On the other hand, as shown in FIGS. 2 and 3 , the separation unit 200 has a sawtooth cross-section to increase a contact area with air passing through the first duct part 100a and the second duct part 100b. It may be made of a bent or curved plate material such as a shape, a wave pattern shape, an uneven shape, and the like.

In other words, as shown in FIG. 2 , when the heat exchange duct part 100 is formed in a curved shape, when the separation part 200 is formed of a flat plate, the heat exchange duct part 100 completely matches the state. There is a problem in that it is difficult to install or manufacture it, and in particular, when a tolerance occurs, there is a problem in that the installation of the separation unit 200 itself is impossible.

Therefore, in the present invention, when the heat exchange duct part 100 is formed in a curved shape, the separation part 200 is made of a bent or curved plate material in a wave pattern, sawtooth pattern, uneven shape, etc., so that the contact area with the flowing air By increasing the heat exchange efficiency can be further improved.

In addition, when a tolerance is generated between the separation part 200 and the heat exchange duct part 100, the bent or bent plate material compensates for the tolerance, so that the mutual configuration can be easily combined even when tolerances and errors occur. have.

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 transferred to the heat exchange filtering unit. (300) to be collected in the process of passing.

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

On the other hand, as shown in FIG. 5 , the ionizer charging unit 500 has a plurality of discharge needles 511 protruding from both sides, and the plurality of discharge needles 511 are arranged to face each other, and the air flow direction and both sides are parallel to each other. It includes a discharge electrode 510 provided in the form of a power supply and a power supply unit (not shown) for supplying 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 of the discharge electrode 510 in the width direction.

According to the above configuration, when air passes through the ionizer charging unit 500 in a state in which a high-voltage power is applied, corona discharge occurs by the discharge electrode 510 and foreign substances contained in the air are released into the protrusion-shaped crystal. Depending on the polarity of the power applied to the electrode 510, the positive electrode or the negative electrode is charged, and the charged air flows to the heat exchange filtering unit 300 .

5 to 7, the heat exchange filtering unit 300 performs heat exchange while passing through the heat exchange filtering unit 300 rotating in the process of air intake or exhaust, while foreign substances are removed from the heat exchange filtering unit ( 300), and includes a body frame 310 and a dust collecting filter unit 320.

The body frame 310 has a wheel shape in which a plurality of support members 312 connecting between the central shaft body 311 and the outer circumferential surface are radially arranged with respect to the central shaft body 311, and the central shaft The first driving shaft 313 is formed to protrude from the center of the body 311 to the outside and is hingedly coupled to the separation unit 200, and the central shaft body 220 is formed to protrude from the center of the body 220 to the interior, and the power unit 600 and a second drive shaft 316 coupled to the shaft.

In other words, a coupling groove 240 is formed at one end of the first separating portion 200a, and the first driving shaft 313 is hinged while being inserted into the coupling groove 240, and the second separation A power unit 600 is fixedly provided at an upper portion of one end of the unit 200b and is coupled to the second driving shaft 316 .

Accordingly, the body frame 310 may be rotated by the power unit 600 while being stably hinged with the separation 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 filtering unit 300 rotates in a more stable state, and the driving shaft 313 is the ball It is rotated while being supported by the plunger 210 .

In addition, as shown in FIGS. 6, 7, and 10 to 12 , a first airtight protrusion 314 protruding outward along the outer periphery is formed on the outer circumferential surface of the body frame 310, and the heat exchange duct A second hermetic protrusion 110 is formed on the part 100 to be rotatably fastened while the first hermetic protrusion 314 is engaged.

The air passing through can pass through the heat exchange filtering unit 300 to flow inside or outside.

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

Therefore, one outer surface selected from the first air tight protrusion 314 and the second air tight protrusion 110 and one outer surface selected from the ball plunger 210 and the drive shaft 313 have PTFE, polyimide, PEEK, and PPS. , to be coated with one material selected from nylon, acetal or PET.

The material has a low coefficient of friction and has the effect of having abrasion resistance even under a non-lubricating condition, so that the heat exchange filtering unit 300 can be rotated 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 is formed of 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 ~ 99.978% or more for particles of 0.3㎛ depending on the grade, and the filter paper of the filter means a filter mainly formed of glass fiber with a diameter of 1 ~ 10㎛ or less .

The HEPA filter filters foreign substances as foreign substances collide with the fibrous tissue forming them. As described above, the foreign substances contained in the air flowing into the heat exchange filtering unit 300 are positively or negatively charged. As it is supplied to the dust collecting filter unit 320 in a state of being, filtration can be performed more effectively.

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

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

On the other hand, the filter fabric includes a plurality of irregularly arranged vortex forming protrusions.

The vortex forming protrusion not only forms a plurality of flow paths between the filter fabrics in a state in which the filter fabric is wound, but also increases the contact area between the filter fabric and the air passing through the dust collecting filter unit 320 .

As a result, the air passing through the electrostatic filter collides with the vortex-forming protrusion and sufficiently stays inside the electrostatic filter before passing through, increasing heat exchange efficiency, and the filtration efficiency of foreign substances is also improved due to an increase in the contact area. have.

On the other hand, the vortex forming protrusion is manufactured by a protrusion forming roller, and the protrusion forming roller is formed in the form of a roller in which a plurality of protrusions are irregularly arranged along the 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 heat exchange efficiency and filtration efficiency due to an increase in contact area are difficult to be sufficiently exhibited, and when the diameter of the vortex forming protrusion exceeds 5 mm, the dust collecting filter unit 320 There is a problem in that the air circulation is not performed properly by obstructing the flow of air passing therethrough.

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

Meanwhile, 50 to 100 of the vortex forming protrusions are formed per 10 cm 2 of the area. When the number of vortex forming protrusions is less than 50 per 10 cm 2 of area, there is a problem in that heat exchange efficiency and filtration efficiency are low due to a small contact area, and when provided in excess of 100 per 10 cm 2 of area, the electrostatic filter passes through There is a problem that obstructs the flow of air.

Therefore, it is preferable that the vortex-forming protrusions are formed within the range of 50 to 100 per 10 cm 2 of area.

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

Therefore, in the present invention, an electrostatic filter is formed by cutting the wound filter fabric in a sector shape. At this time, 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 in an adhered state while the cut surface is melted.

The 312 is provided with a plurality of first fixing means (315a) and second fixing means (315b).

In other words, a plurality of the first fixing means 315a are formed to protrude from one end of the front and rear ends of one support member 312a among a pair of support members 312a and 312b adjacent in the circumferential direction. The end is bent toward the other end in the front-rear direction of the support member 312a.

A plurality of 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 ends are 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 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 collecting filter unit 320 faces the first fixing unit 315a and the other surface faces the second fixing unit 315b, the dust collection filter unit is disposed. When the 320 is rotated, the bent ends of the first fixing means 315a and the second fixing means 315b are fixed while being inserted into the dust collecting filter part 320 , respectively.

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

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

On the other hand, as shown in Figure 7 (a), the body frame 310 may further include a closing portion (317).

In other words, the closure part 317 is formed in the space between a pair of adjacent support members 312 so that the front space and the rear space of the body frame 310 are blocked. A pair is formed.

According to the above configuration, the closure part 317 is between the dust collecting filter part 320 located on the side of the second duct part 100b and the dust collecting filter part 320 located on the side of the first duct part 100a. is blocked, thus preventing the air discharged to the outside from flowing back into the room while moving back to the first duct part 100a in the process of passing through the dust collecting filter part 320 .

On the other hand, as shown in Fig. 7b, the support member 312 of the heat exchange filtering unit 300 is radially disposed with respect to the central axis in an inclined state, so that the body frame 310 is a kind of rotary blade. can take shape.

Accordingly, detachment of the electrostatic filter unit 320 may be performed more easily.

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