FIGS. 2 and 3 are vertical cross-sectional views showing an inner structure of the indoor unit; -
FIG. 4 is a perspective view showing a structure of a guide unit; and -
FIG. 5 is a perspective view showing a structure of a guide unit. - Referring to
FIG. 1 , anindoor unit 10 of an air conditioner includes acabinet 11, afront panel 12, and anintake panel 13. Thecabinet 11 defines an outer appearance of theindoor unit 10 and has an opening at the lower side thereof. As an example, theindoor unit 10 is a ceiling-suspended type air conditioner. Thefront panel 12 is coupled to a lower portion of thecabinet 11. Anintake portion 121 is defined in thefront panel 12. The intake panel is coupled to thefront panel 12 in a manner that enables vertical movement to open or close theintake portion 121. - A body of the
indoor unit 10 may include thecabinet 11 and thefront panel 12. Here, a plurality ofdischarge holes 122 is defined in edge portions of thefront panel 12. Adischarge vane 123 that is rotatable is positioned on thefront panel 12. Thus, a direction of discharged air is adjusted based on a rotation angle of thedischarge vane 123. - When the
indoor unit 10 turns on, theintake panel 13 opens theintake portion 121 by moving toward a bottom of a room (moving down). When theindoor unit 10 turns off, theintake panel 13 closes theintake portion 121 by moving toward the ceiling (moving up). - Referring to
FIGS. 2 to 4 , thecabinet 11 includes a heat-exchanger 17, afan assembly 14, ashroud 16, and afilter 15 therein. Thefan assembly 14 is positioned within an inner space of the heat-exchanger 17. Theshroud 16 is located in a lower side of thefan assembly 14 to guide a flow of air sucked from outside of thecabinet 11. Thefilter 15 is also positioned at the lower side of thefan assembly 14 to filter the sucked air. - An
orifice 124 for guiding an air flow is positioned around theintake portion 121. Thefilter 15 is positioned on an upper portion of theorifice 124. Theorifice 124 is configured to have a round shape from thefront panel 12 toward thefan assembly 14. - A
rack 18 is positioned on an upper portion of theintake panel 13. Apinion 18 a coupled to therack 18 and a drive motor (not shown) for rotating thepinion 18 a. Thepinion 18 a may be positioned on an upper portion of thefront panel 12. - Thus, the
intake panel 13 is vertically moved by an operation of the drive motor, and theintake portion 121 is selectively opened or closed by the movement of theintake panel 13. When theintake portion 121 is opened, theintake panel 13 may cover theintake portion 121 at a position spaced from theintake portion 121. So, theintake portion 121 may be minimally exposed by theintake panel 13. - In this implementation, an ascending/descending unit of the
intake panel 13 is not limited to the above-described rack/pinion structure. The air sucked through theintake portion 121 is filtered of foreign substances by passing through thefilter 15. Then, the filtered air flows toward thefan assembly 14. The fan assembly includes acentrifugal fan 142 that sucks air in an axial direction and discharges air in a radius direction and afan motor 141 for driving thecentrifugal fan 142. Therefore, by driving thecentrifugal fan 142 the air is passed through the heat-exchanger 17 and is discharged again to an indoor room through thedischarge hole 122. - A
guide unit 19 for guiding the flow of the sucked air is positioned between theintake panel 13 and thefilter 15. Theguide unit 19 is configured to be located from theintake panel 13 toward theintake portion 121 or from theintake portion 121 toward theintake panel 13. - At least a portion of the
guide unit 19 is positioned in theintake portion 121 and the portion of theguide unit 19 partitions theintake portion 121 into a plurality of intake passages SP, which in some examples, reduces a flow noise of the air sucked through theintake portion 121. - The
guide unit 19 includes afirst guide part 191 positioned on a top surface (a surface facing the intake portion) of theintake panel 13 and asecond guide part 195 relatively movable with respect to thefirst guide part 191. Thesecond guide part 195 can be positioned on thefront panel 12 as one body. - As shown in
FIG. 4 , thefirst guide part 191 may have a cross shape in section that is perpendicular to a flow direction of air. Thefirst guide part 191 has aninsertion portion 192 such that at least portion of thesecond guide part 195 can be combined with (e.g., inserted in) thefirst guide part 191. So, theinsertion portion 192 is configured to have a shape to be combined with a horizontal section of thesecond guide part 195. - The
first guide part 191 is vertically moved together with theintake panel 13 because thefirst guide part 191 is positioned on a top surface of theintake panel 13. When theintake panel 13 descends or moves down in response to, for example, a turning on of the air conditioner, thefirst guide part 191 also moves down due to its weight. On the contrary, when theintake panel 13 ascends or moves up, theintake panel 13 can lift thefirst guide part 191. - Alternatively, the
first guide part 191 may be assembled with theintake panel 13 as one body. Thesecond guide part 195 is positioned on an inner surface of theorifice 124 as shown inFIG. 4 . For example, thesecond guide part 195 is positioned on theintake portion 121. Like thefirst guide part 191, thesecond guide part 195 may have a cross shape in section that is perpendicular to the flow direction of the air passing through theintake portion 121. - As an example, the
intake portion 121 is partitioned into four intake passages SP as shown inFIG. 4 . - The
second guide part 195 has a cusp-shapedend portion 196 as shownFIG. 2 andFIG. 3 . A thickness of theend portion 196 of thesecond guide part 195 narrows toward thefan assembly 14 such that the air smoothly flows. - Although the
first guide part 191 and thesecond guide part 195 have cross shapes in section that are perpendicular to the flow direction of the air passing through theintake portion 121 respectively, the implementation is not limited to the shape of each of theguide parts guide parts intake portion 121 into the plurality of intake passages. - An operation of the
guide unit 19 will be described below. When theindoor unit 10 turns on, theintake panel 13 descends by the drive motor, and thecentrifugal fan 142 is rotated. - When the
intake panel 13 descends, thefirst guide part 191 descends together with theintake panel 13. Thefirst guide part 191 is positioned on the top surface of theintake panel 13. As thefirst guide part 191 and thesecond guide part 195 are relatively movable with respect to each other, thefirst guide part 191 slides downwardly along an outer surface of thesecond guide part 195. When thefirst guide part 191 is moved downwardly, at least portion of thefirst guide part 191 is located to the outside of theintake portion 121. - As the
first guide part 191 descends, the total height of theguide unit 19 increases. When theintake panel 13 descends, a space S (seeFIG. 2 ) is defined between the top surface of theintake panel 13 and a bottom surface of thefront panel 12, and indoor air flows into the space S. The air flowing into the space S can be sucked into thecabinet 11 through theintake portion 121 under the condition that a flow direction of the air is changed due to the defined space. - The top surface of the
intake panel 13 is substantially horizontal to the bottom surface of thefront panel 12, so the indoor air flows into the space S in a substantially horizontal direction. - If the
guide unit 19 is not provided, the air is concentrated at a central portion of the top surface of theintake panel 13. Thus, air turbulence may occur at the central portion of the top surface of theintake panel 13. As a result, the air may not smoothly flow. - However, when the
guide unit 19 is provided between theintake panel 13 and thefilter 15 or a bottom surface of thefront panel 12, the air flowing into the space S flows along the respective intake passages SP partitioned by theguide unit 19. Thus, occurrence of air turbulence may be reduced at the central portion of the top surface of theintake panel 13. - In addition, since the air flow is guided up to an end portion of the
second part 195, the air is not concentrated until the air flows up to an upper end portion of thesecond guide part 195. - When the
indoor unit 10 turns off, theintake panel 13 ascends by the drive motor. At this time, thefirst guide part 191 ascends along the outside of thesecond guide part 195 and is positioned inside theorifice 124. - Also, as a volume of the
second guide part 195 can be combined with theinsertion portion 192 of thefirst guide part 191, it reduces the possibility of thefirst guide part 191 interfering with thefilter 15. - Here, since the
first guide part 191 is relatively movable with respect to thesecond guide part 195, the total height of theguide unit 19 may be maximized in a state where theintake panel 13 opens theintake portion 121. - The increase of the total height of the
guide unit 19 denotes an increase of a flow distance of the air flowing along the respective intake passages SP partitioned by theguide unit 19. Thus, as the total height of theguide unit 19 increases, the occurrence of the air turbulence may be reduced. - Referring to
FIG. 5 , aguide unit 29 includes afirst guide part 291 positioned on a top surface of anintake panel 13 and asecond guide part 295 that at least portion of thefirst guide part 291 is combined or inserted into. Thesecond guide part 295 can be assembled with afront panel 12 as one body. - The
second guide part 295 has aninsertion portion 296. So, thefirst guide part 291 is inserted into thesecond guide part 295. When theintake panel 13 is vertically moved, thesecond guide part 295 is vertically moved in a state where at least portion of thefirst guide part 291 is inserted into theinsertion portion 296. - Although the guide unit includes two guide parts, the present disclosure is not limited thereto. For example, the guide unit may include three or more guide parts relatively movable with respect to each other.
- It will be understood that various modifications may be made without departing from the spirit and scope of the claims. For example, advantageous results still could be achieved if steps of the disclosed techniques were performed in a different order and/or if components in the disclosed systems were combined in a different manner and/or replaced or supplemented by other components. Accordingly, other implementations are within the scope of the following claims
