Definitions
- the present invention relates to an indoor unit of an air conditioner that blows air sucked from the front in multiple directions.
- a cross-fin heat exchanger and a cross-flow fan have been arranged in a generally rectangular casing mounted on the wall, and air has been sucked in from the front to achieve casing.
- a suction grill is attached to the suction port provided on the front side of the indoor unit.
- an object of the present invention is to provide an indoor unit of an air conditioner that can respond to various demands of pictures and colors according to the interior of a room, the taste of a person, the season, etc. at a low cost, and can easily wipe off dirt. Is to do.
- the indoor unit of the air conditioner of the present invention includes: T
- a turbo fan in which a shaft is disposed in the casing in the front-rear direction and blows air sucked from the front in the axial direction radially outward with respect to the shaft;
- a heat exchanger disposed axially forward of the turbofan in the casing
- a mesh flat plate attached to the suction port of the front panel.
- the turbofan and heat exchanger can be made thinner and the entire indoor unit can be made thinner and the suction port side flat.
- a mesh flat plate can be attached to the suction port instead of the suction grill.
- the design choices will be expanded and the degree of freedom will be increased by separately preparing mesh-shaped flat plates with different patterns and colors.
- the above-mentioned mesh-shaped flat plate can be attached to both the front and back surfaces facing forward.
- two different patterns and colors are applied to the front and back surfaces of the mesh plate, respectively, so that one mesh plate with different patterns and colors can be used separately.
- Two types of mesh flat plate You can select a pattern and color.
- FIG. 1 is an exploded perspective view of an indoor unit of an air conditioner according to an embodiment of the present invention.
- 2 (A) and 2 (B) are a front view and a side view of the indoor unit.
- FIG. 3 is an enlarged view of a main part of the mesh flat plate of the indoor unit.
- FIG. 4 is a sectional view taken along line IV-IV in FIG. 2 (A).
- FIG. 5 is a perspective view showing an example of the indoor unit.
- FIG. 6 is a perspective view showing another example of the indoor unit. BEST MODE FOR CARRYING OUT THE INVENTION
- FIG. 1 is an exploded perspective view of an indoor unit of an air conditioner according to an embodiment of the present invention, in which 1 is a rear surface side mounted on an indoor wall surface, and four outlets la (FIG. 1 shows only two outlets la). ), A front panel having a suction port 2a attached to the casing 1 and opening toward the front, 3 a filter mounted on a suction port 2a of the front panel 2, 4 A mesh-shaped flat plate attached to the suction port 2a of the front panel 2 and on the front side of the filter 3, and 5 is an attachment for fixing the filter 3 and the mesh-shaped flat plate 4 to the suction port 2a of the front panel 2 It is a frame.
- FIG. 2 (A) is a front view of the indoor unit
- FIG. 2 (B) is a side view of the indoor unit.
- the mesh flat plate 4 covers the suction port 2a (shown in FIG. 1) of the front panel 2.
- FIG. 3 is an enlarged view of a main part of the mesh-shaped flat plate 4.
- the mesh-shaped flat plate 4 is provided with a large number of circular holes 4a to reduce ventilation resistance.
- the patterns shown in FIGS. 5 and 6 are printed on both sides.
- the surface with the "bear" pattern shown in Fig. 5 can be seen, while when installed in a bedroom, the muted color pattern in Fig. 6 can be seen. It makes the printed surface visible.
- Fig. 4 shows a cross-sectional view taken along the line IV-IV in Fig. 2 (A).
- the turbo fan 11 blows air sucked from the front in the axial direction and radially outwards with respect to the shaft.
- the heat exchanger 12 is arranged in the casing 1 so as to satisfy the condition described above, and is disposed axially forward of the turbo fan 11.
- the air conditioner indoor unit draws air from the front through the mesh-shaped flat plate 4, the filter 3, and the heat exchanger 12 when the tap fan 11 rotates.
- the blown air is blown radially outward from the axis of the turbo fan 11 in four directions (up, down, left and right) from the outlet 1a.
- one of the front and rear surfaces of the mesh flat plate 4 is selected, and the selected flat surface is directed forward, and the mesh flat plate 4 is attached to the inlet 2 a of the front panel 2.
- mesh-shaped flat plate 4 If the above-mentioned mesh-shaped flat plate 4 is to be mounted upside down, after removing the mounting frame 5, the picture on the back side of the mesh-shaped flat plate 4 is turned to the front side, and the mesh-shaped flat plate 4 is again mounted on the front panel 2 by the mounting frame 5. Attached to the suction port 2a.
- a mesh-shaped flat plate having a different pattern or color may be provided separately, and the pattern or color of the mesh-shaped flat plate may be selected according to the interior of the room or according to the taste and season of the resident.
- the air conditioner indoor unit that can respond to various demands at low cost.
- the c can be realized, the meshed flat plate 4 can be easily performed wiping dirt compared to large suction grille of a conventional unevenness.
- a pattern can be easily printed on the plane portion of the mesh-shaped flat plate 4, so that indoor units of various patterns and colors can be manufactured at low cost.
- the mesh-shaped flat plate 4 is made detachable, by separately preparing mesh-shaped flat plates having different patterns and colors, the range of design choices can be expanded and the degree of freedom can be increased.
- mesh-shaped flat plate 4 can be attached with both the front and rear faces facing forward, there is no need to separately prepare mesh-shaped flat plates with different patterns and colors. Can be selected.
- the mesh flat plate 4 has a structure that can be mounted with one of the surfaces facing forward, that is, a structure in which the mesh flat plate 4 can be installed upside down.
- the one with the attached structure may be used.
- the mesh flat plate 4 is mounted on the suction port 2a of the front panel 2 together with the filter 3 by the mounting frame 5, but the mounting structure of the mesh flat plate is not limited to this.
- the indoor unit of the air conditioner of the present invention has various external needs, for example, T JP98 / 04451
