As shown in FIG. 1, the ionizer charging unit 500 charges foreign substances (fine dust, etc.) contained in the air flowing along the first duct unit 100a, so that the flowing air is converted into the heat exchange filter unit. It should be captured in the process of passing through (300).

To this end, the ionizer charging unit 500 is disposed in the front side of the heat exchange filter unit 300 inside the first duct unit 100a, so that charged particles in the flowing air are collected from the dust collecting filter unit 320 After being filtered through through, it is allowed to be inhaled or exhausted.

On the other hand, the ionizer charging unit 500 is provided with a plurality of discharge needles 511 protruding on both sides, as shown in FIG. 5, are arranged so as to face each other, the flow direction of air and both sides are parallel to each other. And a discharge electrode 510 provided in such a manner that a power supply unit (not shown) supplies a voltage to the discharge electrode 510.

At this time, both ends of the discharge electrode 510 in the width direction are formed in a sawtooth shape, and a plurality of protrusions are formed at both ends in the width direction.

According to the above configuration, when air passes through the ionizer charging unit 500 in a state in which high-voltage power is applied, corona discharge occurs by the discharge electrode 510 and foreign matter contained in the air is prevented from being Depending on the polarity of the power applied to the electrode 510, it is charged to the + electrode or the negative electrode, and the charged air flows to the heat exchange filter unit 300.

As shown in FIGS. 5 to 7, the heat exchange filter unit 300 performs heat exchange while passing through the heat exchange filter unit 300 rotating in the process of inhaling or exhausting air, while foreign substances are transferred to the heat exchange filter unit ( It is intended to be filtered by 300, and includes a body frame 310 and a dust collecting filter unit 320.

The body frame 310 is formed in a wheel shape in which a plurality of support members 312 connecting between the central axis body 220 and the outer circumferential surface are arranged radially with respect to the central axis body 220, and the central axis The power unit 600 is formed protruding from the center of the body 220 to the outdoor side and is formed to protrude from the center of the central shaft body 220 to the indoor side and the first driving shaft 313 hinged to the separating part 200.

Accordingly, the body frame 310 may be rotated by the power unit 600 in a stable hinge-fastened state with the separating unit 200.

At this time, as shown in FIG. 5, a ball plunger 210 is provided in the coupling groove 240 so that the heat exchange filter unit 300 rotates in a more stable state, and the drive shaft 313 is the ball It is rotated in a state supported by the plunger 210.

In addition, as shown in Figs. 6, 7, 10 to 12, a first gas tight protrusion 314 protruding outwardly along the outer circumference is formed on the outer circumferential surface of the body frame 310, and the heat exchange duct The second gas tight protrusion 110 is formed in the part 100 to be rotatably fastened while the first gas tight protrusion 314 is engaged.

At this time, as the frictional force generated between the first gas tight protrusion 314 and the second gas tight protrusion 110 and the frictional force generated between the ball plunger 210 and the drive shaft 313 are smaller, the body frame ( 310) can be rotated easily.

Therefore, one outer surface selected from the first gas tight protrusion 314 and the second gas tight protrusion 110, and one outer surface selected from the ball plunger 210 and the drive shaft 313 is PTFE, polyimide, PEEK, PPS. , Nylon, acetal, or PET.

The above-described material has a low coefficient of friction and has an effect of having abrasion resistance even under a non-lubricating condition, and thus has a characteristic that allows the heat exchange filter unit 300 to rotate more easily.

The dust collecting filter unit 320 is configured to collect foreign substances in the air charged by the ionizer charging unit 500 and is provided in a space between a pair of support members 312 adjacent in the circumferential direction. Specifically, the dust collecting filter unit 320 includes a HEPA filter or an electrostatic filter 320b.

The HEPA filter is an air filter that removes dust in the air and has a collection capacity of 88 to 99.978% or more for 0.3 μm particles depending on the grade, and the filter paper of the filter refers to a filter mainly formed of glass fibers of 1 to 10 μm or less. .

In this HEPA filter, foreign matter is filtered as foreign matter collides with the fibrous tissue forming it. As described above, foreign matter contained in the air flowing to the heat exchange filter unit 300 is charged with + or-polarity. It is supplied to the dust collecting filter unit 320 in a state, so that filtering can be performed more effectively.

Meanwhile, in the electrostatic filter, the electrostatic filter filters foreign substances contained in air, which is formed in a form in which fibers having a plurality of vortex forming protrusions formed on a surface thereof are stacked.

At this time, the electrostatic filter consists of forming a plurality of layers by winding a charged filter fabric, and the filter fabric is manufactured by applying heat to the fiber fabric to charge it, manufactured by frictional charging, It may be composed of a thing manufactured by various methods, such as a thing charged with light energy, a film after charge treatment, and then pulverized into a filter shape, and a product manufactured by corona discharge, and the electrostatic filter As a filter having electrical properties, when the electrostatic filter is used as the dust collecting filter unit 320, there is an effect of further improving the collecting efficiency of foreign substances in charged air.

Meanwhile, the filter fabric includes a plurality of irregularly arranged vortex forming protrusions.

The vortex forming protrusion forms a plurality of flow paths between the filter fabrics while the filter fabric is wound, and increases a contact area between the filter fabric and air passing through the dust collecting filter unit 320.

As a result, the air passing through the electrostatic filter collides with the eddy current forming protrusion and sufficiently stays inside the electrostatic filter before passing through, thereby increasing the heat exchange efficiency, and the effect of improving the filtration efficiency of foreign matters due to the increase of the contact area. have.

On the other hand, the vortex forming protrusion is to be manufactured by a protrusion forming roller, the protrusion forming roller is made in the form of a roller in which a plurality of protrusions are irregularly arranged along an outer circumferential surface, and is pressed while rolling the surface of the filter fabric. As a result, a plurality of vortex-forming protrusions are formed.

At this time, the diameter of the vortex forming protrusion is formed to be 2 ~ 5mm. When the diameter of the vortex forming protrusion is less than 2 mm, there is a problem that it is difficult to sufficiently exhibit heat exchange efficiency and filtration efficiency due to an increase in the contact area, and when the diameter of the vortex forming protrusion exceeds 5 mm, the dust collecting filter unit 320 is There is a problem in that air circulation is not properly performed due to obstruction of the flow of air passing through.

Therefore, the diameter of the vortex forming protrusion is preferably formed within the range of 2 ~ 5mm.

On the other hand, 50 to 100 vortex forming protrusions are formed per 10 cm2 of area. When less than 50 vortex forming protrusions are provided per 10 cm2 of area, there is a problem that heat exchange efficiency and filtration efficiency are deteriorated due to a small contact area. When more than 100 are provided per 10 cm2 of area, passing through the electrostatic filter There is a problem that hinders the flow of air.

Therefore, it is preferable that the vortex forming protrusions are formed within a range of 50 to 100 per 10 cm2 of area.

Meanwhile, as described above, the electrostatic filter is provided between a pair of support members 312, which is generally formed in a fan shape.

In this case, the cutting blade for cutting the filter fabric is heated to a temperature corresponding to the melting point of the fabric according to the type of the filter fabric. It is made to cut the wound filter fabric in the state.

Accordingly, the filter fabric can be cut while the cut surface is melted and bonded.

A plurality of the second fixing means 315b are formed to protrude from the other end of both ends in the front-rear direction of the support member 312b, and the protruding end is bent toward one end in the front-rear direction of the support member 312b.

That is, the second fixing means 315b is formed in the same manner as the first fixing means 315a, and a plurality of the bent ends are provided on the support member 312b facing the first fixing means 315b. .

At this time, the bent ends of the first fixing means 315a and the second fixing means 315b are formed in a hook shape.

According to the above configuration, the dust collecting filter unit 320 may be firmly fixed by the first fixing means 315a and the second fixing means 315b.

Referring to FIG. 8, in a state in which one surface of the dust collection filter part 320 faces the first fixing means 315a and the other surface faces the second fixing means 315b, the dust collection filter part When the rotation 320 is rotated, the bent ends of the first fixing means 315a and the second fixing means 315b are respectively inserted into the dust collecting filter 320 and fixed.

At this time, since the ends of the first fixing means 315a and the second fixing means 315b are formed in a wedge shape, the dust collecting filter unit 320 is in a firmly fixed state in which the dust collecting filter unit 320 is not separated.

Meanwhile, the thickness of the dust collecting filter unit 320 and the body frame 310 are formed to correspond to each other so that the surface of the heat exchange filter unit 300 can be formed flat.

Incidentally, the closing part 317 is formed in a space between a pair of support members 312 adjacent to each other so that the space in front and the space in the rear of the body frame 310 is blocked. A pair is formed.

According to the above configuration, the closing part 317 is between the dust collecting filter part 320 located at the side of the second duct part 100b and the dust collecting filter part 320 located at the side of the first duct part 100a. As a result, it is possible to prevent a phenomenon in which the air discharged to the outside is moved back to the first duct part 100a in the process of passing through the dust collecting filter part 320 and re-enters the room.

On the other hand, as shown in Figure (7b), as the support member 312 of the heat exchange filter unit 300 is disposed radially with respect to the central axis in an inclined state, the body frame 310 is It can take shape.

Accordingly, the electrostatic filter unit 320 may be detached more easily.

On the other hand, in the present invention, the first duct part 100a divided by the separating part 200 allows intake of outdoor air, and the indoor air is exhausted through the second duct part 100b. When a space is generated between the separating unit 200 and the heat exchange filter unit 300, the first duct unit 100a and the second duct unit 100b are not completely partitioned, so that the intake or exhausted air is exhausted or Inhalation may occur.
