The dehumidification rotor 30 has a desiccant 35 which can adsorb and regenerate moisture in the indoor air while the indoor air passes therethrough, and a desiccant wheel 33 which wraps around the desiccant 35 and fixes the desiccant 35. ).

The desiccant 35 is wound to have a disk shape as a whole, and a fixing hole for fixing is formed at the center.

Desiccants of various shapes and materials may be used as the desiccant, but the desiccant 35 in this embodiment has a shape in which a cylindrical paper and a corrugated paper of ceramic fiber are alternately wound up in a cylindrical shape. Also, meso silica (Meso-Silica (SiO2)) has a highly developed pore and surface area, and has excellent hygroscopic properties, including nano carbon balls (NCB: Nano caboon Ball) that can be regenerated at low temperatures of about 60 ℃ or less.

The nano carbon ball (NCB) is composed of a spherical hollow core part and a mesoporous carbon cell part, and is a spherical carbon structure having a diameter of 200 nm to 500 nm. There is no pore blockage because of the large area.

Meanwhile, the desiccant 35 is a region (hereinafter referred to as a 'dehumidification region') where moisture is adsorbed as the indoor air passes and a region (hereinafter referred to as a 'regeneration region') where moisture is evaporated while the regeneration air passes. Compartment. As the desiccant 35 rotates, each area is alternately changed, so that moisture is adsorbed / evaporated.

The regeneration region is generally formed in a fan shape. The regeneration area may be partitioned to face the regeneration air heating member 60 which will be described later.

A rotor supporter 41 rotatably supporting the dehumidifying rotor 30 and a rotor frame 43 on which the rotor supporter 41 is mounted are disposed inside the main body.

The rotor frame 43 serves as a kind of barrier that divides the inside of the main body into the rear space where the blower 20 is disposed and the front space where the condensation heat exchanger 100 is disposed. The front surface of the rotor frame 43 has an opening and passes through the indoor air and the regenerated air passing through the desiccant 35. Then, an opening 43a through which the regenerated air passes through the exhaust duct 80, which will be described later, is formed.

And the upper part of the rotor frame 43 is formed in the control box mounting portion is mounted to the control box 22 for controlling the dehumidifier.

The regeneration fan 50 imparts a circulation force so that regeneration air can flow while circulating in the main body. That is, the regeneration fan 50 sucks air passing through the exhaust duct 80 and discharges the regenerated air to the regenerated air heating member 60.

The regeneration air heating member 60 heats the regenerated air discharged from the regeneration fan 90 to supply high temperature regeneration air to the dehumidification rotor 30. The regenerated air heating member 60 covers the heater 63 and the heater 63 and between the first heater cover 65 and the first heater cover 65 and the dehumidifying rotor 30 which communicate with the regeneration fan 50. Located in the, and comprises a second heater cover 61 coupled to the first heater cover (65).

The second heater cover 61 serves as a kind of air guide to prevent the air heated by the heater 63 to move toward the dehumidification rotor 30 without leaking between the heater 63 and the dehumidification rotor 30. do.

Meanwhile, the regenerated air heated while passing through the regenerated air heating member 60 passes through the regenerated zone of the desiccant 30 and then flows into the condensation heat exchanger 100. That is, the regeneration air inlet of the condensation heat exchanger 100 may be formed in communication with the regeneration area so that the regeneration air passing through the regeneration area may flow into the condensation heat exchanger 100.

However, in the present embodiment, the condensation heat exchanger 100 includes a plurality of heat exchange plates. Therefore, the dehumidifier according to the present embodiment further includes a regenerated air distribution member 90 for evenly distributing regenerated air having passed through the regeneration region to the plurality of heat exchange plates.

The regenerated air distribution member 90 is coupled to the rotor supporter 41. In addition, a rear side is opened to form a suction unit for sucking air passing through the regeneration area of the desiccant 30. The regenerated air distribution member 90 includes a discharge part through which air sucked through the suction part is discharged, and the discharge part communicates with regenerated air inlets 122, 124, 142, 144, 162 and 164 formed in each of the heat exchange plates 120, 140, and 160 described later. Is formed.

The inflow portion of the heat exchanger plate in this embodiment is formed in two directions, and two discharge portions are formed in the regenerated air distribution member 90. One discharge portion communicates with the inflow portions 122, 142 and 162 through which the regeneration air flows in the horizontal direction, and the other discharge portion communicates with the inflow portions 124, 144 and 164 through which the regeneration air flows in the vertical direction.

The condensation heat exchanger 100 exchanges the air passing through the regenerated air distribution member 90 with the indoor air. That is, the regenerated air adsorbed with moisture while passing through the regeneration region of the dehumidification rotor 30 is condensed using indoor air, and the regenerated air from which moisture is removed is discharged to the regeneration fan 50 through the exhaust duct 80. And the condensate is discharged to the drain pan (14).

On the other hand, the condensation heat exchanger 100 in this embodiment includes a plurality of heat exchange plates (120, 140, 160). Each heat exchange plate 120, 140, 160 includes an inlet 122, 124, a regenerated air passage 126, an indoor air passage 128, and an outlet 134.

The above configurations formed on each heat exchanger plate 120, 140, and 160 are common, and will be described below based on one heat exchanger plate 120, and differences in the respective heat exchanger plates 120, 140, and 160 will be described separately.

3 is a front perspective view of a heat exchanger plate according to an embodiment of the present invention, FIG. 4 is a rear perspective view of the heat exchanger plate of FIG. 3, FIG. 5 is a front view of the heat exchanger plate of FIG. 3, and FIG. 6 is taken along line XX of FIG. 3. It is sectional drawing which cut | disconnected the heat exchanger plate of a present Example.

3 to 6, the inflow parts 122 and 124 serve as an inlet for regenerated air discharged through the discharge part of the regenerated air distribution member 90. Therefore, it is installed in communication with the discharge portion of the regeneration air distribution member 90.

The number and positions of the inflow parts 122 and 124 may be variously located according to the flow of the regenerated air flowing therein. In the present embodiment, two inlets 122 and 124 are installed at the upper circumference of the heat exchange plate 120.

The two inlets 122 and 124 may be positioned in various directions depending on the positions of the outlets 134 and the shapes and positions of the plurality of regeneration sharing passages 126. In the present embodiment, one inlet 122 is formed in the horizontal direction at the periphery of the heat exchange plate 120 to introduce regeneration air in the horizontal direction. And the other inlet 124 is formed in the vertical direction of the heat exchange plate 120 to flow the regeneration air in the vertical direction.

The discharge part 134 is an outlet through which the regenerated air exchanged with the indoor air is discharged while passing through the heat exchange plate 120. The discharge part 134 may be formed at various positions of the heat exchange plate 120.

The discharge part in this embodiment is formed on one side of the lower peripheral portion of the heat exchange plate (120). Therefore, the flow distance of the regenerated air introduced through the upper inlets 122 and 124 may be increased to increase the heat exchange time and area.

And the discharge part 134 has the advantage that the size of the overall dehumidifier can be reduced when located on one side of the left, right side of the lower circumference.

The regeneration air passage 126 is a passage through which regeneration air positioned between the inlets 122 and 124 and the discharge unit 134 passes. The regenerated air exchanges heat with the indoor air while passing through the regenerated air flow path 126. The regeneration air passage 126 in this embodiment is formed of a plurality of pipes formed in the vertical direction of the heat exchange plate. That is, the air introduced through the inlets 122 and 124 formed in the upper part is formed in the vertical direction so that the air can be discharged well to the outlet part 134 in the lower part. And the indoor air flow path 128 to be described later is formed between the plurality of pipes, respectively.

On the other hand, as described above, when the discharge part 134 is located at the lower left and right sides of the heat exchange plate 120, the distance between the plurality of inlets 122 and 124 and the discharge part 134 is different. As a result, the distances through which the air passing through each of the inlets 122 and 124 flow in the heat exchange plate 120 are different. Therefore, an imbalance in flow in the heat exchange plate of the regenerated air introduced into the heat exchange plate 120 may occur.

Hereinafter, the dispersion unit 130 and the regeneration air flow path 126 in this embodiment to solve the imbalance of the flow will be described.

The dispersion unit 130 is formed between the inlet 122 and the outlet 134 close to the outlet 134. Dispersion unit 130 serves to slow down the flow rate of the regeneration air while dispersing the flow of air. In more detail, a baffle of various forms is formed in a space (hereinafter, referred to as a “dispersion space”) between the inlet 122 and the outlet 134 where the distance from the outlet 134 is relatively close. That is, the dispersion unit 130 in the present embodiment includes a plurality of circular baffles formed in the dispersion space.

In addition, an indoor air flow path 130a through which indoor air may pass may be formed in each circular baffle. Therefore, the indoor air can flow through the indoor air flow path 130a located in the dispersion zone, thereby condensing the regenerated air passing through the dispersion zone.

On the other hand, the dispersion unit 130 may be located on the inlet 124 side in the space between the inlet 124 and the discharge unit 134. Therefore, it may also serve to slow down the speed of the regenerated air introduced through the inlet 124 and to diversify the flow of the regenerated air introduced through the one inlet 124. That is, it is possible to smoothly flow the regenerated air in the heat exchange plate 120 by dispersing the regenerated air passed through one inlet 124 to each of the plurality of regenerated air flow paths 126.

Therefore, the dispersing unit 130 in the present embodiment is located on the inlet 124 side close to the discharge unit 134, but on the inlet 122, 124 side irrespective of the distance to the discharge unit 134. When located, it is possible to obtain an effect of dispersing air introduced through each inlet 122 and 124 into each of the plurality of regeneration air passages 126.

On the other hand, the regeneration air flow path 126 located between the inlet portion and the discharge portion 134 close to the discharge portion 134 may be positioned at an angle in a vertical direction. A portion of the up and down flow path may be bent and formed. Therefore, it is possible to maintain the balance of the discharge time with the regeneration air introduced from the inlet 124, the distance from the outlet 134 is relatively far. In addition, by reducing the speed of the regeneration air passing through the regeneration air passage 126 it is possible to ensure a sufficient heat exchange time with the indoor air.

In detail, in the present exemplary embodiment, the regeneration air flow path 126a disposed below the dispersion area is inclined toward the discharge part 134. Therefore, the indoor air flow path 128a located between the inclined regeneration air flow path 126a is also inclined. As a result, the distance that the regenerated air travels is longer than that of the case where the vertical air is positioned, thereby increasing the time until the regenerated air is discharged.

In addition, the regeneration air passage 126b in which a part of the up and down flow path is bent serves to reduce the speed of the regeneration air by bending the flow of the regeneration air having the downward flow in the vertical direction. In detail, in the present exemplary embodiment, the bent regeneration air passage 126b is positioned below the inclined regeneration air passage 126a.

The bent regenerated air flow path 126b may be bent in various directions, but is bent and formed in the indoor air flow direction in this embodiment. The cross sectional area of the regeneration air passage 126b after the bending may be larger than the cross sectional area of the regeneration air passage 126 before the bending. As a result, the heat exchange area of the indoor air passage 128b located between the regenerated air passage 126b after bending is located between the inclined regeneration air passage 126a and the inclined regeneration air passage 126a. It is formed wider than the indoor air flow path (128a).

In addition, the cross-sectional areas of the plurality of regenerative air flow passages 126 formed in the vertical direction may be made smaller toward the discharge portion 134. That is, a small amount of regeneration air flows in the regeneration air passage 126 close to the discharge unit 134, and a relatively large amount of regeneration air flows in the regeneration air passage 126 far from the discharge unit 134. Will be Therefore, the discharge portion 134 is formed on one side of the heat exchange plate 120 can prevent the imbalance of the regeneration air flow that may occur.

On the other hand, between the entire regeneration air flow path 126 of the heat exchange plate 120 may be formed baffle flow path 127 in the left, right direction to reduce the flow rate of the regeneration air flowing. Therefore, the speed of the regeneration air flowing through the regeneration air flow path 126 is increased to increase the time for regeneration air to exchange heat with the indoor air.

The indoor air passage 128 is formed to allow indoor air to pass between the plurality of regenerated air passages 126 of the heat exchange plate 120. Therefore, regenerated air flowing through the regenerated air flow path 126 exchanges heat with indoor air. The regenerated air adsorbed while passing through the regeneration zone of the desiccant 130 is condensed using indoor air to remove the regenerated air.

The indoor air passage 128 has an opening formed in the vertical direction between the regeneration air passage 126. As described above, the indoor air flow path 126a located between the inclined regeneration air flow paths 126a is formed to be inclined at an angle in the vertical direction, and has a larger area for heat exchange with the regeneration air than other indoor air flow paths 126. do.

As described above, the dispersion unit 130 may be formed to have an opening to further include an indoor air flow path 130a.

On the other hand, the lower portion of the heat exchange plate 120 is formed with a discharge hole 132 through which the condensed water condensed in the regeneration air is discharged. The condensed water discharged through the discharge hole 132 is accommodated in the bucket 10 via the drain pan 14.

The condensation heat exchanger 100 in this embodiment includes a plurality of heat exchange plates 120, 140, 160. Hereinafter, the difference between the heat exchanger plates 140 and 160 other than the heat exchanger plate 120 and the fastening structure of the plurality of heat exchanger plates will be described in detail.

FIG. 7 is an exploded perspective view of the condensation heat exchanger and the exhaust duct of the embodiment of the present invention, FIG. 8 is a rear perspective view of the condensation heat exchanger of FIG. 7, and FIG.

7 to 9, the condensation heat exchanger 100 includes a plurality of heat exchange plates 120, 140, and 160, and the plurality of heat exchange plates 120, 140, and 160 are arranged side by side along the indoor air direction.

As described above, the structure and shape of the flow path of the plurality of heat exchange plates (120, 140, 160) is generally formed similarly. However, the heat exchanger plates 140 and 160 having different bent regeneration air flow paths 126a of the first heat exchanger plate 120 are formed differently. In the second and third heat exchange plates 140 and 160, both the front and rear surfaces of the regeneration air flow path 126 are bent, but in the case of the first heat exchange plate 120, only the rear surface of the regeneration air flow path 126 is bent and formed. As a result, the difference in cross-sectional area of the regeneration air passage 126 before and after bending of the first heat exchanger plate 120 is greater than that of the other heat exchanger plates 140 and 160.

On the other hand, the plurality of heat exchange plates (120, 140, 160) may be formed at a predetermined interval apart. Therefore, it is possible to increase the regeneration air and the heat exchange area by diversifying the flow of the indoor air flowing through each of the heat exchange plates (120, 140, 160).

However, in this embodiment, each heat exchange plate (120, 140, 160) is coupled while contacting each of the front and rear. Each heat exchange plate 120, 140, 160 may be bonded with an adhesive, or may be combined with a separate fastening member.

Specifically, the fixing protrusions protrude outward from the periphery of each of the heat exchange plates 120, 140, and 160, and each heat exchange plate may be fixed using a fastening member having a groove in which the fixing protrusions are accommodated. In addition, a plurality of fixing protrusions and fastening members may be installed at circumferences of the heat exchange plates 120, 140, and 160.

In addition, the fastening members 121 and 161 are integrally formed on the plurality of heat exchange plates 120, 140 and 160, and a groove is formed in the fastening member. Specifically, the fastening member 121 is integrally formed on the first heat exchange plate 120 in the indoor air direction, and the groove 121a is formed in the fastening member 121. In addition, protrusions 145 and 165 coupled to the grooves 121a are formed in the two heat exchange plates 140 and 160 positioned on the rear surface of the first heat exchange plate 120. And the fastening member 121 is formed to be bent around the heat exchange plate 120, the remaining heat exchange plate (140, 160) is coupled to the first heat exchange plate 120 and then bent to the protrusions (145,165).

A plurality of fastening members 121 and 161 may be formed at the periphery of each of the heat exchange plates 120, 140 and 160. Specifically, in the present embodiment, the fastening member 161 is also formed in the heat exchange plate 160 located last in the indoor air inflow direction. And the remaining heat exchange plates (120, 140) are formed with projections (123, 143) for coupling with the fastening member 161, respectively. Coupling of the fastening members 161 and the protrusions 123 and 143 is as described above.

The exhaust duct 80 serves to discharge the regenerated air after condensation in the condensation heat exchanger 100. That is, one end is in communication with the discharge parts 134, 154, and 174 of each heat exchange plate 120, 140, and 160, and the multi-stage is in communication with the opening 43a of the rotor frame 43.

The plurality of discharge parts 134, 154, 174 protrude from the periphery of each heat exchange plate 120, 140, 160, and the exhaust duct 80 is fitted with the plurality of discharge parts 134, 154, 174. Therefore, the exhaust duct 80 serves to fix the coupling between the plurality of heat exchange plates (120, 140, 160).

In addition, protrusions and grooves are formed in the exhaust duct 80 to be fitted with the plurality of discharge parts 134, 154, and 174, respectively, to serve to firmly fit the fittings. In the present embodiment, the projections 136, 156, 176 and the grooves 138, 158, 178 are formed in the plurality of heat exchange plates 120, 140, 160, respectively. The protrusions 136, 156, 176 and the grooves 138, 158, 178 formed at positions corresponding to each other are coupled to each other. In the exhaust duct 80, grooves 82 corresponding to the projections 136 and projections (not shown) corresponding to the grooves 178 are formed at positions corresponding to each other.

Looking at the condensation process and the indoor air dehumidification process of the regeneration air of the present invention dehumidifier configured as described above are as follows.

First, the regeneration air circulates through the regeneration path by the rotation of the regeneration fan 50. That is, the regenerated air passing through the regeneration fan 50 is heated by the regenerated air heating member 60 to increase the temperature. The high temperature regenerated air regenerates the regenerated area of the dehumidifying rotor 30 and flows into the condensation heat exchanger 100 through the regenerated air distribution member 90.

The regenerated air introduced into the condensation heat exchanger 100 exchanges heat with indoor air while flowing from the top to the bottom of each heat exchange plate 120, 140, 160. In the heat exchange process, moisture in the regeneration air is condensed, and the condensed water is discharged from the condensation heat exchanger 100 and received in the bucket 10 via the drain pan 14.

The condensed regeneration air flows back into the regeneration fan 50 through the opening 43a of the rotor frame 43 through the exhaust duct 80. That is, the regenerated air circulates in the main body along the above cycle.

On the other hand, the indoor air is sucked through the air inlet of the main body to exchange heat with the regeneration air flowing in the regeneration air passage while passing through the indoor air passage of the condensation heat exchanger (100). The indoor air passing through the condensation heat exchanger (100) passes through the dehumidifying area of the desiccant (35), whereby moisture is adsorbed and dehumidified. The indoor air absorbed by the moisture passes through the blower fan 20 and is discharged back to the room through the air discharge part of the main body.
