Patent Description:
An air-processing apparatus may conceptually include an air conditioner for adjusting indoor temperature and an air purifier for removing fine dust from indoor air.

In the case of an air conditioner, a stand-type indoor unit, a wall-mounted indoor unit, or a ceiling-mounted indoor unit may be mounted in an indoor space in order to adjust the temperature of the indoor space.

An air purifier is generally configured to be movable, and is disposed on the floor of an indoor space in order to purify contaminated air in the indoor space.

Because an air conditioner and an air purifier are physically separated from each other and are located at different positions, the region in which the air conditioner discharges heat-exchanged air and the region in which the air purifier discharges purified air may differ from each other.

In order to address this problem, a filter may be disposed in the inlet region of the air conditioner. However, when a high-efficiency particulate air (HEPA) filter for use in an air purifier is mounted in the air conditioner, the HEPA filter acts as resistance to the flow of air to a heat exchanger. Therefore, it is difficult to use a HEPA filter in an air conditioner.

<CIT> discloses a structure in which a separate air conditioner is disposed in a lower space in a stand-type air conditioner. This structure enables individual air conditioning for a lower region and an upper region in an indoor space. However, it is difficult to perform air conditioning and air purification for overlapping regions.

A ceiling-mounted air-processing apparatus or a wall-mounted air-processing apparatus has an outlet formed to be long in a leftward-rightward direction. In addition, this type of air-processing apparatus includes a louver for adjusting the direction of air blown out from the outlet formed in the leftward-rightward direction and a louver actuator for changing the orientation of the louver.

<CIT> discloses an air-processing apparatus capable of adjusting the direction of air that is blown out by changing the orientation of a vane. However, a driving motor for changing the orientation of the vane is disposed on the left or right side of the vane, and thus an outlet may not be formed in the portion in which the driving motor is disposed, which may incur a problem in which the area of the outlet is comparatively reduced.

It is an object of the present invention to provide an air-conditioning system capable of simultaneously supplying heat-exchanged air and purified air to an indoor space.

It is another object of the present invention to provide an air-conditioning system capable of rapidly circulating heat-exchanged air and purified air in an indoor space.

It is still another object of the present invention to provide an air-processing apparatus including a louver and a louver actuator capable of opening an outlet, which is formed in the air-processing device in a leftward-rightward direction, to the maximum extent.

It is still another object of the present invention to provide an air-processing apparatus capable of increasing the range within which the direction of air is capable of being adjusted by a louver.

A louver, which is formed to be long in the leftward-rightward direction, may be relatively susceptible to distortion. It is still another object of the present invention to provide an air-processing apparatus including a louver having a stable structure.

It is still another object of the present invention to provide an air-processing apparatus capable of stably restricting movement of a louver.

The invention is defined in the independent claim. Dependent claims describe preferred embodiments.

In order to accomplish the above and other objects, an air-processing apparatus according to an embodiment of the present invention includes a case having an outlet formed therein, a louver rotatably disposed in the case and configured to adjust the direction of air flowing through the outlet, and a louver actuator configured to adjust the orientation of the louver. The louver includes a louver rotation shaft and a plurality of vanes disposed so as to be spaced apart from each other in a radial direction based on the louver rotation shaft. The louver actuator is disposed so as to be in contact with the vane located at the outermost position from the louver rotation shaft among the plurality of vanes to change the orientation of the louver. Accordingly, the size of the outlet may be secured in a leftward-rightward direction to the maximum extent.

The louver rotation shaft may extend along the rotation center of the louver. The plurality of vanes may include an outer vane spaced outwards apart from the louver rotation shaft in the radial direction and a plurality of inner vanes disposed between the louver rotation shaft and the outer vane so as to be spaced apart from each other in the radial direction. The louver may be connected at the outer circumferential surface of the outer vane to the louver actuator. The louver actuator may be disposed outside the louver in the radial direction of the louver rotation shaft.

A vane gear may be formed on the outer circumferential surface of the outer vane in a circumferential direction, and the louver actuator may be engaged with the vane gear to rotate the louver. The louver actuator may be disposed outside the louver in the radial direction of the louver rotation shaft.

The outer vane may have an arc shape that extends in the circumferential direction based on the louver rotation shaft. Accordingly, it is possible to change the orientation of the louver and to change the direction of air that is discharged.

The plurality of inner vanes may be shorter than the outer vane. That is, the outer vane may be formed to be larger than the inner vanes in order to change the orientation of the louver and to adjust the direction of air.

Each of the plurality of inner vanes may have a different length from the remaining ones of the plurality of inner vanes.

The lengths of the plurality of inner vanes may gradually increase in a direction approaching the louver rotation shaft. That is, the lengths of the plurality of inner vanes may gradually decrease in a direction approaching the outer vane. Accordingly, it is possible to prevent a reduction in the size of a flow path between the outer vane and the inner vanes.

The spacing distance between the outer vane and each of the plurality of inner vanes may gradually increase from above to below.

Each of the plurality of inner vanes may include a lower inner vane portion formed to be inclined so as to be gradually closer to the louver rotation shaft in a downward direction and an upper inner vane portion formed to be bent and extend upwards from the upper end of the lower inner vane portion. This structure is determined in consideration of the direction in which the lower inner vane portion for guiding air that is discharged is oriented according to a change in the orientation of the louver.

The louver may include an axial vane extending from the louver rotation shaft, and the axial vane may extend in a direction parallel to the lower inner vane portion. Accordingly, it is possible to effectively guide the direction of air that flows along the louver rotation shaft.

The louver may include a pair of end panels disposed at both ends of the plurality of vanes in a direction perpendicular to the plurality of vanes and a support panel disposed between the pair of end panels and provided at one side thereof with a vane gear. The vane gear may be engaged with the louver actuator. Accordingly, the plurality of vanes may be stably disposed.

The louver actuator may be spaced apart from the louver rotation shaft in a centrifugal direction, and may be disposed so as to be in contact with the outer circumferential surface of the louver. That is, the louver actuator for rotating the louver may not be disposed on the side surface of the louver, and thus the size of the louver may increase to the left and right surfaces of the outlet.

The louver actuator may include a louver gear configured to be engaged with one side of the louver to rotate the louver and a louver motor configured to rotate the louver gear.

The louver actuator may include a pair of louver gears arranged so as to be spaced apart from each other and engaged with one side of the louver to rotate the louver, a gear rotation shaft interconnecting the pair of louver gears, and a louver motor connected to the gear rotation shaft to rotate the gear rotation shaft. Accordingly, it is possible to easily rotate the louver, which is formed to be long in the leftward-rightward direction.

The case may include an upper cover, a lower cover disposed below the upper cover, a rear cover forming an inlet and supporting the filter device mounted thereto, and a front cover disposed so as to be spaced forwards apart from the rear cover. The louver may be rotatably disposed at the lower end of the front cover. Accordingly, it is possible to discharge air in the downward direction or the forward direction of the case.

The front cover may include a louver protrusion having formed therein a louver groove in which the louver rotation shaft is disposed in order to limit a range within which the louver rotates.

The louver protrusion may include an upper protruding portion forming a surface that is inclined from the upper end of the louver groove in a rearward-upward direction and a lower protruding portion forming a surface that is inclined from the lower end of the louver groove in a forward-downward direction. Accordingly, it is possible to limit the rotation of the louver in both directions.

The details of other aspects will be included in the detailed description and the drawings below.

As is apparent from the above description, the air-conditioning system of the present invention has one or more effects as follows.

First, since an air-processing apparatus for discharging heat-exchanged air and an air-processing apparatus for discharging purified air are arranged in series in the leftward-rightward direction, it is possible to simultaneously perform air purification and temperature control in an indoor space.

Second, since the first air-processing apparatus and the second air-processing apparatus are arranged in the leftward-rightward direction and the louvers disposed in the outlets of the first and second air-processing apparatuses are individually operated, it is possible to individually adjust the directions of air discharged therefrom in consideration of the temperature of air that is discharged, thereby promoting air circulation in an indoor space.

Third, since the louver actuator for driving the louver is disposed outside in the radial direction of the rotation shaft of the louver, the size of the louver may increase in the leftward-rightward direction. Accordingly, it is possible to secure the size of the outlet in the leftward-rightward direction to the maximum extent. Accordingly, the amount of air that is discharged from the air-processing apparatus may be maximized, and thus the air in the indoor space may be rapidly processed.

Fourth, since the outer vane has an arc shape and is spaced apart from the louver rotation shaft, the range within which the outer vane can protrude outside the outlet or can move inside the outlet may increase, thereby increasing the angular range within which air is discharged.

Fifth, the louver has a structure including a plurality of vanes and a support panel, and is connected to the louver actuator at the support panel. Accordingly, the rigidity of the louver may increase, and thus the orientation of the louver may be stably changed.
