Description

Filter structure capable of removing dust

[0001] The present invention relates to a filter structure capable of removing dust, and more specifically, to a filter structure that effectively discharges dust collected by a filter installed in an air conditioner or the like to the outdoors, thereby minimizing the need for periodic cleaning or replacement of the filter.

[0002] In general, due to recent environmental pollution, which has led to a lot of dust floating in the air, and also due to the growing concern for health, filters are being used in various air conditioning systems to remove dust contained in the air flowing into or out of buildings.

[0003] The above air conditioning device is intended to forcibly suck in or exhaust indoor air or outdoor air through a ventilation fan, but the filters used in the above air conditioning device, especially the filters used in air conditioning devices that exhaust indoor air to the outside, are not functioning properly due to users' indifference and difficulty in replacing the filters.

[0004] In other words, when a lot of dust accumulates in the filter, it needs to be cleaned or replaced. However, if left for a long time, the air flow will become worse, which increases the risk of the ventilation fan's function deteriorating and the motor breaking down.

[0005] Additionally, dust that is inhaled indoors and is not discharged through the filter has a high possibility of being re-introduced into the room, which can cause deterioration of indoor air quality and threaten the health of indoor residents.

[0006] Of course, in order to solve the above problem, the inventor of the present invention has previously applied for a dust removal filter structure including a circular frame as shown in FIG. 1, a frame extending from the frame to support a dust collecting net, a dust collecting net attached to the frame, a brush that is in close contact with the dust collecting net and rotates by a motor, an opening formed at the lower end of the frame to discharge dust, a through hole formed on one side of the dust collecting net, and a concave groove having an outer side joined to the through hole and one side communicating with the opening of the frame, as previously filed as Republic of Korea Patent Registration No. 10-1946255.

[0007] However, this is not a structure that discharges dust from indoors to outdoors, but rather a structure that processes dust indoors, so it has the disadvantage of requiring the user's effort to remove the dust.

[0008] Therefore, the need for a filter is greater than ever, as the filter structure capable of removing dust, as described in Korean Patent Registration No. 10-1946255, has been improved so that users do not have to clean or replace the filter.

[0010] [Prior Art Literature]

[0011] 1. Republic of Korea Patent Registration No. 10-1946255

[0012] The purpose of the present invention to solve the above-mentioned problem is to have a brush that is attached to the dust collecting net of a filter and rotates in close contact with the dust collecting net to sweep away the accumulated dust, and to enable the dust brushed away by the brush to be discharged from the inside to the outside by the blower fan of the air conditioning device through an opening, a damper, and a damper opening / closing means, thereby eliminating the need for the user to clean or replace the filter.

[0013] Looking at a solution according to an embodiment of the present invention for achieving the above-described purpose, it is characterized by comprising a frame for supporting a dust collecting net, a dust collecting net attached to the frame except for an opening, a brush that is rotated by a motor so as to be in close contact with the dust collecting net and shake off dust, an opening formed in the frame so as to coincide with an opening of the dust collecting net, a damper formed in the opening so as to be opened and closed by its own weight or the elasticity of a spring, and a damper opening / closing means formed in the brush and for pushing and opening the damper.

[0014] In another embodiment of the present invention, the damper is characterized in that it is rotatable and comprises an opening plate for blocking an opening and an axis formed on one or both sides of the opening plate.

[0015] In another embodiment of the present invention, the damper opening / closing means is characterized by being configured as a push rod installed on the brush head or one side of the brush to push and open the damper.

[0016] In another embodiment of the present invention, the pressing member is characterized in that it is configured to have a spring so as to push the damper by elasticity.

[0017] The above-described effect of the present invention is that dust accumulated on the dust collecting net of the filter is swept away by a brush that is in close contact with the dust collecting net and rotates, and the dust shaken off by the brush is discharged from the inside to the outside by the blower fan of the air conditioning device through an opening, a damper, and a damper opening / closing means, thereby eliminating the need for the user to clean or replace the filter.

[0024] Hereinafter, a preferred embodiment of a filter according to the present invention will be described in detail with reference to the attached drawings.

[0025] Fig. 1 is a perspective view of the filter of the present invention, Fig. 2 is an exploded view of the filter of the present invention and a plan view for showing the operating state of the filter of the present invention, and Fig. 4 is a reference view for showing the operating state of a damper in the present invention.

[0026] First, it should be noted that, among the drawings, identical components or parts are indicated by identical reference numerals, where possible. Furthermore, in describing the present invention, detailed descriptions of related known functions or configurations are omitted to avoid obscuring the gist of the present invention.

[0027] The filter of the present invention comprises a frame (130) for installing a motor (160) and having an opening (140) through which dust can be discharged, a dust collecting net (120) attached to the frame (130) excluding the opening (140), a brush (170) that is rotated by the motor (160) so as to be in close contact with the dust collecting net (120) and to shake off dust, a damper (150) formed in the opening (140) so as to block the opening (140) by its own weight, its own weight, or the elasticity of a spring (180), and a damper opening / closing means (153) formed on one side of the brush (170) to open the damper (150).

[0028] The above damper (150) is composed of an opening plate (151) for blocking an opening (140) and a shaft (152) formed on both sides of the opening plate (151). The shaft (152) is configured to allow the damper (150) to rotate. In the present invention, the shaft can be formed in various structures such as a hinge or a bracket. As long as the damper can block the opening (140) without being separated from the opening (140) and can be opened by the pushing action of the brush (170), the shape and structure of the shaft are not a problem.

[0029] Eventually, the damper (150) is pushed by the brush (170) through the damper opening / closing means, thereby opening the opening (140), and the dust from the dust collecting nets that the brush (170) has shaken off by the suction pressure of the blower fan of the air conditioner or the like can be discharged to the outdoors through the opening (140).

[0030] The above damper opening / closing means (153) may be configured as a bristles of a brush (170), or a pusher (153b) installed on one side of the brush (170) to push and open the damper (150), but any configuration that allows the damper (150) to be pushed and opened when the brush (170) rotates may be used.

[0031] That is, the hair formed on the brush (170) usually acts to shake off dust collected in the dust collecting net (120), but when passing through the damper (150), it is structured to push the damper (150) by the elasticity of the hair itself, and because of this, it is structured to open the damper (150), and can also act as a damper opening / closing means (153).

[0032] However, the most preferable configuration is a pressing member (153b) that is rotatably connected to one side of the main body (171) of the brush (170) by an axis (153a), and the pressing member (153b) may also be provided with a spring (153d). The spring (153d) applies a force that pushes the pressing member (153b) to one side due to elasticity, and when the pressing member (153b) passes the damper (150), the damper (150) is pushed, so that it can be easily and stably opened.

[0033] At this time, it is desirable to form a wheel (153c) at the end of the above-mentioned pressing member (153b) so that it does not get caught or friction is applied and it can roll easily.

[0034] At this time, another damper opening / closing means (153) may be configured as a pressing plate (not shown) having an inclined protrusion formed on one side of the main body (171) of the brush (170) that exerts elasticity. At this time, the inclined protrusion is configured to have a different inclination depending on the direction of travel of the brush (170), and since the inclined protrusion has a structure that is initially low and gradually increases, the opening (140) can be opened at the moment when the inclined protrusion presses the damper (150) when the brush (170) rotates.

[0035] In this way, if the damper (150) that blocks the opening (121) in the present invention has a structure that can only be opened by driving the brush (170), it is natural that this falls within the technical category of the damper opening / closing means (153) of the present invention.

[0036] In this way, the present invention is structured so that when the opening (140) is opened, dust removed from the dust collecting net (120) by the brush (170) due to the suction pressure of the blower fan (not shown) of the air conditioner can escape together with the suctioned air through the open gap of the damper (150), i.e., the opening (121) of the dust collecting net (120), and be discharged outdoors.

[0037] Therefore, the present invention has a structure that automatically cleans the filter and discharges dust outdoors, so that the user does not need to clean or replace the filter, and as a result, indoor air discharge efficiency can be very good.

[0038] It is preferable that the filter of the present invention above be configured to surround the outside of the frame (130) with a circular edge portion (110), and the frame (130) has a structure in which a plurality of edges extend inward from the edge portion (110), thereby enabling the frame (130) to stably support the motor (160) and the dust collecting net (120).

[0039] The above frame (130) has a structure in which a motor shaft penetrates the center and is connected to the shaft (161) of a brush (170) by penetrating the center of a dust collecting net (120).

[0040] In addition, a hole (121) must be formed on one side of the dust collecting net (120) so that an opening (140) is formed in the hole (121). At this time, the shape of the dust collecting net (120) is preferably circular, because the brush (170) must shake off dust stuck to one side of the dust collecting net (120) while rotating by the motor (160).

[0041] It is preferable that a dust removing means (172) be formed on one side of the above brush (170) to remove dust adhering to one side of the dust collecting net (120) without damaging the dust collecting net (120). The dust removing means may be made of mohair, a soft resin plate, a rubber plate, or the like.

[0042] The above-described frame portion (110) may be provided with a coupling means (111) for coupling to one side of an external air inlet of an air conditioner (not shown). The coupling means formed in the frame portion (110) may include a screw hole for fastening a screw when coupling with a screw, a circular connecting hole protruding on the inside of the external air inlet may be formed to couple in a forced fit manner, and may be coupled by being caught by each other using a known coupling and latching means, or a spiral portion may be formed to couple these in a screw coupling manner. In addition, it goes without saying that various known coupling means may be used.
