Description

The air-conditioner outdoor unit automatic dust removing apparatus

Technical field

The utility model relates to a kind of air-conditioner, especially a kind of air-conditioner outdoor unit automatic dust removing apparatus.

Background technology

Common air-conditioning off-premises station (hereinafter to be referred as off-premises station) all is installed in the open air, generally can not have automatic dedusting function, and long-play can make off-premises station heat exchanger laying dust, has hindered the inner air of device off-premises station and has flowed, and has a strong impact on the heat exchange effect of off-premises station.Off-premises station is mounted in places such as balcony, windowsill, exterior wall mostly in addition, limited by the installation site, is difficult to air-conditioner outdoor unit is cleaned.If please the professional person clean, not only can increase user's expense expenditure, and there is certain danger in work high above the ground.

Chinese patent document number CN201110054457.7 discloses " a kind of air intake filter screen device and clean method thereof of air-conditioner outdoor unit " on November 9th, 2011 at present, and this device can be realized the cleaning of air intake screen pack automatically; But this apparatus structure stability is not high, and the long-time running filter screen can be because of the lax distortion of self gravitation reason, and it will be no longer tight that two row's square openings on the air intake filtration selvage cooperate with the ratchet gear teeth; This device assembly technology is complicated in addition, needs to remove the part casing of outdoor, just the air intake filter screen device can be installed.Therefore, be necessary to do further improvement and perfect.

Summary of the invention

The utility model purpose is to overcome the deficiency of above-mentioned prior art and provides a kind of simple in structure, and air-conditioner outdoor unit automatic dust removing apparatus stable and reliable for performance can effectively prolong service life of off-premises station.

A kind of off-premises station automatic dust removing apparatus by this purpose design; Comprise the screen pack that places the outer inlet side of casing of outdoor; It is characterized in that also comprising roller brush, No. two roller brushes, rotating shaft and traction elements, wherein said roller brush and No. two roller brushes through two upper brackets rotate be installed in casing of outdoor above or below, below that is installed in casing of outdoor or top that said rotating shaft is rotated through two lower carriages; Being set in outside roller brush and the rotating shaft of said screen pack tensioning; The bristle of a roller brush passes the mesh of screen pack, the surface that the bristle of No. two roller brushes streaks screen pack, and said traction element drives a roller brush and No. two roller brushes rotate.

Said roller brush prolongs horizontal direction to be placed, and said No. two rollers brush prolongs horizontal direction to be placed, and said rotating shaft is prolonged horizontal direction and placed.

Said traction element comprises motor, driving gear, first driven gear and second driven gear; Wherein said motor is installed on the upper bracket; Said driving gear is installed in the rotating shaft of motor and is coaxial, driving gear respectively with first driven gear and the engagement of second driven gear; Said first driven gear is fixedly mounted on the end of roller brush and is coaxial; Said second driven gear is fixedly mounted on the end of No. two rollers brush and is coaxial.

The utility model beneficial effect compared with prior art is: with the screen pack tensioning, can effectively offset the lax distortion that causes because of gravity with roller brush of horizontal direction and rotating shaft.Pass the mesh of screen pack with the bristle of roller brush, drive screen pack and rotate, stable and reliable for performance.The user need not to remove shell and can install, and is simple to operation, simple in structure.Manufacturer need not die sinking again, only needs the existing outer casing mold of change, has reserved the position, hole in the relevant position, and the position that perhaps has openning hole in existing shell relevant position gets final product, thereby has reduced production cost, can effectively prolong the service life of off-premises station.
