Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a filter device for an air conditioner that automatically cleans a filter.
[0002]
[Prior art]
As shown in FIG. 6, the conventional air conditioner filter device is provided with an air filter 5 on the front surface of the heat exchanger 10 for preventing dust from entering the inside of the main body of the air conditioner. The air filter 5 is configured to be detachable so that attached dust can be cleaned by hand.
[0003]
On the other hand, as an air conditioner that can easily clean an air filter, there is an air filter cleaning unit that includes a rotating brush, a brush cover, and a filter brush that is formed coaxially with the rotating brush. (For example, refer to Patent Document 1).
[0004]
In addition, there is a configuration that includes a collection 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, Patent Documents). 2).
[0005]
A driving shaft and a driven shaft on which a belt-like filter is stretched, a servo motor, a brush, a dust sensor and a fan disposed in the exhaust pipe, and an arithmetic processing means for calculating a continuous use time of the filter; The control means is configured (see, for example, Patent Document 3).

[Problems to be solved by the invention]
However, the configuration of the conventional filter requires periodic maintenance that is removed from the air conditioner according to the frequency of use of the air conditioner and cleaned of dust adhering with water or a vacuum cleaner. In addition, when periodic maintenance is not performed, there is a problem that dust is accumulated on the air filter and the ventilation resistance of the intake air is increased, so that the performance of the air conditioner is reduced and the power consumption is increased.
[0008]
In addition, there are restrictions on the operation means, and it is not a reliable means because dust processing after dust collection is required. In addition, the main body size has been increased.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, a filter device of the present invention is provided with a filter frame, an air filter, and a movable suction nozzle, a suction duct is provided in the suction nozzle, and a plurality of suction ports are provided in the suction nozzle. provided side by side in staggered two rows along the longitudinal direction of the suction nozzle, the length of the inlet with respect to the longitudinal direction of the suction nozzle is set to be larger toward the upper direction or the rear direction, the suction A brush is provided between the one row of the mouths and the other row along the row of the suction ports, and when moving the suction nozzle in a direction perpendicular to the longitudinal direction of the suction nozzle, the one row The suction area of the suction port and the suction area of the suction port of the other row are configured not to overlap each other .
[0010]
With the above configuration, the air filter can be automatically cleaned, and the performance of the air conditioner can be maintained and the increase in power consumption can be prevented. In addition, dust can be uniformly absorbed from the front of the nozzle to the back.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0012]
1 is a perspective view of a filter device according to an embodiment of the present invention, FIG. 2 is an external view of a suction nozzle of the filter device according to an embodiment of the present invention, and FIG. 3 is a front view of an indoor unit according to the embodiment of the present invention. 4 and 5 are sectional views of the air conditioner according to the embodiment of the present invention.
[0013]
A heat exchanger 10 and a fan (not shown) are disposed inside the air conditioner main body 11, and from a plurality of suction ports (not shown) formed from the front surface to the upper surface of the main body 11. The air is sucked in by the operation of the fan, and the dust floating in the air is removed by the filter device 1 provided between the suction port and the heat exchanger 10.
[0014]
This filter device 1 is provided with a filter frame 2, an air filter 5, and a movable suction nozzle 4, a suction duct 3 is provided in the suction nozzle 4, and a suction exhaust device 6 connected to the suction duct 3 and an exhaust gas. In the air conditioner equipped with the duct 7, a plurality of variable suction ports 4 a are provided in a staggered manner in the suction nozzle 4, and the length dimension B of the plurality of variable suction ports 4 a goes in the upward direction and the back direction. It is set to become larger according to. Further, a brush 4b adjacent to the suction port 4a is provided.
[0015]
The operation of the filter device 1 configured as described above will be described. After the operation of the air conditioner main body 11 is stopped, the suction / exhaust device 6 starts to operate and starts to suck air from the suction port 4 a of the suction nozzle 4 installed in the suction duct 3. Then, the suction nozzle 4 located at one end of the air filter 5 is moved in the direction of arrow A by the drive wire 8 connected to the drive motor 9, and the brush 4 b of the suction nozzle 4 is attached to the surface of the air filter 5. The dust is sucked out from the plurality of variable suction ports 4a of the suction nozzle 4 while scraping the dust, and the dust passes through the suction duct 3 and the suction exhaust device 6 and is discharged from the exhaust duct 7 to the outside.
[0016]
Here, when the suction nozzle 4 cleans the entire surface of the air filter 5 and moves to the opposite one end, if the drive motor 9 is rotated in the reverse direction, the suction nozzle 4 moves in a direction to return to the initial position. It becomes possible to clean the surface of the air filter 5 once again.
[0017]
According to this embodiment, dust can be uniformly absorbed from the front side to the back side of the suction nozzle 4 without any unevenness.
[0018]
【The invention's effect】
As is apparent from the above, the present invention provides a filter frame, an air filter, a movable suction nozzle in the filter device, a suction duct in the suction nozzle, and a suction exhaust device connected to the suction duct. In the air conditioner having an exhaust duct, a plurality of variable suction ports are provided in a staggered manner in the suction nozzle, and a brush adjacent to the suction port is further provided. According to this configuration, there is an effect that dust can be uniformly and uniformly absorbed from the front of the nozzle to the back.
