Filter structure capable of removing dust

Abstract

The objective of the present invention to provide a filter structure capable of removing dust, comprising: 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 means of 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. The present invention has the effect that a dust removing means of the brush can be continuously shaken off by the concave groove part formed on one side of the dust collection net, such that the dust can be efficiently removed without the brush dragging around and rotating the dust. Particularly, the dust introduced into an air conditioner is blocked from an outdoor air inlet in advance to prevent the dust from entering an air conditioner case, thereby preventing dust collecting efficiency from being deteriorated.

Description

technical field [0001] The present invention relates to a filter structure capable of removing dust, and more particularly to a filter structure for effectively removing dust collected by the filter installed inside an outside air suction port of an air conditioner. Background technique [0002] In general, recently built buildings put a lot of effort into insulation for energy savings and a lot of attention to ventilation for health reasons. [0003] Therefore, in order to meet the requirements of heat insulation and ventilation at the same time, building air-conditioning (ventilation) devices are used, which can forcefully inhale and discharge indoor air and external air through ventilation fans, and use filters or heat exchange devices to achieve air purification and ventilation. In order to save energy, and to effectively use space, the building air conditioners are mostly installed on the ceiling, and indoor air and outdoor air are sucked in and discharged through pipes...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned conventional air conditioner is only a structure in which a filter is installed on the side of the heat exchanger to remove dust flowing into the heat exchanger, so it does not have the ability to block the inflow of dust into the air conditioner or to block and remove it in this way. or any unit that removes accumulated dust, so there is a problem that the inside of the air conditioner becomes dirty and eventually becomes the cause of indoor air pollution inevitably

[0006] In particular, since the brush that rotates close to the dust collection net of the filter is in the state of continuing to clean the dust while rotating, it also has the disadvantage that the dust is not easy to discharge and the filtering function of the filter net is reduced.
