Filter structure capable of removing dust

Abstract

A filter structure capable of removing dust is proposed. The filter structure includes a circular rim part; a frame, extending from the rim part, for installing a motor; a dust collection net attached to the frame; a brush which is in close contact with the dust collection net and is rotated by the motor; an opening, formed at a lower end of the rim part, for discharging dust; an open part formed at one side of the dust collection net; and a concave groove part having an outside coupled to the open part and in one-side communication with the opening at the rim part.

Claims

1. A filter structure capable of removing dust, comprising a circular rim part, frames configured to extend from the circular rim part so as to install a motor thereon, a dust collection net attached to the frames, a brush configured to be in close contact with the dust collection net and to be rotated by the motor, and an opening formed at a lower end of the circular rim part so as to discharge dust therethrough, wherein: an open part is formed at one side of the dust collection net; a concave groove part, which communicates with the opening formed at the lower end of the circular rim part, is formed on one of the frames; and the concave groove part penetrates the dust collection net through the open part of the dust collection net so that dust swept by the brush is naturally discharged to the opening through the concave groove part.

2. The filter structure according to claim 1, wherein an upper end of the concave groove part is located under a motor shaft, and a lower end of the concave groove part is located over the opening.

BEST MODE

(6) Hereinafter, reference will be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. However, the disclosure of the invention is not limited to the embodiments set forth herein and may be variously modified. The terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to limit the present invention. Further, as used herein, the singular forms may be intended to include the plural forms as well, unless the context clearly indicates otherwise. In the following description of the embodiments, terms, such as “comprising”, are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. All terms including technical terms and scientific terms used herein have the same meanings as those understood by those skilled in the art, unless stated otherwise. Terms defined in dictionaries which are usually used are to be interpreted as having meanings coinciding with relevant technical documents and the present disclosure, and are not to be interpreted as having ideal or formal meanings, unless defined otherwise.

(7) The embodiment of the present invention, which will be described with reference to perspective views, specifically indicate the ideal embodiment of the invention. Consequently, various modifications to what is illustrated, for example, modifications of manufacturing methods and/or specifications, can be expected. Therefore, the embodiments are not limited to the specific forms in the regions shown, and, for example, may include modifications of forms due to manufacture. For example, a region illustrated or described as being even may have a rough or rough and nonlinear property. Further, a part illustrated as having a sharp angle may be rounded. Therefore, the regions shown in the drawings are merely approximate, and the forms thereof are not intended to illustrate the correct forms of the regions, and are not intended to limit the scope of the invention.

MODE FOR INVENTION

(8) Hereinafter, an exemplary embodiment of a dust collector for air conditioners according to the present invention will be described in detail with reference to the accompanying drawings.

(9) FIG. 1 is an exploded perspective view of the dust collector for air conditioners according to the present invention, FIG. 2 is a perspective view illustrating the dust collector of FIG. 1 in an assembled state, FIG. 3 is a cross-sectional view of FIG. 2, FIG. 4 is a reference view illustrating the usage state of the dust collector according to the present invention, and FIG. 5 is a cross-sectional view illustrating the usage state of the dust collector according to the present invention.

(10) First, in the drawings, the same or similar elements are denoted by the same reference numerals even when they are depicted in different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

(11) A dust collector 100 for air conditioners according to one embodiment of the present invention includes a circular rim part 110, frames 130 configured to extend from the rim part 110 so as to install a motor 160 thereon, a dust collection net 120 attached to the frames 130, a brush 170 configured to be in close contact with the dust collection net 120 and to be rotated by the motor 160, an opening 140 formed at the lower end of the rim part 110 so as to discharge dust therethrough, an open part 121 formed at one side of the dust collection net 120, and a concave groove part 131 having the outside coupled to the open part 121 and one side communicating with the opening 140 of the rim part 110.

(12) Here, the shape of the dust collection net 120 in the present invention may be a disc shape, and the reason for this is that the brush 170 must be rotated by the motor 160 so as to wipe off dust from one side surface of the dust collection net 120.

(13) The upper end of the concave groove part 131 may be located under a motor shaft 161, and the lower end thereof may be located over the opening 140. The reason for this is that, when the brush 170 is rotated, the brush 170 in an upright state may be most capable of easily wiping off dust.

(14) A plurality of frames 130 extends from the rim part 110, and is necessary to allow the motor 160 to be stably coupled thereto and to support the dust collection net 120.

(15) A through hole 131a, through which the motor shaft 161 passes, is formed through the center among the frames 130.

(16) The motor shaft 161 passing through the through hole 131a passes through the center of the dust collection net 120, and is coupled to the brush 170 rotated in the state in which the brush 170 is in close contact with the dust collection net 120.

(17) A dust removal unit, which may remove dust from one side surface of the dust collection net 120 without damaging the dust collection net 120, may be formed at one end of the brush 170, and the dust removal unit may be formed of mohair, a soft resin plate, a rubber plate, or the like.

(18) A coupling unit which couples the dust collector to one side of an external air inlet of an air conditioner (not shown) may be provided at the rim part 110, and when a screw is used as the coupling unit provided at the rim part 110, a screw hole, into which the screw is inserted may be formed, when a circular connector protrudes from the inside of the external air inlet, the rim part 110 may be coupled to the connector by interference fit, or the rim part 110 may be coupled to the external air inlet by engagement using known coupling and latch units, or the rim part 110 may be coupled to the external air inlet by screw combination using spiral threads formed therein. In addition, it is apparent that various other well-known coupling units may be used.

(19) The concave groove part 131 coupled to the open part 121 of the dust collection net 120 serves to facilitate discharge of dust when the dust filtered out on one surface of the dust collection net 120 is swept by the brush 170, and a dust outlet 150 may be formed at the lower end of the opening 140 so as to discharge the collected dust to the outside of the air conditioner via a dust discharge pipe A.

(20) Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
