The present invention relates to a ventilation device, and more particularly, to provide an included ventilation device to which the fixing structure of the filter to which the air purification filter can be mounted simply and accurately is applied.

The air in an enclosed space increases the carbon dioxide content over time due to the breathing of living things, which interferes with the breathing of living things. Therefore, if many people stay in a narrow space such as an office or a vehicle, it is necessary to frequently replace the indoor air with fresh air. At this time, a commonly used ventilation device.

Most conventional ventilation apparatuses employ a method of forcibly discharging only indoor air to the outside using a single blower. However, in the case of forcibly discharging only indoor air by using one blower, the indoor cold air or heat is discharged to the outside without filtration, and the indoor air is heated without the heat exchange through the door or the window gap. And the cost of cooling has become unnecessarily high.

In addition, due to the sudden inflow of cold air and heat from inside to outside people suddenly change the temperature of the interior people there is unpleasant feelings, especially in the state that the indoor window or door frame closed to discharge only the indoor air to the outside In this case, the inflow of fresh air may be blocked and oxygen deficiency may occur, and the humidity of the indoor air is not controlled at all. However, even though a ventilation device is provided, it does not maintain a comfortable indoor environment. there was.

In order to solve this problem, a total heat exchange type ventilator for exchanging outdoor air with indoor air discharged to the outside and then supplying the indoor air has been proposed.

1 is a schematic diagram schematically showing a structure installed in a room in which a general electrothermal exchange ventilator and an air cleaner are separated, and FIG. 2 is a schematic diagram illustrating a structure of a ventilator according to the related art.

1 and 2, an air supply duct 10 for guiding outdoor air to the inside of the box-shaped case 1 is provided. The air supply duct 10 intersects with the air supply duct 10 at a predetermined position. The exhaust duct 20 is guided to the outdoor is provided.

In addition, an electric heat exchanger (5) is provided in which heat is exchanged between the outdoor air that is supplied at the point where the air supply duct 10 and the exhaust duct 20 intersect and the indoor air that is exhausted.

At this time, the air supply duct 10 and the exhaust duct 20 are not interfered with each other by the partition 3 partitioning the inside of the case 1 up and down.

An air supply inlet 11 is formed at one end of the air supply duct 10 to communicate with the outside, and an air supply outlet 13 is formed to communicate with the room at the other end thereof, and an air exhausted to communicate with the room at one end of the exhaust duct 20. An intake port 21 is formed and an exhaust outlet 23 is formed at the other end in communication with the outdoors.

An air supply fan 15 is provided on the air supply outlet 13 of the air supply duct 10 to forcibly suck outdoor air, and is made of a nonwoven fabric to filter various contaminants in the outdoor air supplied to the air supply inlet side. An air purification filter 30 is provided, and an exhaust fan 25 for forcibly discharging indoor air is provided on the exhaust inlet 21 of the exhaust duct 20.

On the other hand, the heat exchanger (5) has a cube shape in which the upper and lower edges are supported by the case (1) and the left and right edges are supported by the partition wall (3), and a plurality of air supply passages communicating with the air supply duct (10) therein. A plurality of exhaust passages 5b adjacent to 5a and the air supply passage 5b and communicating with the exhaust duct 20 are provided.

Although not shown, a heat exchange film (not shown) having excellent heat conduction efficiency is provided at a boundary portion between the air supply passage 5a and the exhaust passage 5b.

At this time, the portion shown by the solid line is the air supply passage 5a and the portion shown by the dotted line is the exhaust passage 5b.

Referring to the operation of the electrothermal exchange system ventilator configured as described above are as follows.

First, when indoor air is contaminated to some extent, power is supplied to the exhaust fan 25 and the indoor air flows into the exhaust duct 20 through the exhaust inlet 21, and then the exhaust passage 5b of the total heat exchanger 5. ) Is discharged to the outside through the exhaust outlet (23).

At the same time, while the power is supplied to the air supply fan 15, fresh outdoor air flows into the air supply duct 10 through the air supply inlet 11, and then passes through the air supply passage 5a of the heat exchanger 5, and the air supply outlet ( 13) is introduced into the room.

At this time, the indoor air and the outdoor air passing through the heat exchanger (5) is heat exchanged through the heat exchange membrane.

Specifically, the heat exchange occurring in the total heat exchanger 5 includes sensible heat exchange occurring between the supplied outdoor air and the exhausted indoor air, and the hot air in the indoor air or the outdoor air has a dew point temp. It is made of latent heat exchange by the condensate produced in the following state.

As described above, in the case of the electrothermal exchange ventilator, the outdoor air supplied when the room is cooled or heated is primarily heat-exchanged with the indoor air and then introduced into the room, thereby preventing a sudden rise or fall of the room temperature. Can be.

However, the conventional heat exchanger ventilation apparatus is installed in a state in which the heat exchanger is set up in a lozenge shape, and the air supply fan and the exhaust fan are also installed in a direction perpendicular to the ground, so that the height thereof is about 300 mm or more and the space is large. There is a problem that is difficult to install in a limited ceiling, and when installed in the ceiling has a problem that the ceiling height is lowered.

Therefore, in apartments, etc., a separate space is provided on the veranda and installed therein, which occupies the space of the apartment, thereby increasing the installation cost and causing user dissatisfaction. When the ultra-thin design is installed, the height of the flow path through which the indoor and outdoor air flows is also lowered, which increases the flow resistance, which leads to the necessity of a structure capable of minimizing the resistance of the air flowing in the ventilation system.

On the other hand, the air purification filter that filters foreign substances contained in the air sucked from the outside is made of a nonwoven fabric with low suction resistance, and thus serves as a pre-filter for filtering dust of relatively large particles, thus preventing fine dust from being filtered. There is a problem that the air can be contaminated. When the HEPA (High Efficiency Particulate Arrestor) filter or the like is applied to the air purification filter to solve this problem, the pressure loss is high, so that the static pressure to have a proper air flow Since it is increased as shown in Figure 3, there is a need for a fixing structure of the filter that can minimize the pressure loss due to the application of the HEPA filter.

In addition, since the HEPA filter is not permanent but needs to be replaced periodically, there is a need for a fixing structure of the filter that is easy to remove and install the HEPA filter.

In addition, in recent years, with increasing interest in health, there is a need for a fixing structure of a filter that can be equipped with a filter having a function of deodorization and sterilization, as well as a filter of removing foreign substances.

The present invention is to solve the above problems, an object of the present invention is to provide a ventilation device is easy to install and remove the filter, the filter fixing structure is applied to minimize the pressure loss due to the application of the filter. .

In addition, the present invention provides a ventilation device to which a filter fixing structure capable of mounting a functional filter having a function of deodorization and sterilization, etc., with a HEPA filter having a foreign material removal function.

In order to achieve the above object, the present invention forms a body; A total heat exchanger installed inside the main body; An air purifying filter installed on a passage through which outdoor air suctioned into the interior of the total heat exchanger flows; It provides a ventilation device including a fixing guide for fixing the air purification filter on the one side of the heat exchanger to be spaced apart from the heat exchanger and a predetermined interval while maintaining airtightness with the heat exchanger.

In addition, the fixing guide includes a seating portion in which the corner portion of the heat exchanger is seated; A filter installation unit to which the air purification filter is installed and fixed; And a gap maintaining protrusion for maintaining a gap between the heat exchanger and the air purifying filter. The air purifying filter installed on the surface where the outdoor air is sucked is a hepa filter. The air purification filter installed on the surface of the outdoor air is discharged is characterized in that at least one functional filter.

Therefore, according to the ventilator of the present invention, the air purifying filter can be easily installed and removed and the pressure loss due to the HEPA filter can be minimized.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the ventilator of the present invention that can specifically realize the above object.

In addition, the same components as in the prior art are given the same names and the same reference numerals for convenience of description, and description thereof will be omitted.

4 to 7c show a preferred embodiment of the ventilator of the present invention.

First, as shown in FIG. 4, an air supply duct 110 through which outdoor air is sucked from the outside and supplied to the indoor air flows, and an exhaust duct 120 through which indoor air sucked from the indoor air and discharged to the outside flows. The main body 100 is formed partitioned.

And, the heat exchanger 130 is installed inside the main body 100.

The heat exchanger (130) is a device in which heat passages are formed so that a passage (not shown) in which outdoor air sucked into the inside flows and a passage (not shown) in which indoor air discharged to the outside flows are adjacent to each other and cross each other. Since the structure is obvious to those skilled in the art, a detailed description thereof will be omitted.

In addition, as shown in FIG. 5, the air purification filter 140 is provided on a passage through which the outdoor air of the electrothermal heat exchanger 130 is sucked into the room and flows.

In addition, a fixing guide 150 for fixing the air purification filter 140 to one side of the heat exchanger 130 is provided.

The fixing guide 150 is preferably fixed to maintain the air inflow passage and airtightness so that the air purification filter 140 does not leak.

The reason for this is that if the airtightness is insufficient between the heat exchanger 130 and the air purification filter 140 and the fixed guide 150, the air supply side where the outdoor air of the ventilator is supplied to the room and the exhaust where the indoor air is discharged to the outside Leakage occurs due to the pressure difference on the side, which causes a decrease in the thermal conductivity of the heat exchanger 130, and also the smell and harmful substances discharged from the inside to the outside may be re-intake into the room through the leaked portion. Because there is.

In addition, as shown in Figure 6a, the fixing guide 150 is preferably fixed to maintain the air purification filter 140 and the heat exchanger 130 and a predetermined interval (G ₁ ).

This prevents the air purification filter 140 when the air purification filter 140 is installed in close contact with the heat exchanger 130, thereby increasing flow resistance by preventing air flow in the heat exchanger 130 by the resistance of the air purification filter itself. To do this.

On the other hand, when the air purification filter 140 is installed at a predetermined interval apart from the heat exchanger 130, the air purification filter 140 and the heat exchanger 130 between the air purification filter 140 due to the effect of the suction resistance of the air purification filter 140 Since the space acts as a kind of buffer, the suction air is diffused, so the outdoor air sucked into the heat exchanger 130 is uniformly dispersed inside the heat exchanger 130 without being biased to one side, thereby reducing the flow resistance. And the effect of improving the efficiency of heat exchange can be expected.

The fixing guide 150 is installed in each corner of the heat exchanger 130 as shown in Figure 5, in more detail, as shown in Figure 7a, the edge of the heat exchanger 130 is seated The seating portion 152 is formed, the filter mounting portion 154 is formed on the outside of the seating portion 152 is installed and fixed to the air purification filter 140, the seating portion 152 and filter mounting portion 154 It is preferably made to include a gap maintaining projection 156 is formed to protrude at the boundary of the heat exchanger 130 and the air purification filter 140 to maintain the gap.

Therefore, when the edge portion of the heat exchanger 130 is seated on the seating portion 152, and the air purification filter 140 is installed on the filter installation portion 154, the air purification filter is disposed by the gap maintaining protrusion 156. 140 and the total heat exchanger 130 to maintain a predetermined interval (G ₁ ).

On the other hand, the interval maintaining projection 156 is preferably a "┌┐" type as shown in Figure 7a, but is also applicable to the "∧" as shown in Figure 7b (157), various other forms can be applied Can be.

Here, when the air purification filter 140 is installed, the filter installation unit 154 is preferably formed to fit with the air purification filter 140 so that the airtightness and airtightness are maintained without leakage.

Here, as shown in FIG. 5, the air purification filter 140 is disposed on a surface 132 on which outdoor air on a passage through which outdoor air sucked into the interior of the heat exchanger 130 flows is sucked into the heat exchanger. In this case, the air purification filter 140 is preferably a high efficiency particulate filter (HEPA) filter 142 having excellent dust collection performance.

The HEPA filter 142 is a filter capable of removing 99.7% of particles of contaminants such as dust and bacteria of 0.3 μm or more.

In addition, instead of the HEPA filter 142, an ultra high filtration filter (Ultra Low Penetration Absoult: ULPA) filter may be used. The ULPA filter is 0.1 to 0.1 when compared with a 0.3 μm dust collecting efficiency of the HEPA filter. It is a filter that can remove 0.01㎛ fine dust, virus, mold, pollen, radon decay products and various soot particles by 99.999%.

In addition, the air purification filter 140 is disposed on a surface 134 on which the outdoor air on the opposite side where the HEPA filter 142 is installed, that is, the outdoor air on the passage through which the outdoor air sucked into the interior of the heat exchanger 130 flows, is discharged from the heat exchanger. May be installed further.

Here, the air purification filter 140 installed on the surface 134 through which the outdoor air is discharged from the total heat exchanger is a functional filter 144.

The functional filter 144 is a filter having a function of deodorizing or sterilizing air passing therethrough, and there are filters of various functions such as using activated carbon or coating a material for sterilizing the filter.

The reason for installing the HEPA filter 142 or the Wolpa filter on the outdoor air suction surface 132 of the total heat exchanger 130 is to filter the outdoor air before the outdoor air is sucked into the heat exchanger 130. This is to prevent foreign matters from accumulating inside.

However, the HEPA filter 142 or the Wolpa filter must be installed on the outdoor air suction surface 132 of the heat exchanger 130 and the functional filter 144 is installed on the outdoor air discharge surface 134 of the heat exchanger 130. The functional filter 144 may be installed on the outdoor air suction surface 132 of the heat exchanger 130 as necessary.

In addition, the functional filter 144 may be configured to exhibit a variety of functions by installing a plurality, if necessary.

In this case, the functional filters 144 are preferably installed to be spaced apart from each other by a predetermined interval G ₂ , as shown in FIG. 6B.

In addition, as shown in FIG. 7C, the filter installation unit 154 of the fixed guide 150 in which the functional filter 144 is installed to space the predetermined interval G ₂ between the respective functional filters 144. The spacer 158 may be formed to protrude from each of the functional filters 144 at predetermined intervals.

Therefore, the foreign air, such as dust, is filtered while passing through the HEPA filter 142 or the Wolpa filter before the outdoor air supplied to the room passes through the heat exchanger 130.

Each functional filter 144 passes through the functional filter 144 installed on the outdoor air discharge surface 134 of the heat exchanger 130 after heat exchange with the indoor air discharged to the outside while passing through the heat exchanger 130. After the function (deodorization, sterilization, etc.) corresponding to the function is supplied to the room.

When the outdoor air sucked here passes through the HEPA filter 142 and the functional filter 144, the HEPA filter 142 or the functional filter 144 and the heat exchanger 130 and each functional filter 144 are separated. Since it is spaced apart (G ₁ , G ₂ ) there is an effect that the flow resistance is reduced.

In addition, when the lifespan of the HEPA filter 142 and the functional filter 144 expires, the HEPA filter 142 and the functional filter 144 are removed from the fixed guide 150 after the main body 100 is opened. If the new HEPA filter 142 or the functional filter 144 is inserted into the filter installation unit 154 and then inserted, the HEPA filter 142 and the functional filter 144 are installed in the correct position, thereby making it easy to replace them. .

Referring to the effect of the ventilation device according to the present invention described above are as follows.

First, since the gap holding protrusion or the spaced protrusion is formed in the fixed guide, the space between the HEPA filter or the functional filter and the total heat exchanger and each functional filter is separated, so that the space is taken as a kind of buffer and sucked into the heat exchanger. Since the outdoor air is diffused, the outdoor air sucked into the heat exchanger is distributed to the inside of the heat exchanger without being biased to one side, thereby reducing the flow resistance and improving the efficiency of heat exchange.

Second, if the HEPA filter or the ULF filter and the functional filter are to be replaced by the end of their life, remove the HEPA filter and the functional filter from the fixed guide and insert a new HEPA filter or the functional filter into the filter installation part of the fixed guide. Since the installation is completed in the correct position due to the filter installation portion and the interval maintaining projection and the separation projection there is an effect that the exchange is easy.
