (V) may be determined as non-living area. At this time, the outlet 124a and 124d disposed to face the first area (I), the fourth area (IV), and the sixth area (VI) may be set as a first area outlet 124-1, and the outlet 124b and 124c disposed to face the second area (II), the third area (III), and the fifth area (V) may be set as a second area outlet 124 - 2.
Specifically, as shown in FIG. 8A, the screen displayed on the output unit 530 is divided into a plurality of areas based on the area where the outlet is disposed. The image shown in FIG. 8A is an image photographed from a ceiling through the camera 510 disposed in one side of the panel 120.
As shown in FIG. 8B, an area in which a human body is detected is extracted based on the accumulated image information. Based on the data extracted in FIG. 8B, the area divided in the output unit 530 is divided into a living area and a non-living area as shown in FIG. 8C.
The controller 500 may receive human body detection data including a result of recognizing an occupant's position from the image information obtained from the camera 510, and may accumulate the received human body detection data. The controller 500 may generate a histogram, if a certain number or more of data is accumulated while accumulating and counting human body detection data.
The controller 500 may use the generated histogram as input data to classify a living area and a non-living area based on machine learning. The machine learning may use a technique such as a support vector machine (SVM) or Adaboost, and more preferably, use a deep learning technique.
The controller 500 may include an artificial neural network pre-learned by machine learning, generate a histogram for each of a plurality of areas, and use the generated histogram as input data of the artificial neural network to classify the living area and the non-living area.
In addition, while repeatedly performing the above process, the controller 500 may collect a plurality of classification result, and finally classify the plurality of areas of the indoor space into living area and non-living area based on the collected result. That is, by deriving the final result when the living area classification result is accumulated over a certain number, the reliability of the living area recognition result can be secured, and temporary errors in the non-living area caused by the human body detection error can be removed.
The controller 500 may adjust a first area wind adjuster 130 disposed in the first area outlet 124-1 disposed in the living area. The controller 500 may adjust a second area wind adjuster 130 disposed in the second area outlet 124-2 disposed in the non-living area.
The controller 500 may adjust the second wind adjuster 130 to uniformly form a discharge direction of the second area outlet 124-2 disposed in the non-living area. The controller 500 may adjust the first area wind adjuster 130 so that the discharge direction of the first area outlet 124-1 disposed in the living area is formed to be higher or lower than the discharge direction of the second area outlet 124-2.
The controller 500 may adjust the wind adjuster 130 based on the temperature of the indoor space detected by the temperature sensor 520 and a desired temperature set by a user.
The controller 500 may adjust the wind adjuster 130 depending on whether the temperature of the indoor space detected by the temperature sensor 520 is within or outside a set temperature range.
The set temperature range may be set to a value which is obtained by considering a correction temperature for the desired temperature set by a user. The desired temperature may be set by a user. The correction temperature may be set according to a use environment, and the like.
That is, the set temperature range may be set to a desired temperature ± a correction temperature. Referring to FIG. 9, when the correction temperature is set to 2 degrees, the controller 500 may determine as the set temperature range from an area that is 2 degrees higher than the desired temperature.
The controller 500 may adjust the second area wind adjuster 130 so that the air discharged from the second area outlet 124-2 flows in the third direction D3. Referring to FIGS. 10A to 10B, the air discharged from the second area outlet 124-2 may be formed uniformly regardless of the temperature of the indoor space. However, the air discharged from the second area outlet 124-2 may have different up-and-down side airflows depending on the cooling condition or the heating condition.
The controller 500 may adjust the first area wind adjuster 130 so that the air discharged from the first area outlet 124-1 flows in the first direction D1 or the third direction D3. Referring to FIG. 10A, when the temperature detected by the temperature sensor 520 is beyond the set temperature range, the first area wind adjuster 130 may be controlled so that the air discharged from the first area outlet 124-1 flows in the second direction D2 that is lower than the third direction D3. Referring to FIG. 10B, when the temperature detected by the temperature sensor 520 is within the set temperature range, the first area wind adjuster 130 may be controlled so that the air discharged from the first area outlet 124-1 flows in the first direction D1 that is higher than the third direction D3.
Hereinafter, a method of controlling the air conditioner will be described with reference to FIGS. 11 to 13.
The air conditioner is operated, and the camera 510 goes through a step S100 of obtaining image information. The camera 510 may be disposed in one side of the panel 120 to photograph the lower space from a ceiling of an indoor space.
Thereafter, the controller 500 undergoes a step S200 of determining a living area with respect to a space photographed by the camera 510, based on the accumulated data of image information obtained by the camera 510. In the step S200 of determining the living area, a portion having a high accumulated detection of the human body may be classified as a living area, and the remaining area may be classified as a non-living area. In the step S200 of determining the living area, the plurality of outlets 124a, 124b, 124c and 124d may be classified into a first area outlet 124-1 facing the living area and a second area outlet 124-2 facing the non-living area.
Referring to FIG. 12, the step S200 of determining as the living area and the non-living area may include a step S210 of detecting a human body with respect to the image obtained from the camera 510, and a step S220 of accumulating position information of the human body.
The controller 500 may capture the image photographed by the camera 510, and detect a human body based on the obtained image. In addition, an area in which the position information of the human body is accumulated may be determined as a living area, by accumulating the position information of the human body based on the accumulated image information.
The controller 500 may determine an area in which the human body information is accumulated as a living area, and may determine the remaining area as a non-living area, based on the plurality of areas partitioned in the output unit 530.
The step S200 of determining as the living area and the non-living area may include a step S230 of determining whether a set time for the camera 510 to obtain image information has elapsed. When the set time for the camera 510 to acquire image information is elapsed, the controller 500 may divide the indoor space into the living area and the non-living area through the accumulated data of the position information of the human body. When the accumulated position information of the human body is determined based on data over a certain period of time, the accuracy of the occupant's actual life area and non-living area may be improved.
The controller 500 may perform a step S300 of controlling the airflow for each outlet.
The controller 500 may set the outlet disposed in a direction toward the living area as the first area outlet 124-1, and set the outlet disposed in a direction toward the non-living area as the second area outlet 124-2, among the plurality of outlets formed in the air conditioner.
The controller 500 controls the wind adjuster 130 so that the airflow of the air discharged from the first area outlet 124-1 and the airflow of the air discharged from the second area outlet 124-2 are set differently in the up-and-down side direction.
The wind adjuster 130 may be divided into a first area wind adjuster 130 disposed in the first area outlet 124-1, and a second area wind adjuster 130 disposed in the second area outlet 124-2.
The step S300 of adjusting the wind adjuster may maintain the airflow discharged from the second area outlet 124-2 uniformly, and may form the airflow discharged from the first area outlet 124-1 to be higher or lower than the air flow discharged from the second area outlet 124-2.
The step S300 of controlling the airflow for each outlet may include a step S310 of detecting the temperature of the indoor space by a temperature sensor, and a step S320 of determining whether the temperature of the indoor space detected by the temperature sensor is included in the set temperature range.
When the temperature of the indoor space detected by the temperature sensor 520 is within the set temperature range, the wind adjuster 130 may be controlled so that the airflow of the air discharged from the first area outlet 124-1 is set to be higher than the airflow of the air discharged from the second area outlet 124-2 (S330). That is, referring to FIGS. 5A and 5B, the wind adjuster 130 may be controlled so that the air discharged from the second area outlet 124-2 flows in the third direction D3, and the air discharged from the first area outlet 124-1 flows in the first direction D1.
In addition, when the temperature of the indoor space detected by the temperature sensor 520 is beyond the set temperature range, the wind adjuster 130 may be controlled so that the airflow of the air discharged from the first area outlet 124-1 is formed to be lower than the airflow of the air discharged from the second area outlet 124-2 (S340). That is, referring to FIGS. 5A and 5B, the wind adjuster 130 may be controlled so that the air discharged from the second area outlet 124-2 flows in the third direction D3, and the air discharged from the first area outlet 124-1 flows in the second direction D2.
However, when a user sets an indirect wind as a preferred wind, the wind adjuster 130 may be controlled so that the air discharged from the first area outlet 124-1 flows in the first direction D1, and the air discharged from the second area outlet 124-2 flows in the second direction D2. The user may set a preferred wind through an input unit such as a remote control (not shown). Here, the indirect wind refers to a case in which a vane is disposed so that the air flow is not directly transmitted to a user.
When the user sets the indirect wind as the preferred wind, only an indirect air flow is set in the first area outlet 124-1 for discharging air to the living area. Accordingly, the first area outlet 124-1 discharges air in the first direction D1. However, when the indoor temperature is beyond the set temperature range, the second area outlet 124-2 for discharging air to the non-living area may discharge air in the second direction D2 so as to quickly reach the set temperature.
The step S300 of adjusting the wind adjuster may maintain the airflow discharged from the second area outlet 124-2 uniformly, and may form the airflow discharged from the first area outlet 124-1 to be higher or lower than the air flow discharged from the second area outlet 124-2.

Hereinafter, a configuration of an air conditioner 200 according to a second embodiment will be described with reference to FIGS. 14 and 15C.
The air conditioner 200 according to the second embodiment is different from the air conditioner 100 according to the first embodiment in a configuration of a wind adjuster 230.
Accordingly, for the remaining configuration excluding the wind adjuster 230, the description of the air conditioner 100 according to the first embodiment may be substituted.
The wind adjuster 230 of the air conditioner 200 according to the second embodiment includes one vane 240 disposed in each outlet 224, and a vane motor (not shown) for driving the vane 240. The disposition of the vane 240 is varied by the operation of the vane motor.
Referring to FIGS. 15A to 15C, the wind adjuster 230 may adjust the wind direction of the air flowing through an outlet 224 by varying the inclination angle of the vanes 240 disposed in the outlet 224. The vane 240 is disposed to close the outlet 224, or to control the wind direction of the air flowing through the outlet 224.
Referring to FIG. 15A, the wind adjuster 230 may be disposed in a first position P1 in which the vane 240 is disposed substantially parallel to a virtual horizontal line parallel to a ground. When the wind adjuster 230 is disposed in the first position P1, the vanes 240 may form an inclination angle θ within 30 degrees for a virtual horizontal line HL. The inclination angle θ is formed between the vane 240 and the virtual horizontal line HL, and may vary depending on the disposition of the vane 240.
Referring to FIG. 15B, the wind adjuster 230 may be disposed in a second position P2 in which the vane 240 is disposed substantially perpendicular to a horizontal line parallel to a ground. When the wind adjuster 230 is disposed in the second position P2, an inclination angle θ of 60 degrees or more may be formed for the virtual horizontal line HL.
Referring to FIG. 15C, the wind adjuster 230 may be disposed in a third position P3 in which the vane 240 forms an angle between the first position P1 and the second position P2. When the wind adjuster 230 is disposed in the third position P3, an inclination angle θ of 30 degrees or more and 60 degrees or less may be formed for the virtual horizontal line HL.
When the wind adjuster 230 is disposed in the first position P1, an indirect wind that sends the air discharged through the outlet in a direction horizontal to a ground may be formed. When the wind adjuster 230 is disposed in the second position P2, a vertical wind that sends the air discharged through the outlet in a direction perpendicular to the ground may be formed. When the wind adjuster 230 is disposed in the third position P3, an inclined wind that sends the air discharged through the outlet into between the indirect wind and the vertical wind may be formed.
As in FIGS. 5A to 5B, the air conditioner according to the second embodiment may also send the air discharged from the outlet 224 in the first direction D1, the second direction D2, and the third direction D3, according to the first position P1, the second position P2, and the third position P3 of the wind adjuster 230.

Hereinafter, the configuration of the air conditioner according to a third embodiment will be described with reference to FIGS. 16 to 17C.
An air conditioner 300 according to the third embodiment is different from the air conditioner according to the first embodiment in the configuration and operation structure of the wind adjuster. In addition, the shape of outlet and the disposition of vane are different. Accordingly, the remaining configuration excluding the shape of outlet and the wind adjuster may be replaced with the description of the air conditioner according to the first embodiment.
In the air conditioner 300 according to the third embodiment, a plurality of outlets 324 are formed in the outer circumference of an inlet 322. Here, the inlet 322 has a rectangular shape, and an outlet 324 is formed to be spaced apart from each side forming the inlet 322 to the outside. In addition, the inlet 322 may also have a circular shape. At this time, a plurality of outlets 324 may be formed in a position spaced apart from each other in a radial direction from the outer circumference of the circular inlet 322.
In the outlet 324 formed in the air conditioner 300 according to the third embodiment, an outer end 324b is disposed in the upper side than an inner end 324a. In addition, a discharge flow path 335 formed in the upper side of the outlet 324 has a structure extending outwardly as it progresses from the upper side to the lower side.
The wind adjuster 350 of the air conditioner according to the third embodiment includes a vane 340 which is disposed in the panel 320, and protrudes with a variable length to the outlet 324, a vane motor (not shown) which is disposed in the panel 320, and drives the vane 340, and a vane gear 350 which rotates by the vane motor, and is engaged with the vane 340 to move the disposition of the vane 340.
One end of the vane 340 engaged with the vane gear 350 may have a rack gear structure.
The vane 340 is disposed in the inner end 324a of the outlet 324. The vane 340 is disposed to protrude outward from the inner end 324a of the outlet 324. The length of the vane 340 protruding to the outlet 324 is varied by the operation of the vane motor.
The wind adjuster 330 may adjust the wind direction of the air flowing through the outlet 324 according to the length of the vane 340 protruding to the outlet 324.
Referring to FIGS. 17A to 17C, the wind adjuster 330 may adjust the wind direction of the air flowing through the outlet 324, by varying the length of the vane 340 protruding to the outlet 324.
Referring to FIG. 17A, the wind adjuster 330 may be disposed in a first position P1 in which the vane 340 protrudes to the outlet 324 to the maximum. When the wind adjuster 330 is disposed in the first position P1, the vane 340 may protrude to the maximum of the protruding range. Accordingly, when the wind adjuster 330 is disposed in the first position P1, the air flowing through the discharge flow path 335 may be guided in a direction horizontal to a ground. When the wind adjuster 330 is disposed in the first position P1, the vanes 340 is disposed to be lower than the outer end 324b of the outlet 324. Therefore, the air discharged through the outlet 324 may flow in a direction horizontal to the ground along the vane 340.
Referring to FIG. 17B, the wind adjuster 330 may be disposed in a second position P2 in which the vane 340 does not protrude to the outlet 324. When the wind adjuster 330 is disposed in the second position P2, it is disposed so as not to be exposed to the outlet 324. Accordingly, when the wind adjuster 330 is disposed in the second position P2, the air flowing through the discharge flow path 335 may be discharged in a direction substantially perpendicular to a ground through the outlet 324. However, according to the shape of the discharge flow path 335, the air flowing through the outlet 324 is able to flow at some oblique angles to the ground.
Referring to FIG. 17C, the wind adjuster 330 is disposed in a third position P3 in which it protrudes to be shorter than a protrusion length of the vane 340 which is disposed in the first position P1. When the wind adjuster 330 is disposed in the third position P3, the vane 340 protrudes to be longer than the length of the vane 340 protruding to the outlet 324 in the second position P2. When the wind adjuster 330 is disposed in the third position P3, it may protrude with a length of 1/3 to 2/3 of a length of the vane 340 protruding to the outlet 324 when the wind adjuster 330 is disposed in the second position P2.
When the wind adjuster 330 is disposed in the first position P1, an indirect wind that sends the air discharged through the outlet in a direction horizontal to the ground may be formed. When the wind adjuster 330 is disposed in the second position P2, a vertical wind that sends the air discharged through the outlet in a direction perpendicular to the ground may be formed. When the wind adjuster 330 is disposed in the third position P3, an inclined wind that sends the air discharged through the outlet into between the indirect wind and the vertical wind may be formed.
As in FIGS. 5A to 5B, the air conditioner according to the third embodiment may also send the air discharged from the outlet 324 in the first direction D1, the second direction D2, and the third direction D3, according to the first position P1, the second position P2, and the third position P3 of the wind adjuster 330.

Hereinafter, the configuration of the air conditioner according to a fourth embodiment will be described with reference to FIGS. 18 to 19C.
An air conditioner 400 according to the fourth embodiment is different from the air conditioner 100 according to the first embodiment in the configuration of the wind adjuster. In the air conditioner according to the fourth embodiment, an inlet 422 may have a circular shape, and an outlet 424 may be formed in an annular shape around the inlet 422.
The wind adjuster 430 of the air conditioner according to the fourth embodiment includes a wind direction adjusting fan 440 disposed in one side of the outlet 424. The wind direction adjusting fan 440 may be disposed in one side of the direction in which the inlet 422 is disposed in an area where the outlet 424 is formed, thereby adjusting the wind direction of the air discharged through the outlet 424.
The wind direction adjusting fan 440 is disposed in one side of the outlet 424 to control the wind direction of the air discharged through the outlet 424. A plurality of wind direction adjusting fans 440 are spaced apart along the circumferential direction of the annular shape in which the outlet 424 is formed.
The wind direction adjusting fan 440 may adjust the wind direction of the air flowing to the outlet 424 by changing the pressure by sucking the air around the outlet 424. The wind direction adjusting fan 440 may control the suction amount of air around the outlet 424.
The wind adjuster 430 may adjust the wind direction of the air discharged through the outlet 424 by adjusting or stopping the rotation speed of the wind direction adjusting fan 440. When the wind direction adjusting fan 440 is stopped, the air flowing to the outlet 424 is affected by the shape of a discharge flow path 425 and the opening direction of the outlet 424. Accordingly, when the wind direction adjusting fan 440 is stopped, the air flowing through the outlet 424 may be discharged in a direction perpendicular to the ground.
However, when the wind direction adjusting fan 440 is operated, a portion of the air discharged through the outlet 424 is affected by the wind direction adjusting fan 440. Therefore, the air discharged through the outlet 424 may be inclined in a direction horizontal to the ground to flow. In this case, the flow direction of the air flowing through the outlet 424 may be adjusted according to the amount of air sucked into the wind direction adjusting fan 440. When the rotation speed of the wind direction adjusting fan 440 is increased, the amount of air sucked into the wind direction adjusting fan 440 is increased, so that air can flow in a direction parallel to the ground.
Referring to FIGS. 19A to 19C, the wind adjuster 430 may adjust the wind direction of the air discharged through the outlet 424 by adjusting the operation or rotation speed of the wind direction adjusting fan 440.
Referring to FIG. 19A, the wind adjuster 430 may rotate at a first set speed for rotating the rotation speed of the wind direction adjusting fan 440 to a maximum value. When the wind adjuster 430 rotates at the first set speed, an indirect wind that sends the air discharged through the outlet in a direction horizontal to the ground may be formed.
Referring to FIG. 19B, the wind adjuster 430 may rotate at a second set speed for rotating the wind direction adjusting fan 440 to a minimum value or for stopping the rotation. Here, the second set speed corresponds to a speed including '0'. Accordingly, the second set speed of the wind adjuster 430 may include a state in which the wind direction adjusting fan 440 is stopped. When the wind adjuster 430 rotates at the second set speed, a vertical wind that sends the air discharged through the outlet in a direction perpendicular to the ground may be formed.
Referring to FIG. 19C, the wind adjuster 430 may rotate at a third set speed for rotating the wind direction adjusting fan 440 at the rotation speed in a range between the first set speed and the second set speed. When the wind adjuster 430 rotates at the third set speed, an inclined wind that sends the air discharged through the outlet into between the indirect wind and the vertical wind may be formed.
When the wind adjuster 430 rotates at the first rotation speed which is the maximum speed, the indirect wind that sends the air discharged through the outlet in a direction horizontal to the ground may be formed. When the wind adjuster 430 rotates at the second set speed for rotating the wind direction adjusting fan 440 to a minimum value or for stopping the rotation, the vertical wind that sends the air discharged through the outlet in a direction perpendicular to the ground may be formed. When the wind adjuster 430 rotates at the third rotation speed corresponding to between the first rotation speed and the second rotation speed, the inclined wind that sends the air discharged through the outlet into between the indirect wind and the vertical wind may be formed.
