Description

Technical Field

[0001] The present invention relates to an air treatment device, in particular to an air treatment device including a louver for adjusting the wind direction of air discharged from a discharge port. Background Art

[0002] The air treatment device includes an air conditioner or an air purifier, which can adjust the indoor temperature or remove dust from the indoor air.

[0003] In the case of air conditioners, indoor units such as floor-standing indoor units, wall-mounted indoor units, and ceiling-mounted indoor units are placed in indoor spaces and can adjust the temperature of the indoor spaces.

[0004] An air purifier is mainly configured to be movably disposed on a floor of an indoor space, and can purify polluted air in the indoor space.

[0005] Since the air conditioner and the air purifier are physically configured to be separated from each other, there may be a difference between an area where the air conditioner discharges heat-exchanged air and an area where the air purifier discharges filtered air.

[0006] To solve this problem, a filter can be placed in the air conditioner's inlet region. However, if a high-efficiency air filter used in an air purifier is placed in the air conditioner, resistance to the flow of air to the heat exchanger is created, making it difficult to use.

[0007] Korean Patent Publication No. KR 2012-0034446 proposes a structure in which an additional air conditioner is placed in the space below a floor-standing air conditioner. However, while this structure is suitable for air conditioning the space separated into lower and upper areas, it has the problem of difficulty in temperature control and air purification in the overlapping space.

[0008] The air handling device, mounted on the ceiling or on the upper side of the wall, forms a long discharge port extending in the left-right direction. Furthermore, the air handling device, mounted on the ceiling or on the upper side of the wall, includes louvers and a louver drive device for changing the arrangement of the louvers to adjust the direction of air discharged from the discharge port formed in the left-right direction.

[0009] Korean Patent Publication No. KR 10-2018-0066546 discloses an air treatment device that adjusts the direction of discharged air by changing the arrangement of blades. However, because the drive motor that changes the blade arrangement is located on one side of the blades, it may not be possible to form an outlet in the area where the drive motor is located. This results in a relatively small outlet area. Summary of the Invention

[0010] An object of the present invention is to provide an air-conditioning system that simultaneously supplies temperature-regulated air and purified air to an indoor space.

[0011] Another object of the present invention is to provide an air-conditioning system capable of quickly circulating temperature-regulated air and filtered air in a room.

[0012] Another object of the present invention is to provide an air handling device having a discharge port formed in the left-right direction, the air handling device including a louver and a louver driving device configured to maximize the discharge port.

[0013] Another object of the present invention is to provide an air handling device that utilizes louvers to increase the range of air direction adjustment.

[0014] Louvers that are formed long in the left-right direction may be relatively fragile in terms of twisting. Another object of the present invention is to provide an air treatment device including louvers having a stable structure.

[0015] Another object of the present invention is to provide an air handling device that stably restricts movement of louvers.

[0016] The subjects of the present invention are not limited to the above-mentioned subjects, and those skilled in the art can clearly understand other subjects not mentioned through the following description.

[0017] In order to achieve the above-mentioned problems, an air treatment device according to an embodiment of the present invention includes: a shell having an outlet formed thereon; a louver rotatably arranged on the shell to adjust the wind direction of the air flowing through the outlet; and a louver driving device to adjust the arrangement of the louver, wherein the louver includes a plurality of blades radially spaced apart with respect to a louver rotation axis, and the louver driving device contacts the outermost blades among the plurality of blades, thereby changing the arrangement of the louver to ensure the outlet to the maximum extent in the left and right directions.

[0018] The louver includes: a louver rotation shaft extending along the rotation center of the louver; outer blades spaced apart from the louver rotation shaft toward the radial outside; and a plurality of inner blades arranged between the louver rotation shaft and the outer blades, and spaced apart from each other along the radial direction. The louver driving device is connected to the blade teeth on the outer peripheral surface of the outer blade, so that the louver driving device can be arranged radially outside the rotation shaft of the louver.

[0019] Blade teeth are formed on the outer peripheral surface of the outer blade along the circumferential direction, and the louver driving device engages with the blade teeth to rotate the louver. The louver driving device can be arranged radially outside the louver rotation shaft.

[0020] The outer blades have an arc shape extending in a circumferential direction with the louver rotation axis as a reference, so that the wind direction of the discharged air can be changed by changing the arrangement of the louvers.

[0021] The plurality of inner blades are shorter than the outer blades. That is, the outer blades can be formed to be larger than the inner blades in order to change the arrangement of the louvers and adjust the wind direction of the air.

[0022] The plurality of inner blades have different lengths from each other.

[0023] The plurality of inner blades are formed so that their length increases as they get closer to the louver rotation axis, that is, their length decreases as they get closer to the outer blades, thereby preventing the flow path between the outer blades and the inner blades from becoming shorter.

[0024] The interval between the outer blade and each of the plurality of inner blades increases as going from the upper side to the lower side.

[0025] Each of the plurality of inner blades includes a lower portion that is tilted downwardly toward the louver rotation axis, and an upper portion that curves upward at the upper end of the lower portion. This is to ensure the direction in which the lower portion of the inner blade faces when guiding the discharged air, depending on the arrangement of the louvers.

[0026] The louver includes an axial blade extending from the louver rotation axis. The axial blade extends in a direction parallel to the lower portion of the inner blade, thereby effectively guiding the wind direction of air flowing along the louver rotation axis.

[0027] The louver includes: a pair of end panels, which are arranged at both ends of a plurality of blades and arranged along a direction perpendicular to the plurality of blades; and a supporting panel, which is arranged between the pair of end panels, and blade teeth that engage with the louver driving device are arranged on one side of the supporting panel, so that the plurality of blades can be stably arranged.

[0028] The louver driving device is arranged centrifugally away from the louver rotating shaft and contacts the outer peripheral surface of the louver. That is, the louver driving device for rotating the louver is not arranged on the side of the louver, so that the louver can expand to the left and right sides of the discharge port.

[0029] The shutter driving device includes: a shutter gear engaged with one side of the shutter to rotate the shutter; and a shutter motor to rotate the shutter gear.

[0030] The shutter driving device includes: a pair of shutter gears, which are arranged to be separated from each other and engage with one side of the shutter to rotate the shutter; a gear rotating shaft, which connects the pair of shutter gears; and a shutter motor, which is connected to the gear rotating shaft and rotates the gear rotating shaft, so that the shutter formed long along the left and right directions can also be easily rotated.

[0031] The shell includes: an upper cover; a lower cover, which is arranged on the lower side of the upper cover; a rear cover, which forms the suction port and is equipped with a filter device; and a front cover, which is separated from the rear cover and arranged forward, and the louver is rotatably arranged at the lower end of the front cover so that air can be discharged toward the lower side or front direction of the shell.

[0032] The front cover includes a louver protrusion, which adjusts the rotation range of the louver and forms a louver groove for the louver rotation axis to be configured, thereby limiting the rotation range of the louver.

[0033] The louver protrusion includes: a protrusion upper portion, forming a surface inclined from the upper side of the louver groove to the rear upper side; and a protrusion lower portion, forming a surface inclined from the lower side of the louver groove to the front lower side, thereby being able to limit the rotation of the louver in two directions.

[0034] Details of other embodiments are included in the detailed description and accompanying drawings.

[0035] The air conditioning system according to the present invention has one or more of the following effects.

[0036] First, an advantage is that by arranging the air handling device that discharges temperature-regulated air and the air handling device that discharges filtered air side by side in the left-right direction, it is possible to simultaneously perform air purification and temperature regulation in the indoor space.

[0037] Second, the advantage is that since the first air treatment device and the second air treatment device are arranged in the left-right direction, the louvers arranged at each outlet are driven individually. Therefore, considering the temperature of the discharged air, the discharge direction can be adjusted individually, thereby accelerating the air circulation in the indoor space.

[0038] A third advantage is that the louver drive device that drives the louvers is connected to the louvers radially outward from the louver's rotation axis, allowing the louvers to expand horizontally. This maximizes the horizontal dimension of the outlet. This maximizes the volume of air discharged from the air handling unit, allowing for rapid treatment of the air in the indoor space.

[0039] Fourth, since the outer blades have an arc shape and are spaced apart from the louver rotation axis, the outer blades have a greater range of protruding outward from the discharge port or moving inward from the discharge port, thereby increasing the wind direction of the discharged air.

[0040] Fifth, the advantage is that the louver includes a plurality of blades and has a structure including a support panel. The support panel is connected to the louver driving device, which can ensure the rigidity of the louver, thereby being able to stably change the arrangement of the louver.

[0041] Sixth, an advantage is that the louver groove formed in the housing includes a protruding upper portion and a protruding lower portion for restricting the rotation of the louver at a portion where the rotation shaft of the louver is disposed, thereby stably restricting the rotation of the louver.

[0042] The advantage is that the first air treatment device and the second air treatment device are arranged in the left and right directions, and the louvers arranged at each outlet are driven individually. Therefore, considering the temperature of the discharged air, the discharge direction can be adjusted individually, thereby speeding up the air circulation in the indoor space.

[0043] The effects of the present invention are not limited to the above-mentioned effects, and those skilled in the art can clearly understand other effects not mentioned through the description of the claims. BRIEF DESCRIPTION OF THE DRAWINGS
