DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter dust removing device for an air conditioner, which is provided for cleaning a filter for collecting dust.

[0002]

2. Description of the Related Art Conventionally, air conditioners have been provided with a detachable filter for the purpose of collecting dust to prevent dust and dirt from being clogged in a ventilation circuit of the equipment and deteriorating performance.
The filter was removed regularly and washed with water and vacuumed to remove dust and dirt.

[0003]

However, in the above-described conventional configuration, when the filter is mounted at a high place, dust or the like may fall on the face or body when the filter is removed.
Hands were dirty and unsanitary. Therefore, Japanese Patent Laid-Open No. 7-8
As described in Japanese Patent No. 8313, a method of automatically washing with water without removing a filter has been devised, but in this case, it is necessary to always fill the water tank with water and it is troublesome. In addition, there is a problem that the water may become contaminated if it becomes dirty, and there is a possibility that water may leak.

The present invention has been made to solve such a conventional problem, and provides a filter dust removing apparatus for an air conditioner which can clean a filter without removing the filter and can always operate in a clean state. The purpose is to:

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a dust removing device for an air conditioner filter having a mechanism for scraping off dirt and dust accumulated on the filter with a brush. No human cleaning is required. Therefore, when removing the filter, dust and dirt do not fall on the face or body, hands become dirty and unsanitary, and because it does not use water, there is no need to replenish water, and the floor will leak due to water leakage. Don't worry about getting dirty.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Claim 1 for solving the above problem.
In the invention described in (1), a brush that moves up and down is installed on the front surface of the filter. And according to this configuration,
When dust and dirt accumulate on the surface of the filter, move the brush from top to bottom to remove and collect dirt and dust.The removed and collected dust and dirt fall into the condensed water tray of the heat exchanger, Dust is discharged outside by the condensed water in the heat exchanger.

Further, the brush is moved under the filter, and a comb is used to completely remove dust and dirt adhering to the brush when returning to the upper position.

According to a second aspect of the present invention, when the brush moves downward while collecting dust and dirt, the brush is attached at an acute angle to the moving direction in order to improve the efficiency of collecting dust and dirt. ing.

According to a third aspect of the present invention, a dedicated collection box that can be attached and detached is installed below the filter without removing the dust and dust removed and collected by the moving brush onto the condensed water receiving tray of the heat exchanger. It was done. And according to this configuration, the dirt and dust removed by the brush can be collected in one place,
Once collected, they can be discarded together.

According to a fourth aspect of the present invention, the brush is rotated to improve the performance of removing dirt and dust deposited on the filter, and the rotating direction of the brush at this time is opposite to the traveling direction. By rotating in the direction, the efficiency of removing dirt and dust is improved.

In addition, when the rotating brush moves to the bottom of the filter and then moves upward, the rotating brush is reversely rotated so that dust and dirt attached to the brush can be efficiently removed with a comb.

According to a fifth aspect of the present invention, by fixing the brush and moving the filter, the thickness of the air conditioner main body in the front-rear direction (depth) is reduced to save space.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) In FIG. 1, 1a is a dust collecting device, 2a is a brush, 3 is a drive motor, 4 is a rail, and 5 is a comb.

FIG. 2 is a cross-sectional view when the dust collector 1a is installed along the front surface of the filter 6 installed in the air conditioner. The brush 2a is positioned above the dust collector 1a in the initial state. are doing.

In the above configuration, when dust and dust accumulate on the filter 6, the brush 2a of the dust collector 1a is moved along the rail 4 by the drive motor 3 to scrape the dust and dust accumulated on the filter 6. After moving to the lower side, it moves to the upper fixed position.

At this time, in order to prevent the dirt and dust collected by the brush from becoming entangled with the brush, the comb 5 is tilted downward below the rail 4 so that the brush returns to a fixed position. The comb 5 can remove dirt and dust attached to the brush.

(Embodiment 2) In FIG. 3, the brush 2b
It is mounted so that it is at an acute angle to the downward movement direction. As a result, the brush 2b has an effect of scraping dirt and dust on the surface of the filter 6, so that when it moves downward, the efficiency of collecting dirt and dust can be improved.

(Embodiment 3) In FIG. 4, reference numeral 7 denotes a detachable refuse collection box for collecting refuse and dust collected by a brush, and is a cross-sectional view when the refuse collection box is installed below the dust collector 1 and the filter 6. .

According to this embodiment, dirt and dust removed by the brush can be collected in one place, accumulated and discarded collectively, and cleaning can be easily performed and a clean state can be maintained.

(Embodiment 4) FIG. 5 shows a dust collector 1 constituted by a rotary brush 2c.

The rotating brush 2c has an effect of hitting the filter 6 and can further improve the dust collection efficiency of dust and dirt.

(Embodiment 5) FIG. 6 shows a configuration in which a take-up device 9 for the movable filter 8 is attached to an end face of the movable filter 8, and the movable filter 8 is slid up and down.

FIG. 7 shows a dust collector 1b, in which a fixed brush 10 is fixed to a guide 11, and a movable filter 8 is provided.
The dust is slid by the winding device 9 so that dirt and dust are scraped off by the fixed brush 10. According to this configuration, the rail 4 of the dust collector 1 is eliminated, and the thickness (depth) before and after the air conditioner can be reduced, so that the weight and space can be reduced.

[0025]

As is apparent from the above embodiment, the first aspect of the present invention is such that a brush that moves up and down is installed on the front surface of the filter. According to this configuration, when dust and dust accumulate on the filter surface, the brush can be moved up and down to remove the dust and dust.

According to a second aspect of the present invention, the efficiency of collecting dust and dirt is improved by mounting the brush at an acute angle with respect to the moving direction.

According to a third aspect of the present invention, a collection box is provided below the dust removing device. According to this configuration, the dirt and dust removed by the brush can be collected in one place, accumulated and discarded collectively, and the inside of the collection box can be easily cleaned.

According to a fourth aspect of the present invention, the performance of removing dirt and dust on the filter surface is improved by rotating the brush.

According to a fifth aspect of the present invention, the thickness (depth) in the front-rear direction is reduced by fixing the brush and operating the filter to reduce the weight and space.
