Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an air conditioner provided with a filter device capable of automatic cleaning.
[0002]
[Prior art]
In the conventional air conditioner, as shown in FIGS. 8 and 9, an air filter 6 for preventing dust from entering the inside of the main body of the air conditioner is provided on the front surface of the heat exchanger 11. The air filter 6 is detachably configured so that the attached dust can be cleaned by hand.
[0003]
On the other hand, an air conditioner is known in which a rotating brush, a brush cover, and a filter brush composed of a pinion provided coaxially with the rotating brush are configured as cleaning means for an air filter (for example, see Japanese Patent Application Laid-Open No. H11-163873). Reference 1).
[0004]
Further, there is known a trapping device, a cleaning device, a suction mechanism, a carrier beam connected to the suction mechanism, a hose connected to the carrier beam, a vacuum generator, and the like (for example, a known device). Patent Document 2).
[0005]
Further, a drive shaft and a driven shaft having a belt-shaped filter stretched thereon, a servomotor, a brush, a dust sensor and a fan disposed in an exhaust pipe, and arithmetic processing means for calculating a continuous use time of the filter. And a control means are known (for example, see Patent Document 3).

[Problems to be solved by the invention]
However, the above-described conventional filter configuration requires periodic maintenance such as removing the air conditioner from the air conditioner in accordance with the frequency of use of the air conditioner, and washing the attached dust with water or a vacuum cleaner. In addition, when the periodic maintenance is not performed, dust accumulates on the air filter, and the ventilation resistance of the intake air increases, so that the performance of the air conditioner decreases and the power consumption increases.
[0008]
In addition, there are restrictions on the operation means, and the time and effort for dust treatment after dust collection are increased, so that the method is not reliable.
[0009]
In addition, there are problems such as limitations on the operation means and an increase in the size of the main body.
[0010]
[Means for Solving the Problems]
In order to solve the conventional problem, the air conditioner of the present invention includes a filter frame, an air filter, a plurality of movable suction nozzles, and a suction duct provided in the plurality of suction nozzles. It is provided with a filter device having a suction and exhaust device and an exhaust duct to be connected.
[0011]
With the above configuration, the air filter can be automatically and reliably cleaned, so that the performance of the air conditioner can be maintained and the power consumption can be prevented from increasing.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0013]
(Embodiment 1)
1 is a perspective view of a filter device according to Embodiment 1 of the present invention, FIGS. 2 and 3 are external views of a suction nozzle according to Embodiment 1 of the present invention, FIG. 4 is a front view of an air conditioner, FIG. FIG. 6 is a cross-sectional view of the air conditioner according to Embodiment 1 of the present invention.
[0014]
A heat exchanger 11 and a fan 12 are provided inside the air conditioner main body 13, and the operation of the fan is performed through a plurality of suction ports (not shown) formed from the front surface to the upper surface of the main body 13. And the dust floating in the air is removed by the filter device 1 provided between the suction port and the heat exchanger 11.
[0015]
The filter device 1 includes a filter frame 2, an air filter 6, a movable suction nozzle 5, a suction duct 3 provided on the suction nozzle 5, and a suction and exhaust device 7 and an exhaust duct 8 connected to the suction duct 3. It consists of. Here, two suction nozzles 5 are arranged in a form arranged side by side in the moving direction of the suction nozzles 5, and each has a first suction port 5 a 1 and a second suction port 5 a 2. The first suction port 5a1 opens at a position facing the front surface of the air filter 6, and the second suction port 5a2 opens at a position facing the upper surface of the air filter 6.
[0016]
The operation of the filter device 1 configured as described above will be described. After the operation of the air conditioner main body 13 is stopped, the suction / exhaust device 7 starts operating, and air flows from the first suction port 5a1 and the second suction port 5a2 respectively provided to the two suction nozzles 5 installed in the suction duct 3. Start sucking. Then, the two suction nozzles 5 located at one end of the air filter 6 are moved in the direction of arrow A as shown in FIG. The dust adhering to the surface of the suction nozzle 6 is sucked from the first suction port 5a1 and the second suction port 5a2 provided in the suction nozzle 5, and the dust passes through the suction duct 3 and the suction / exhaust device 7, and is discharged from the exhaust duct 8 to the outside of the room.
[0017]
Here, if the drive motor 10 is rotated reversely when the suction nozzle 5 cleans the entire surface of the air filter 6 and moves to the opposite one end, the suction nozzle 5 moves in the direction to return to the initial position. Thus, the surface of the air filter 5 can be cleaned again.
[0018]
As described above, by providing the two suction nozzles 5 and dividing the suction port, the opening area of the suction port per suction nozzle can be reduced, so that the speed of the suction air passing through the suction port can be reduced. And the suction force can be increased. For this reason, the dust adhering to the surface of the air filter 6 can be more reliably sucked.
[0019]
In the present embodiment, two suction nozzles 5 are provided, but in some cases, two or more suction nozzles may be provided. Further, as shown in FIGS. 2 and 3, in one suction nozzle 5, the suction passage 5c may be divided, and a suction port may be provided in each suction passage 5c.
[0020]
According to this embodiment, an air conditioner can be provided with a filter device that is excellent in dust-absorbing performance and that can be automatically cleaned, so that performance can be maintained and power consumption can be prevented from increasing.
[0021]
(Embodiment 2)
FIG. 7 is a view for explaining Embodiment 2 of the present invention.
[0022]
By arranging the suction ports 5a1 and 5a2 individually provided in the divided suction passages 5c in a direction perpendicular to the moving direction of the suction nozzle 5 without a gap or overlapping (δ ≧ 0), air The suction can be performed without leaving the dust attached to the surface of the filter 6. Therefore, the air filter 6 can be more reliably cleaned.
[0023]
【The invention's effect】
As described above, in the air conditioner of the present invention, a filter frame, an air filter, a plurality of movable suction nozzles, a suction duct provided for the plurality of suction nozzles, and a suction duct connected to the suction duct are further provided. By providing a filter device including an exhaust device and an exhaust duct, it is possible to automatically and reliably clean the air filter, thereby maintaining the performance of the air conditioner and preventing an increase in power consumption. This has the effect that it can be achieved.
