BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust remover for an air filter for an air conditioner, and more particularly, to automatically remove dust adhering to the air filter to minimize overheating and heat loss of the air conditioner. The present invention relates to a dust removing device for an air filter for an air conditioner that can increase the heating effect and prevent indoor air pollution.

[0002]

2. Description of the Related Art Conventionally, as such an air filter for an air conditioner, one described in Japanese Patent Laid-Open No. 3-137950 has been known. According to the above publication, as shown in FIG. 4, it comprises a rear cover 1, a frame 2, a front cover 3, an indoor air inlet 4, a free filter 5, a filter case 6, a counter electrode plate 7 and a discharge wire 8. There is.

A centrifugal fan 9 and a motor 10 for rotating the fan are built in the rear cover 1.
As the fan 9 rotates, a high voltage is applied and the discharge line 8
A corona discharge is generated between the counter electrode plate 7 and the counter electrode plate 7 to charge dust, and the dust is collected by the dielectric filter 11a and the removal filter 11b installed in the filter case 6 on the rear side, and air is conditioned. Is circulated through the air outlet 12 into the room to keep the indoor air comfortable.

However, in the electrostatic precipitator having the above structure, there is a problem that the filter case 6 must be periodically removed from the main body to clean the filter.

Further, in the conventional air conditioner, FIG.
Further, as shown in FIG. 6, a front panel 5 is provided on the front surface of the air conditioner body 1. A discharge grille member 3 having a wind improvement lower adjusting plate 3a and a wind direction left / right adjusting plate 3b is arranged on an upper portion of the front panel, and foreign matters such as dust contained in the sucked indoor air are arranged on a lower portion of the front panel. A suction grille member 4 having an air filter 4a therein is disposed for clean filtering. A driving operation unit 2 for controlling the air conditioner is arranged on the upper right side of the front panel 5 between the suction grill member 4 and the discharge grill member 3.

Here, the air filter 4a has substantially the same size as the inner surface of the suction grill member 4,
It can be removed and assembled to remove dust and the like while being in close contact.

[0007]

By the way, in the conventional air conditioner air filter 4a having the above-mentioned structure, if the air conditioner is used for a long time, dust and the like contained in the air in the room will be sucked. It adheres to the air filter through the grill member and reduces the heating effect. Therefore, in order to prevent this, the dust must be removed at least once a month.

That is, the air conditioner in operation is stopped (about 2
6 to 15 minutes), as shown in FIG. 6, the suction grill member is pulled out from the air conditioner main body and the air filter 4a is removed upward so that the user can remove the air filter 4a.
There is an inconvenience and annoyance that the dust adhering to must be washed with water or the dust must be removed using an electric vacuum cleaner or the like.

Furthermore, if dust is not removed regularly, a decrease in air volume causes overheating of a motor (not shown) that drives peripheral equipment in the air conditioner and a convection blower (not shown), causing a fire. In addition, since the convection blower has to be driven at a high rotation speed due to low circulation efficiency of indoor air, a large amount of heat loss is caused and the heating effect is reduced. .

Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to provide an air filter member by rotating an endless belt type air filter member by an air filter driving means. An object of the present invention is to provide a dust removing device for an air filter for an air conditioner, which removes dust attached by applying vibration.

[0011]

In order to achieve the above object, a dust removing device for an air filter of an air conditioner according to the present invention is provided with an indoor air intake port provided at a lower portion of an air conditioner body. By filtering the suction grill member provided on the front side and the convection blower arranged at the lower part of the air conditioner body, dust contained in the room air sucked through the suction grill member is filtered. An air filter member, an air filter driving unit that rotates the air filter member to remove dust adsorbed on the air filter member, and a dust dropped from the air filter member by driving the air filter driving unit. It is characterized by comprising a dust suction means for sucking into the combustion chamber.

In the present invention constructed as described above, the belt type air filter member is rotated by the air filter driving means to apply vibration to the air filter member to separate the dust adhering to the air filter member and to separate the dust. By driving the fan in the burner section, the waste is supplied to the combustion chamber through the suction hose, mixed with the combustion fuel and burned, and the combustion gas is exhausted to the outside through the chimney section. Therefore, it is possible to eliminate the inconvenience and annoyance that the user has to manually wash the dust attached to the air filter as in the past, or to remove the dust attached to the air filter with a vacuum cleaner. it can.

Furthermore, since the dust adhering to the air filter member is driven through the dust suction hose periodically by driving the fan of the burner section, the air filter member is always kept clean. In addition, there is no fear that the amount of air sucked from the outside will decrease, and the risk of an accident such as a fire due to overheating of peripheral devices and the motor of the convection blower can be eliminated. Also,
The heat rate and heating effect can be increased.
