Description

Air Processing Apparatus

The present invention relates to an air processing device, and to an air processing device including a louver that adjusts the wind direction of air discharged through an outlet.

Air treatment devices, including air conditioners or air purifiers, can control indoor temperature or remove fine dust from indoor air.

An air treatment device installed on the ceiling or on the upper side of a wall forms long discharge ports in the left and right directions. Additionally, the air treatment device disposed on the ceiling or upper side of the wall includes a louver and a louver drive device that changes the arrangement of the louvers to adjust the wind direction of the air discharged from the discharge ports formed in the left and right directions.

Publication patent KR 10-2018-0066546 discloses an air treatment device that adjusts the wind direction of discharged air by changing the arrangement of vanes. However, since the drive motor that changes the arrangement of the vanes is disposed on one side of the vane in the left and right directions, the discharge port may not be formed in the portion where the drive motor is disposed. This causes a problem in that the area of the discharge port is relatively reduced.

The problem to be solved by the present invention is to provide an air treatment device having a structure that has a louver and a louver driving device that can expand the discharge port to the maximum in an air processing device that forms an outlet in the left and right directions.

Another object of the present invention is to provide an air treatment device that increases the range of controlling the wind direction of air with a louver.

Louvers that are long in the left and right directions may be relatively weak against distortion. Another object of the present invention is to provide an air treatment device including a louver with a stable structure.

Another object of the present invention is to provide an air treatment device that stably limits the movement of louvers.

The problems of the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

In order to achieve the above object, an air treatment device according to an embodiment of the present invention includes a case in which an outlet is formed, a louver rotatably disposed in the case and controlling the wind direction of air flowing through the outlet, and the louver It includes a louver driving device that adjusts the arrangement, wherein the louver includes a plurality of vanes spaced apart in the radial direction based on the louver rotation axis, and the louver driving device includes a vane disposed at the outermost of the plurality of vanes. By changing the arrangement of the louver, the discharge port can be secured as much as possible in the left and right directions.

The louver includes a louver rotation axis extending along the rotation center of the louver, an outer vane disposed radially outwardly from the louver rotation axis, and disposed between the louver rotation axis and the outer vane, and spaced apart from each other in the radial direction. It includes a plurality of inner vanes, and the louver driving device is connected to the louver driving device on the outer peripheral surface of the outer vane, so that the louver driving device may be disposed radially outside the rotation axis of the louver.

A vane gear is formed on the outer peripheral surface of the outer vane in the circumferential direction, and the louver driving device engages the vane gear to rotate the louver, so that the louver driving device can be disposed on the radial outer side of the louver rotation axis.

The outer vane has an arc shape extending in the circumferential direction based on the louver rotation axis, and can change the arrangement of the louver and change the wind direction of the discharged air.

The plurality of inner vanes have a shorter length than the outer vanes. That is, the outer vanes may be formed larger than the inner vanes to change the arrangement of the louvers and control the wind direction of the air.

Each of the plurality of inner vanes has different lengths.

The plurality of inner vanes are formed to be longer in length as they are arranged closer to the louver rotation axis. In other words, the length becomes shorter as it is placed adjacent to the outer vane, thereby preventing the flow path between the outer vane and the inner vane from being reduced.

The distance between the outer vane and the plurality of inner vanes becomes farther from the upper side to the lower side.

Each of the plurality of inner vanes includes a lower inner vane portion inclined to be adjacent to the louver rotation axis as it goes downward, and an upper inner vane portion that is bent at the top of the lower inner vane and extends upward. This takes into account the direction in which the lower part of the inner vane, which guides the air discharged according to the arrangement of the louvers, faces.

The louver includes an axis vane extending from the louver rotation axis, and the axis vane extends in a direction parallel to the lower part of the inner vane, so that it can effectively guide the wind direction of air flowing along the louver rotation axis.

Including the support panel on which the gear is placed, a plurality of vanes can be stably arranged.

The louver driving device is spaced apart from the louver rotation axis in a centrifugal direction and is placed in contact with the outer peripheral surface of the louver. That is, the louver driving device for rotating the louver is not disposed on the side of the louver, so the louver can be expanded to the left and right sides of the discharge port.

The louver driving device includes a louver gear that engages one side of the louver and rotates the louver, and a louver motor that rotates the louver gear.

The louver driving device includes a pair of louver gears that are spaced apart from each other and engage with one side of the louver to rotate the louver, a gear rotation shaft connecting the pair of louver gears, and a gear rotation shaft connected to the gear rotation shaft. Including a louver motor that rotates the rotation axis, louvers formed long in the left and right directions can be easily rotated.

The case includes an upper cover, a lower cover disposed on a lower side of the upper cover, a rear cover that forms the inlet and is equipped with the filter device, and a front cover that is spaced forward from the rear cover. , the louver is rotatably disposed at the bottom of the front cover and can discharge air toward the bottom or front of the case.

The front cover may include a louver protrusion in which a louver groove is formed to control the rotation range of the louver and where the louver rotation axis is disposed, thereby limiting the rotation range of the louver.

The louver protrusion includes an upper protrusion forming a surface inclined from the upper side of the louver groove to the rear upper side, and a lower protrusion forming a surface inclined from the lower side of the louver groove to the front lower side, allowing the rotation of the louver in both directions. It can be limited.

Specific details of other embodiments are included in the detailed description and drawings.

According to the air conditioning system of the present invention, one or more of the following effects are achieved.

First, the louver driving device that drives the louver is connected to the louver on the radial outer side of the rotation axis of the louver, so that the louver can be expanded in the left and right directions. This can secure the maximum size of the discharge port in the left and right directions. This has the advantage of being able to maximize the volume of air discharged from the air treatment device, allowing the air in the indoor space to be treated quickly.

Second, since the outer vane has an arc shape and is spaced apart from the louver rotation axis, the range in which the outer vane protrudes to the outside of the discharge opening or moves inside the discharge opening increases, so that the wind direction of the discharged air can be increased.

Third, the louver has a structure that includes a plurality of vanes and a support panel, and is connected to the louver driving device at the support panel, so that the rigidity of the louver can be secured, so the louver has the advantage of being able to change the arrangement stably. there is.

Fourth, the louver groove formed in the case at the portion where the rotation axis of the louver is located includes upper and lower protrusions that limit the rotation of the louver, so there is also the advantage of stably limiting the rotation of the louver.

Since the first air processing device and the second air processing device are arranged in the left and right directions, and the louvers placed at each discharge port are individually driven, the discharge direction is individually adjusted in consideration of the temperature of the discharged air, thereby increasing the space inside the room. It also has the advantage of speeding up air circulation.

Third, the louver disposed at the discharge port of each of the first air processing device and the second air processing device has a louver rotation axis disposed on the front side, and a louver driving device is disposed at a position radially spaced from the louver rotation axis. This has the advantage that since the louver driving device is not disposed in the left and right directions of the louver, the louver can be disposed in the entire left and right directions of the discharge port, making the best use of the discharge port area through which air is discharged.

Fourth, the pre-filter disposed in each of the first and second air treatment devices can be cleaned with a single filter cleaner, which has the advantage of keeping each pre-filter clean.

Fifth, the filter device disposed in the second air treatment device can be moved up and down by the filter driving device, which has the advantage of allowing users to easily access the filter device.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.
