Preferably, the filtering holes in the middle of the dust filtering cover are distributed in a criss-cross mode, and the middle of the dust filtering cover is hollowed out.

Preferably, the side edge of the dust filter cover is not contacted with the flow guide hole.

Preferably, the diameter values of the diversion holes increase from inside to outside in sequence.

Preferably, the side edge of the dust hood and the two side surfaces of the partition plate are respectively provided with a suction rod and a suction groove, and the suction rod is sleeved in the suction groove to fix the dust hood.

The utility model provides a pair of air inlet dust filter structure for central air conditioning unit, beneficial effect lies in:

at the air conditioner air inlet, when wind passed the dust filter, carry out electrostatic absorption and store to the dust that carries in the wind through the dust filter, the effectual dust that carries in the wind that has reduced through the dust filter improves the cleanliness and the life of dust filter, can clear up the dust that holds the chamber and hold the chamber wall in chamber that store in the while is instant.

The utility model discloses simple structure, the simple operation, solution prior art that can be fine dust filter cover can carry out certain filtration, separation to rubbish such as dust that mix with in the wind, but in the long-time work of air conditioner, carries a large amount of dusts, dirt in the wind and directly leads to the filtration pore to block, reduce the refrigeration efficiency of air conditioner, increases the shortcoming of energy consumption, has stronger practicality.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, an air intake dust filter structure for a central air conditioning unit comprises an outer frame plate 1, a partition plate 2 and a dust filter 3, wherein the middle part of the outer frame plate 1 is provided with a containing cavity 4 for containing dust, an electrostatic plate 5 for adsorbing and guiding dust is arranged in the cavity 4, a flow guide hole 41 and a flow guide outlet 42 which are communicated with the cavity of the cavity 4 are respectively arranged on the inner cavity wall of the outer frame plate 1, when air enters the air conditioner and passes through the dust filter 3, the electrostatic plate 5 carries out electrostatic adsorption on dust carried in the air passing through the dust filter 3, make the dust dispersion that carries in the wind store in holding the chamber 4 through the suction of water conservancy diversion hole 41 under the effect of electrostatic absorption, the effectual dust that carries in the wind that has reduced through dust filter 3 improves dust filter 3's life, and it can to hold the chamber wall of the dust that stores in the chamber 4 and holding chamber 4 through opening export 42 at last.

The filtration pore vertically and horizontally staggered who strains the 3 middle parts of dirt cup distributes, and strains the middle part fretwork of dirt cup 3, link up the in-process that dirt cup 3 flows at wind, the dirt cup 3 of fretwork, vertically and horizontally staggered's filtration pore has further improved the dust that electrostatic plate 5 carried in to wind and has carried out electrostatic absorption's sufficiency.

The side of dust filter 3 does not contact with water conservancy diversion hole 41, prevents that the side from blocking water conservancy diversion hole 41 after dust filter 3 installation is accomplished, influences the normal absorption of dust, the processing work.

The diameter values of the flow guide holes 41 from inside to outside are sequentially increased, when the air conditioner works, air has a certain flow velocity to enable dust to enter the accommodating cavity 4 through the flow guide holes 41 for storage, and the gradually-changed inner diameter value of the flow guide holes 41 effectively prevents the dust from moving reversely and moving out of the accommodating cavity 4.

The side of the dust hood 3 and the two side faces of the partition board 2 are respectively provided with a suction rod 31 and a suction groove 21, the suction rod 31 is sleeved in the suction groove 21 to fix the dust hood 3, when the dust hood 3 is fixed, the suction rod 31 is directly inserted into the suction groove 21, the relative position of the suction rod 31 and the suction groove 21 is reinforced under the action of adsorption force, the stability and the convenience of installation of the dust hood 3 are improved, and the suction rod 31 and the suction groove 21 have opposite magnetism to enable the suction rod 31 and the suction groove 21 to attract each other.

The working principle is as follows:

first, the suction rod 31 is inserted into the suction groove 21, the dust filter 3 is slightly bent during the insertion, the relative position between the suction rod 31 and the suction groove 21 is reinforced by the suction force, and the dust filter 3 is installed between the outer frame plate 1 and the partition plate 2.

At the air conditioner air inlet, when wind passed dust filter 3, electrostatic absorption was carried out to the dust that carries in the wind through dust filter 3 to electrostatic plate 5, make the dust dispersion that carries in the wind store in holding the chamber 4 through the suction of water conservancy diversion hole 41 under the effect of electrostatic absorption, the effectual dust that carries in the wind that has reduced through dust filter 3, improve dust filter 3's life, at last through opening export 42 to holding the dust that stores in the chamber 4 and holding the chamber wall of chamber 4 and clearing up and can be can

Although embodiments of the present invention have been shown and described in the description of the present invention, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made herein without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
