- 'Patent Document 2 Japanese Patent Application Laid-Open No. 6- 7 4 5 2 1
- the present invention is an air conditioner having an indoor unit in which a heat exchange and a blower are stored in a housing, and the suction port formed in the housing and the heat exchange ⁇ ⁇ A rotatable disk-like air filter provided between the air filter, an air filter driving means for rotationally driving the air filter, and a suction nozzle for suctioning dust attached to the air filter against the air filter. And an attached suction unit.
- the room air can be kept clean at all times. .
- the air filter has a rack formed on the outer periphery thereof, and the drive means of the air filter has a gear that meshes with the rack, and rotating the gear causes the air filter to rotate through the rack. Then, the rotation mechanism of the air filter can be configured simply and compactly.
- the suction nozzle is attached to the suction unit so that it can swing freely and the suction operation of the suction unit is stopped, if the suction nozzle is moved out of the projection surface of the air filter, the suction nozzle resists the air drawn into the indoor unit. Heat exchange efficiency is improved.
- the shielding plate facing the suction nozzle on the opposite side of the suction nozzle with the air filter in between, the inflow path of the air sucked into the suction nozzle can be limited, and the dust collection efficiency can be improved.
- the shielding plate and the suction nozzle are integrally formed, the shielding plate can be shaken with the suction nozzle with a simple configuration. If the area of the shielding plate facing the air filter is set equal to or larger than the opening area of the suction nozzle, it is preferable from the viewpoint of improving the dust collection efficiency.
- the proximal end of the suction nozzle may be disposed substantially at the center of the air filter, and the length of the suction nozzle may be set approximately equal to the radius of the air filter.
- the air filter can be cleaned automatically by the above-mentioned configuration, when the air filter is detachably attached to the housing, if the air filter becomes contaminated with oil, the air filter should be removed from the housing and cleaned. Can.
- FIG. 1 is a cross-sectional view of an indoor unit of an air conditioner according to the present invention.
- FIG. 2 is an enlarged view of part I of FIG.
- FIG. 3 is an enlarged view of a part of FIG.
- FIG. 4 is an enlarged view of a portion III of FIG.
- FIG. 5 is a perspective view of a suction nozzle provided in the indoor unit of FIG.
- FIG. 6 is a perspective view of an air guider provided in the indoor unit of FIG.
- FIG. 7 is a bottom view of the suction nozzle and the air filter.
- FIG. 8 is a cross-sectional view of a suction gap.
- FIG. 9 is a cross-sectional view of the interior of a conventional air conditioner.
- FIG. 1 is a cross-sectional view of an indoor unit of a ceiling-embedded air conditioner according to the present invention
- FIGS. 2, 3 and 4 are enlarged views of I, ⁇ and ⁇ in FIG. 1, respectively.
- Fig. 5 is a perspective view of the suction nozzle
- Fig. 6 is a perspective view of the air guider
- Fig. 7 is a view from below of the air filter and suction unit.
- the indoor air is supplied to the suction grille 6 provided on the front grille 1 by the fan 10 disposed inside the body casing 8 and driven by the drive motor 11;
- the air passes through the air filter 5 and the air guider 4 and is exchanged by heat exchange and blown out to the outlet 19. During this time, dust mixed in the air adheres to the air filter 5 and does not adhere to the inside of the indoor unit.
- a net 5c is stretched on the front surface of a disk-like frame, a rack 5a is formed on the outer periphery of the frame, and the air filter 5 rotates at the center. Center of rotation and attach to the air guider 4 It has a mounting hole 5 b for rotation, and is rotatably mounted to an air filter support shaft 4 a (FIG. 3) formed in the air guider 4 by means of a screw 16.
- the motor 15 is disposed in the air guider 4 and has a gear wheel 14, and when the motor 15 is driven, the air filter 4 is engaged with the air filter 5 via the rack 5 a of the air filter 5. 5 turns ( Figure 4).
- the suction nozzle 12 has a suction portion 12a and an opening portion 12b, and is pivotable to the suction unit 13 by fixed shafts 12c and 12d so as to face the front side of the air filter 5. It is fitted.
- the suction portion 12 a has a length substantially equal to the radius of the air filter 5, the base end thereof is positioned substantially at the center of the air filter 5, and the tip end thereof is positioned at the outer periphery of the air filter 5.
- the suction unit 13 is equipped with a fan for suction and a unit (not shown) for collecting suctioned dust.
- a fan for suction By operating the suction fan, the dust attached to the air filter 5 is suctioned by the suction nozzle 1 It is sucked by the suction part 1 2 a of 2 and passes through the opening part 1 2 b to reach the collection unit.
- the suction nozzle 12 can freely swing with the fixed shafts 12c and 12d as swing shafts, and the motor 17 and the fixed shaft 12c are joints 1 8 Connected to each other.
- the suction nozzle 12 moves to the front of the air filter 5 by the operation of the motor 17 when performing suction operation, and moves to a position where it does not overlap with the air filter 5 when there is no need for suction operation. It prevents the resistance of the air being inhaled more.
- a shielding plate 4b having an area substantially equal to that of the suction portion 12a of the suction nozzle 12 is provided at a position opposite to the air filter 5 with the air filter 5 interposed therebetween.
- the shielding plate 4 b restricts the inflow path of the air sucked into the suction nozzle 12, and improves the efficiency of collecting dust attached to the air filter 5.
- FIG. 8 shows another embodiment of the shielding plate, in which the shielding plate 12 e has an area substantially equal to that of the suction port 12 a of the suction nozzle 12, and is positioned opposite to the air filter 5.
- the suction nozzle 12 is integrally formed.
- the shielding plate 12 in this embodiment is a suction nozzle 1 when the suction operation is stopped.
- the air filter 5 can also be removed by removing the screw 16 so that it can be removed and cleaned if oil that can not be removed by the suction device is attached. Also, as an alternative to the screw 16, it is possible to make the mounting hole 5b of the air filter 5 or the support shaft 4a of the air guider 4 flexible to facilitate the attachment and detachment.
- the collection unit for collecting the dust sucked by the suction nozzle 12 is provided in the suction sheet 13, the opening of the suction nozzle 12 is not provided with the collection unit.
- a flexible hose may be connected to 12 b and dust sucked by the suction nozzle 12 may be discharged to the outside through the flexible hose.
