Description

Dehumidifying module and dehumidifier including the same

[0001] The present invention relates to a dehumidifying module and a dehumidifier including the same.

[0002] A dehumidifier is a type of home appliance that lowers the humidity in a desired space by sucking in air from a desired space, removing the moisture contained in the air, and discharging the dehumidified air into the desired space.

[0003] Conventional dehumidifiers remove moisture by sucking in air from a desired space and passing it through a heat exchanger consisting of a condenser and an evaporator, thereby exchanging heat between the refrigerant flowing through the condenser and the air passing through the evaporator.

[0004] The evaporator absorbs heat from the surrounding air by evaporating the liquid refrigerant, and the condenser releases heat by condensing the gaseous refrigerant, thereby transferring the heat to the surrounding air. In other words, the air passing through the heat exchanger exchanges heat with the refrigerant as it passes through the evaporator, thereby lowering its humidity. As the air with reduced humidity passes through the condenser, it exchanges heat with the refrigerant, thereby undergoing a drying process.

[0005] The dried air passing through the above heat exchanger is discharged to the desired space, thereby lowering the humidity in the air of the desired space.

[0006] These conventional dehumidifiers had the problem of causing discomfort to the user due to the temperature of the discharged air rising.

[0007] The purpose of the present invention is to provide a dehumidification module using a membrane (hollow fiber membrane) to increase the contact surface area between air and a dehumidifying member.

[0008] The purpose of the present invention is to provide a dehumidification module that can ensure smooth air flow and prevent large pressure loss by fixing both sides of a plurality of hollow fiber membranes using potting and configuring a dehumidification member so that air passes through the plurality of hollow fiber membranes.

[0009] The purpose of the present invention is to provide a dehumidifying module in which a cap member is provided on both sides of a dehumidifying member to facilitate a potting process.

[0011] The purpose of the present invention is to provide a dehumidifying module in which the support capacity for a dehumidifying member can be improved by providing a support connecting first and second caps provided on both sides of the dehumidifying module.

[0096] Referring to FIGS. 1 to 7, a dehumidifying module (300) according to a first embodiment of the present invention may be configured to contact humid air, separate moisture from the humid air, discharge the separated moisture in a first direction, and discharge the dehumidified air in a second direction.

[0097] The first direction and the second direction may be different directions. For example, the first direction and the second direction may be orthogonal to each other (see Fig. 18). With such a configuration, moisture separation performance can be improved.

[0098] The above dehumidification module (300) may include a dehumidification member (320) capable of selectively separating moisture from the inhaled air.

[0099] The above dehumidifying member (320) may include a membrane.

[0100] The above-mentioned dehumidifying member (320) may include a polymer membrane fiber (321, see FIG. 10) having a hollow fiber structure with excellent selectivity for moisture. The polymer membrane fiber (321) may be cut to a predetermined length and used. The polymer membrane fiber (321) may be referred to as a "hollow fiber membrane."

[0101] The above polymer film fiber (321) may be configured to have a diameter of, for example, about 400 to 420 μm.

[0102] The above polymer membrane fiber (321) may be composed of, for example, polysulfone or polypropylene material.

[0103] A coating layer may be provided on the surface of the polymer film fiber (321) to increase the selectivity of moisture in the air. The coating layer may be composed of polyamide.

[0104] The above polymer membrane fiber (321) can be provided in multiple strands.

[0105] The above dehumidifying member (320) may further include a packing member (323, see FIG. 10) surrounding the plurality of polymer film fibers (321) to fix (maintain the shape) the polymer film fibers (321) composed of the plurality of strands.

[0106] The plurality of polymer film fibers (321) can be formed into a bundle by the above packing member (323). The bundle of dehumidifying members (320) can form a single dehumidifying member.

[0107] The above-mentioned packing member (323) is composed of a resin material, has strong water resistance, and can suppress bacterial growth and mold growth. In addition, the packing member (323) can perform the function of protecting the dehumidifying member (321) by blocking large dust particles in the air. For example, the packing member (323) can be composed of a polypropylene material.

[0108] The above packing member (323) may be configured to include a number of small holes to allow moist air to pass through. For example, the packing member (323) may be configured as a mesh type.

[0109] The above dehumidifying module (300) may be configured to provide a plurality of dehumidifying members (320). For example, as illustrated in FIG. 1, the dehumidifying module (300) may be configured to have approximately 10 dehumidifying members (320) arranged in parallel.

[0110] The direction in which the above-mentioned plurality of dehumidifying members (320) are arranged, i.e., the horizontal direction in the drawing, can form a direction perpendicular to the direction in which moist air is introduced.

[0111] The above dehumidifying module (300) may further include a fixing member (330a, 330b) configured by a potting method to fix the dehumidifying member (320). The fixing member (330a, 330b) may be configured by being filled and solidified in a liquid form inside the first cap (340) to fix the positions of a plurality of dehumidifying members (320).

[0112] For example, the above-mentioned fixed part (330a, 330b) may be made of urethane or epoxy material.

[0113] The above fixing part (330a, 330b) may include a first fixing part (330a) for fixing one end of the dehumidifying member (320) and a second fixing part (330b) for fixing the other end.

[0114] The above first cap (340) may be called a “potting cap.” The above first cap (340) may include an upper cap (340a) provided on the upper side of the dehumidifying module (300) and a lower cap (340b) provided on the lower side.

[0115] The first fixing member (330a) may be positioned inside the upper cap (340a). The second fixing member (330b) may be positioned inside the lower cap (340b).

[0116] In order to allow the above-described fixing portions (330a, 330b) to be placed, a potting space (343) may be formed inside the first cap (340a, 340b). The potting space (343) provided in the upper cap (340a) may be referred to as a "first potting space", and the potting space (343) provided in the lower cap (340b) may be referred to as a "second potting space".

[0117] The end (320a) of the dehumidifying member (320) fixed by the above-mentioned fixing member (330a, 330b) can be exposed to the outside of the above-mentioned fixing member (330a, 330b).

[0118] The first cap (340a, 340b) may include a first part (341) and a second part (342). The first part (341) provides a coupling surface that is coupled to the second cap (350a, 350b), and may be fastened to the second cap (350a, 350b) by a predetermined fastening member.

[0119] The second part (342) may extend stepwise from the first part (341). The internal cross-sectional area of ​​the second part (342) may be formed to be smaller than the internal cross-sectional area of ​​the first part (341). The potting space (343) may be formed inside the second part (342).

[0120] The above dehumidifying module (300) may further include a second cap (350) covering the first caps (340a, 340b). The second cap (350) may be referred to as an "end cap." The second cap (350) may include a first end cap (350a) covering the upper cap (340a) and a second end cap (350b) covering the lower cap (340b).

[0121] The second cap (350a, 350b) may include a first part (351) and a second part (352). The first part (351) provides a coupling surface that is coupled to the first cap (340a, 340b), and may be fastened to the first cap (340a, 340b) by a predetermined fastening member.

[0122] The second cap (350a, 350b) may be formed with one or more fastening portions (357). The first cap (340a, 340b) may be formed with another fastening portion (347, see FIG. 8) corresponding to the fastening portion (357). The fastening portion (347) may be referred to as a “first fastening portion,” and the fastening portion (357) may be referred to as a “second fastening portion.”

[0123] The second part (352) may extend stepwise from the first part (351). The internal cross-sectional area of ​​the second part (352) may be formed to be smaller than the internal cross-sectional area of ​​the first part (351). An air flow space may be formed inside the second part (352).

[0124] The first end cap (350a) may be provided with a connection port (354) through which at least a portion of the air discharged from the fan (150) is introduced. For example, the connection port (354) may be formed on a side surface of the second part (352).

[0125] When the upper cap (340a) and the first end cap (350a) are called “upper caps” and the lower cap (340a) and the second end cap (350b) are called “lower caps”, the direction in which the upper cap, the dehumidifying member (320) and the lower cap are arranged, i.e., the up-down direction based on FIG. 1, can be perpendicular to the direction in which moist air is introduced, i.e., the front-back direction.

[0126] In addition, the direction in which the upper cap, the dehumidifying member (320) and the lower cap are arranged can be perpendicular to the left and right direction in which the plurality of dehumidifying members (320) are arranged.

[0127] Air that has passed through the valve device (170, see Fig. 13) and supply pipe (172, see Fig. 13) provided in the dehumidifier (10, see Fig. 11) can flow into the interior of the first end cap (350a) through the connection port (354).

[0128] The above dehumidifying module (300) may further include a distribution plate (356) provided on the inside of the first end cap (350a). The distribution plate (356) may be supported at an end of the upper cap (340a) and shielded by the first end cap (350a).

[0129] The above connection port (354) can be connected to the space (distribution space) between the distribution plate (356) and the upper surface of the first end cap (350a). Accordingly, air can flow into the distribution space through the connection port (354) and toward the distribution plate (356).

[0130] A plurality of distribution holes (356a) may be formed in the above distribution plate (356). Air may flow toward the end (320a) of the dehumidifying member (320) through the plurality of distribution holes (356a) and may flow toward the inner peripheral surface forming the hollow portion of the dehumidifying member (320), i.e., the hollow portion of the polymer membrane fiber (321).

[0131] Due to the pressure difference between the inside and outside of the dehumidifying member (320), when water vapor passes through the dehumidifying member (320), a phenomenon of accumulation on the inner wall of the dehumidifying member (320) may occur. Such water vapor may deteriorate the dehumidifying performance of the dehumidifying member (320).

[0132] In order to solve this problem, at least a portion of the air discharged from the fan (150, see FIG. 12) is bypassed to pass through the distribution hole (356a) and supplied to the dehumidifying member (320), thereby removing the water vapor accumulated on the inner wall.

[0133] A recessed portion (353) may be formed in the second cap (350a, 350b). The recessed portion (353) may form a space between the end portion (320a) of the dehumidifying member (320) and the end surface of the second cap (350a, 350b).

[0134] The recessed portion (353) of the first end cap (350a) forms a space between the distribution plate (356) and the upper surface of the first end cap (350a), thereby forming a path for air flowing into the distribution hole (356a).

[0135] The recessed portion (353) of the second end cap (350b) can form a path through which moisture (water vapor) separated from the dehumidifying member (320) flows to the cap hole (355).

[0136] The above dehumidifying module (300) may further include a support (314) to reinforce the one-way supporting force of the dehumidifying member (320). For example, the support (314) may reinforce the vertical supporting force of the dehumidifying member (320).

[0137] Since the above dehumidifying member (320) is formed to be relatively long in the vertical direction, the support (314) can provide support in the vertical direction.

[0138] The support (314) may extend between the upper cap (340a) and the lower cap (340b). One end of the support (314) may be connected to the upper cap (340a), and the other end may be connected to the lower cap (340b). For example, the support (314) may have a bar shape.

[0139] The above support (314) is provided in multiple numbers, and the multiple supports (314) may include a first support (314a) provided on one side of the upper cap (340a) and the lower cap (340b) and a second support (314b) provided on the other side.

[0140] The first support member (314a) may be positioned at a position spaced apart from the first side of the plurality of dehumidifying members (320). The second support member (314b) may be positioned at a position spaced apart from the second side of the plurality of dehumidifying members (320).

[0141] The above-mentioned plurality of dehumidifying members (320) may be positioned between the first support member (314a) and the second support member (314b).

[0142] A space (319) may be formed between the first support (314a) and the plurality of dehumidifying members (320), or between the second support (314b) and the plurality of dehumidifying members (320).

[0143] The above space (319) may function as a space through which humid air leaks without passing through the dehumidifying member (320) when passing through the dehumidifying module. Therefore, in order to eliminate this leaking space, the dehumidifying module (300) may include a housing (310).

[0144] The above housing (310) can function as a member that blocks the open space around the dehumidifying members (320) to prevent air from leaking (losing) into the space around the plurality of dehumidifying members (320) and the support (314).

[0145] In detail, the dehumidifying module (300) may include a housing (310) arranged to surround at least a portion of the dehumidifying member (320). The housing (310) may include a first part (310a) that covers both sides of the plurality of dehumidifying members (320).

[0146] The above first parts (310a) are provided on one side and the other side of the plurality of dehumidifying members (320), respectively, and the plurality of first parts (310a) can be arranged to face each other.

[0147] An installation space (310b) in which a plurality of dehumidifying members (320) are installed can be formed between the plurality of first parts (310a).

[0148] In the first part (310a), a joining hole (311) into which the support (314) is joined or inserted can be formed. The first part (310a) can prevent air leakage by shielding the front and rear ends of the support (314).

[0149] The housing (310) may further include a shielding wall (312) provided on the inner surface of the first part (310a) and shielding the space between the support (314) and the plurality of dehumidifying members (320).

[0150] The above shielding wall (312) can protrude from the inner surface of the first part (310a) toward the plurality of dehumidifying members (320).

[0151] The above shielding walls (312) are provided in multiple numbers and can be provided on each inner surface of the multiple first parts (310a).

[0152] One of the plurality of shielding walls (312) may be configured to shield a space (319) formed between the first support (314a) and the plurality of dehumidifying members (320). Another of the plurality of shielding walls (312) may be configured to shield a space (319) formed between the second support (314b) and the plurality of dehumidifying members (320).

[0153] The above shielding wall (312) may include a first shielding wall (312a) and a second shielding wall (312b) spaced apart in the direction in which the wet air flows.

[0154] The first and second shielding walls (312a, 312b) may be provided on both sides of the coupling hole (311). The first shielding wall (312a) may be provided on the front end side of the coupling hole (311), and the second shielding wall (312b) may be provided on the rear end side of the coupling hole (311).

[0155] The housing (310) may include a second part that covers at least a portion of the upper and lower sides of the plurality of dehumidifying members (320). The second part may include a first part that covers a portion of the upper cap (340a) and a second part (315b) that covers a portion of the lower cap (340b).

[0156] The first part may be provided on the leading and trailing sides of the upper cap (340a), respectively. The second part (315b) may be provided on the leading and trailing sides of the lower cap (340b), respectively.

[0157] Among the first parts, the part provided on the tip side of the upper cap (340a) may include a water supply duct (315a) for supplying water to the dehumidifying member (320).

[0158] Water supplied from a water pump (180, see Fig. 15) can flow through the above water supply duct (315a). A water supply hole (316) for supplying water toward the dehumidifying member (320) can be formed on the bottom surface of the above water supply duct (315a).

[0159] The above water supply holes (316) are formed in multiple numbers, and the multiple water supply holes (316) can be arranged in the direction in which the multiple dehumidifying members (320) are arranged, that is, in the left and right directions based on FIG. 6.

[0160] The above water supply hole (316) may be located at the upper front side of the dehumidifying member (320). Even if water is sprayed toward the front of the dehumidifying member (320) through the water supply hole (316), the water may come into contact with the dehumidifying member (320) due to the suction force of the fan (150).

[0161] Water supply through the above water supply hole (316) can be intermittent.

[0162] The housing (310) may include a water supply port (317) connected to a water supply connection pipe (185, see FIG. 15), i.e., a second connection pipe (185b, see FIG. 15). The water supply port (317) may be connected to the water supply duct (315a). For example, the water supply port (317) may pass through the housing (310) and be connected to a side surface of the water supply duct (315a).

[0163] Water pumped from the above water pump (180) flows into the water supply port (317) through the second connecting pipe (185b) and can flow into the inside of the water supply duct (315a).

[0164] When the dehumidifier (10) is operated in an environment with very low absolute humidity, the moisture separation performance of the dehumidifying member (320) may be weakened. Therefore, in order to improve the moisture separation performance, water may be supplied to the dehumidifying member (320) (improving the wettability of the dehumidifying member).

[0165] To form such a water supply path, the dehumidifier (10) can provide a water pump (180), a connecting pipe (185), and a water supply duct (315a).

[0166] The above dehumidifying module (300) may further include a sealer (371, 372) for sealing the space between the first cap (340a, 340b) and the second cap (350a, 350b).

[0167] The above sealer (371, 372) may include a first sealer (371) provided between the upper cap (340a) and the first end cap (350a). The first sealer (371) may be in contact with the upper cap (340a) and the first end cap (350a).

[0168] The above sealer (371, 372) may include a second sealer (372) provided between the lower cap (340b) and the second end cap (350b). The second sealer (372) may be in contact with the lower cap (340b) and the second end cap (350b).

[0169] FIG. 8 is a drawing showing a dehumidifying member fixed by a fixing member inside a first cap according to a first embodiment of the present invention, FIG. 9 is an enlarged drawing of part A of FIG. 8, and FIG. 10 is a drawing showing the configuration of a dehumidifying member according to a first embodiment of the present invention.

[0170] Referring to FIGS. 8 to 10, a first cap (340a, 340b) according to the first embodiment of the present invention is provided with a fixing part (330a, 330b), and the fixing part (330a, 330b) can support the dehumidifying member (320) to the dehumidifying module (300).

[0171] Figure 8 shows the configuration of the upper cap (340a), and the description regarding the configuration of the upper cap (340a) can be equally applied to the lower cap (340b).

[0172] The upper cap (340a) may include a first part (341) in which a fastening portion (347) for coupling with the second cap (350a, 350b) is formed.

[0173] A potting space (343) in which the first fixing part (330a) is disposed may be formed inside the second part (342). When at least a portion of the dehumidifying member (320) is disposed in the potting space (343), the potting space (343) may be filled with a potting solution, and when the potting solution hardens, the first fixing part (330a) may be formed.

[0174] The above dehumidifying member (320) may include a plurality of polymer membrane fibers (321).

[0175] The above-mentioned plurality of polymer film fibers (321) are surrounded by a packing member (323), and one dehumidifying member (320) can be formed into a bundle by being bound by a plurality of polymer film fibers (321) and the packing member (323).

[0176] The above polymer film fiber (321) has a hollow cylindrical shape and can be configured to have a small diameter but a relatively large length.

[0177] In detail, the polymer film fiber (321) may include an outer peripheral surface (321a) and an inner peripheral surface (321b) with which moist air comes into contact. The inner peripheral surface (321b) may define a hollow portion (321c) to form a flow path through which separated moisture flows.

[0178] When the above-mentioned moist air comes into contact with the outer peripheral surface (321a), moisture contained in the moist air is adsorbed on the surface of the outer peripheral surface (321a), and the adsorbed moisture can be selectively separated from the air by diffusing and then being desorbed from the surface.

[0179] At this time, the vacuum pump (230, see FIG. 12) is driven, and by the driving of the vacuum pump (230), a pressure difference between the outside and inside of the dehumidifying member (320) is generated, and a negative pressure lower than the external pressure can be formed inside the dehumidifying member (320). By this pressure difference, adsorption and desorption of the moisture can occur.

[0180] FIG. 11 is a perspective view showing the appearance of a dehumidifier according to a first embodiment of the present invention, FIG. 12 is a rear perspective view showing the configuration of a dehumidifier according to a first embodiment of the present invention, FIG. 13 is a front perspective view showing the configuration of a dehumidifier according to a first embodiment of the present invention, FIG. 14 is a left-side perspective view showing the configuration of a dehumidifier according to a first embodiment of the present invention, and FIG. 15 is a right-side perspective view showing the configuration of a dehumidifier according to a first embodiment of the present invention.

[0181] Referring to FIGS. 11 to 15, the dehumidifier (10) according to the first embodiment of the present invention may have a three-dimensional shape in which the height in the vertical direction is greater than the width in the front-back direction.

[0182] Define the direction. In Fig. 11, the surface where the first suction part (110a) is formed is defined as the front, in Fig. 2, the surface where the second suction part (115a) is formed is defined as the rear, and in Fig. 3, the surface where the discharge part (106) is formed is defined as the upper surface.

[0183] The above dehumidifier (10) may include a main body (100) forming an exterior. The main body (100) may accommodate a number of components for sucking in air, removing moisture from the sucked air, and discharging the dehumidified air.

[0184] The above body (100) may include a front portion (101), a rear portion (102), a first side portion (103), a second side portion (104), an upper portion (105), and a bottom portion. The bottom portion may be defined by a base (210).

[0185] The front portion (101) may include a first suction portion (110a) for sucking air. A first suction grill (110) may be provided in the first suction portion (110a). Air in an indoor space to be dehumidified may be sucked in through the first suction portion (110a). The air flow sucked in through the first suction portion (110a) may be referred to as "first suction flow (first flow)" or "main flow."

[0186] The rear part (102) can be arranged to face the front part (101).

[0187] The rear portion (102) may include a second suction portion (115a) for sucking air. A second suction grill (115) may be provided in the second suction portion (115a). Through the second suction portion (115a), air in the indoor space to be introduced into the heat exchanger (160) may be sucked in. The air flow sucked in the second suction portion (115a) may be referred to as "second suction flow (second flow)" or "sub flow."

[0188] The above first side portion (103) connects one side of the front portion (101) and the rear portion (102) and can form one side of the dehumidifier.

[0189] The second side portion (104) may connect the other side of the rear portion (102) to the front portion (101) and form the other side of the dehumidifier. The second side portion (104) may be arranged to face the first side portion (103).

[0190] The upper surface (105) may form a discharge portion (106) that discharges air from the dehumidifier (10). The discharge portion (106) may be provided with a discharge vane (107) that controls the opening or closing of the discharge portion (106).

[0191] The upper surface (105) may include a display unit (108) that outputs operating information of the dehumidifier (10). The display unit (108) may be provided with an input unit for inputting an operating command.

[0192] The display portion (108) may be positioned adjacent to the front portion (101) of the upper surface portion (105), and the discharge portion (106) may be formed adjacent to the rear portion (102) of the upper surface portion (105).

[0193] When a user approaches the dehumidifier (10), the user can approach in a direction closer to the front part (101) to easily operate the display part (108). In addition, since the tank (250, 260) provided in the dehumidifier (10) is provided to be detachable from the front part (101), the user's accessibility and convenience of operation can be improved.

[0194] A tank (250, 260) for storing water may be provided in a mountable or detachable manner at the bottom of the above dehumidifier (10).

[0195] The above tank (250, 260) may include a drain tank (250) in which condensate is stored after water vapor separated from the dehumidification module (300) is condensed in the heat exchanger (160). The drain tank (250) may include a first handle (258) that a user can grip.

[0196] The above tank (250, 260) may include a water supply tank (260) that stores water to be supplied to the dehumidification module (300) in order to improve the moisture separation characteristics in the dehumidification module (300). The water supply tank (260) may include a second handle (268) that a user can hold.

[0197] The dehumidifier (10) may further include an auxiliary display unit (280) that provides information regarding whether the tank (250, 260) is installed. The auxiliary display unit (280) may be provided at the front of the first partition wall (121). The auxiliary display unit (280) may also provide a notification regarding the emptying or supply of water in the tank (250, 260) based on the water level of the tank (250, 260).

[0198] When the above tank (250, 260) is mounted, the auxiliary display unit (280) may be provided at a location shielded by the tank (250, 260). For example, the tank (250, 260) is made of a transparent material, so that even when the tank (250, 260) is mounted, information output from the auxiliary display unit (280) can be confirmed from the outside.

[0199] The lower surface of the dehumidifier (10) is provided with a base (210), and the base (210) can function as a support plate forming a machine room of the dehumidifier (10). A plurality of legs (109) placed on the ground can be provided on the lower side of the base (210).

[0200] The above dehumidifier (10) may include a first part (A) forming an upper portion and a second part (B) forming a lower portion. The first part (A) may be referred to as an “upper part” and the second part (B) may be referred to as a “lower part.”

[0201] The interior of the main body (100) may include a first partition wall (121) that divides a first space (upper space) in which components constituting the first part (A) are installed, and a second space (lower space) in which components constituting the second part (B) are installed.

[0202] The components constituting the above first part (A) may include a dehumidification module (300), a fan (150), and a heat exchanger (160).

[0203] The components constituting the first part (A) may further include a valve device (170) and a supply pipe (172) that supply at least a portion of the air discharged from the fan (150) to the dehumidifying module (300).

[0204] The components constituting the second part (B) may include a vacuum pump (230) and a tank (250, 260). The tank (250, 260) may include a drain tank (250) and a water supply tank (260).

[0205] The vacuum pump (230) may be aligned to the lower side of the fan (150) and the heat exchanger (160), and the tank (250, 260) may be aligned to the lower side of the dehumidification module (300).

[0206] The components constituting the first part (A) or the second part (B) may include a water pump (180) and a water supply connection pipe (185) connected to the water supply tank (260) to transfer water from the water supply tank (260) to the dehumidification module (300).

[0207] The above dehumidification module (300) can be installed on the upper surface of the first bulkhead (121).

[0208] The dehumidifying module (300) may be placed inside the first suction portion (110a). Accordingly, the dehumidifying module (300) may be placed so that air introduced into the first part (A) through the first suction portion (110a) passes therethrough.

[0209] The above first part (A) may further include a second partition wall (123) that divides the installation space of the dehumidification module (300) and the installation space of the fan (150). The second partition wall (123) may separate the first suction flow passing through the dehumidification module (300) from the first suction part (110a) and the second suction flow passing through the heat exchanger (160) from the second suction part (115a).

[0210] The flow rates of the first suction flow and the second suction flow can be formed differently. Since the first suction flow and the second suction flow are flow-separated by the second partition wall (123), flow loss caused by the pressure difference between the mutual flows can be prevented.

[0211] The flow rate of the first suction flow may be formed to be greater than that of the second suction flow. For example, the flow rate of the second suction flow may be formed at about 60% of the flow rate of the first suction flow. For example, the first suction flow rate may be generated at about 170 CMH, and the second suction flow rate may be generated at about 100 CMH.

[0212] The above first suction flow is a flow of air to be dehumidified and requires a large amount, but the above second suction flow may require a relatively small amount to condense moisture in the heat exchanger (160).

[0213] The above fan (150) can be controlled so that the first suction side, where the first suction flow is sucked, has a greater suction flow rate than the second suction side, where the second suction flow is sucked.

[0214] The dehumidification module (300) may be placed in the space between the second partition wall (123) and the first suction unit (110a). The space between the second partition wall (123) and the first suction unit (110a) may be called a “dehumidification module space.”

[0215] The fan (150) and the heat exchanger (160) may be placed in the space between the second partition wall (123) and the second suction part (115a). The space between the second partition wall (123) and the second suction part (115a) may be called a “fan space” or a “heat exchanger space.”

[0216] The air sucked through the first suction portion (110a) can be separated from moisture after passing through the dehumidifying module (300). The air from which moisture has been separated can be sucked into the suction side of the fan (150) after passing through the second partition wall (123).

[0217] The fan (150) may include a bidirectional suction fan that sucks in air from both directions and discharges it. For example, the fan (150) may include a bidirectional centrifugal fan that sucks in air in the axial direction on both sides and discharges it in the radial direction.

[0218] The suction side of the fan (150) through which air passing through the dehumidifying module (300) is sucked in can be referred to as the “first suction side.” That is, the first suction flow can be understood as air flow flowing from the first suction portion (110a) to the first suction side of the fan (150).

[0219] The fan (150) may include a main plate (151), a first blade (151a) arranged on one side of the main plate (151) and positioned on a first suction side, and a second blade (151b) arranged on the other side of the main plate (151) and positioned on a second suction side. The first and second blades (151a, 151b) may be arranged opposite each other with respect to the main plate (151).

[0220] The above dehumidification module (300) can be detachably mounted inside the main body (100).

[0221] The above dehumidifier (10) may further include a module mounting guide (125) that guides mounting of the dehumidifying module (300). The module mounting guide (125) may constitute a part of the first part (A).

[0222] The above module mounting guide (125) is provided on the inside of the main body (100) and can be connected to the second partition wall (123). The module mounting guide (125) can extend from the second partition wall (123) in a direction toward the first suction portion (110a).

[0223] The above module mounting guides (125) are provided in multiple numbers, and the multiple module mounting guides (125) can be spaced apart from each other. The dehumidifying module (300) can be mounted in the space between the multiple module mounting guides (125).

[0224] The above plurality of module mounting guides (125) can be arranged adjacent to or in contact with both sides of the dehumidifying module (300).

[0225] The heat exchanger (160) may be placed inside the second suction portion (115a). Accordingly, the heat exchanger (160) may be placed so that air introduced into the first part (A) through the second suction portion (115a) passes therethrough.

[0226] The heat exchanger (160) may be placed between the second suction part (115a) and the fan (150). Accordingly, the air sucked through the second suction part (115a) may pass through the heat exchanger (160) and then be sucked into the suction side of the fan (150). At this time, the air may condense the water vapor separated from the dehumidification module (300) while exchanging heat with the water vapor.

[0227] The suction side of the fan (150) into which air passing through the heat exchanger (160) is sucked can be called the “second suction side.” That is, the second suction flow can be understood as air flow flowing from the second suction part (115a) to the second suction side of the fan (150).

[0228] The above first suction flow and the above second suction flow can be sucked in the axial direction of the fan (150) and discharged in the radial direction, and then discharged through the discharge portion (106) provided on the upper surface (105) of the dehumidifier (10).

[0229] The above second part (B) may be provided on the lower side of the first bulkhead (121).

[0230] The second part (B) may further include a third partition wall (126) that divides the installation space of the vacuum pump (230) and the installation space of the tank (250, 260). The third partition wall (126) may divide the installation space of the vacuum pump (230) and the installation space of the tank (250, 260) in the front-rear direction.

[0231] By the third partition wall (126), the noise generated from the vacuum pump (230) can be prevented from being transmitted to the front side of the dehumidifier (10), i.e., the installation space of the tank (250, 260) that users frequently access.

[0232] The above third bulkhead (126) can easily provide an installation area for a sensor (256) for detecting the water level of the tank (250, 260) and a delivery path for condensate delivered to the drain tank (250).

[0233] The third bulkhead (126) is connected to the base (210) forming the lower surface of the dehumidifier (10) and may be configured to protrude upward from the base (210).

[0234] The above second part (B) may further include a fourth partition wall (127, see FIG. 16) that divides the installation space of the tank (250, 260) into an installation space of the drain tank (250) and an installation space of the water supply tank (260). The fourth partition wall (127) may divide the installation space of the drain tank (250) and the installation space of the water supply tank (260) in the left and right directions.

[0235] The above tank (250, 260) can be detachably mounted on the dehumidifier (10).

[0236] The second part (B) may include a tank mounting guide (128) provided on both left and right sides of the base (210) to guide mounting of the tank (250, 260).

[0237] The above tank mounting guide (128) may include a first mounting guide (128a) that guides the mounting of the drain tank (250). The first mounting guide (128a) may be connected to the base (210) and configured to protrude upward from the base (210).

[0238] The above drain tank (250) can be detachably mounted in the space between the fourth bulkhead (127) and the first mounting guide (128a). The first mounting guide (128a) can be positioned adjacent to or in contact with one side of the drain tank (250).

[0239] The above tank mounting guide (128) may include a second mounting guide (128b) that guides the mounting of the water supply tank (260). The second mounting guide (128b) may be connected to the base (210) and configured to protrude upward from the base (210).

[0240] The above water supply tank (260) can be detachably mounted in the space between the fourth bulkhead (127) and the second mounting guide (128b). The second mounting guide (128b) can be positioned adjacent to or in contact with one side of the water supply tank (260).

[0241] The above base (210) may include a rail (215) that guides the mounting of the tank (250, 260). The rail (215) may be configured to protrude from the base (210) and extend in the direction in which the tank (250, 260) is mounted, i.e., in the front-back direction. The rail (215) may be provided on the lower side of the drain tank (250) and the lower side of the water supply tank (260), respectively.

[0242] The above plurality of rails (215) can be inserted into a rail groove formed on the bottom surface of the drain tank (250) and a rail groove formed on the bottom surface of the water supply tank (260).

[0243] The above dehumidifier (10) may include an air supply device (170, 172) that supplies air to the dehumidification module (300) in order to improve the dehumidification performance in the dehumidification module (300). The air supply device (170, 172) may be configured to supply at least a portion of the air discharged from the fan (150) to the dehumidification module (300).

[0244] The above air supply device (170, 172) may include a valve device (170) arranged on the discharge side of the fan (150). For example, the valve device (170) may be arranged on the second partition wall (123). In particular, the second valve device (170) may be arranged at a position adjacent to the upper end of the second partition wall (123) adjacent to the discharge side of the fan (150).

[0245] At least a portion of the air discharged from the fan (150) may be introduced into the second valve device (170) through the guide hole (123b, see FIG. 16). The guide hole (123b) may be formed in the second partition wall (123).

[0246] The above second valve device (170) can be installed in the guide hole (123b).

[0247] The above air supply device (170, 172) is connected to the valve device (170) and may further include a supply pipe (172) that supplies air passing through the valve device (170) to the dehumidification module (300). The supply pipe (172) may be connected to a connection port (354) of the dehumidification module (300).

[0248] The above dehumidifier (10) may include a connection pipe (235) through which water vapor separated from the dehumidifying module (300) flows and a vacuum pump (230) connected to the connection pipe (235). The connection pipe (235) may be referred to as a “water vapor connection pipe.”

[0249] The above connecting pipe (235) is connected to the dehumidifying module (300) and includes a first connecting pipe (235a, see FIG. 20) connected to the suction side of the vacuum pump (230), and water vapor separated from the dehumidifying module (300) can be sucked into the vacuum pump (230) through the first connecting pipe (235a).

[0250] The first connecting pipe (235a) extends from the bottom surface of the first partition wall (121), and a port communication hole (121c, see FIG. 16) connected to the dehumidifying module (300) may be formed in the first partition wall (121).

[0251] The above connecting pipe (235) is connected to the discharge side of the vacuum pump (230) and includes a second connecting pipe (235b, see FIG. 21) connected to the heat exchanger (160), and high-temperature steam discharged from the vacuum pump (230) can be introduced into the heat exchanger (160) through the second connecting pipe (235b).

[0252] The water vapor passing through the vacuum pump (230) may be compressed by the vacuum pump (230) and may have a high temperature, for example, a temperature of about 45 to 50°C. The vacuum pump (230) may also be called a “vacuum compression pump.”

[0253] The water vapor passing through the vacuum pump (230) can form a flow rate less than about 5% of the total suction flow rate of the system, i.e., the flow rate sucked through the first suction unit (110a). Therefore, the water vapor can be sufficiently converted into condensate through heat exchange with the air sucked through the second suction unit (115a).

[0254] The second connecting pipe (235b) may be connected to the inlet port (121a, see FIG. 16) of the first bulkhead (121). The inlet hole (121a) may be coupled to the inlet of the heat exchanger (160).

[0255] The above heat exchanger (160) may be configured to exchange heat between the air sucked in from the second suction portion (115a) and the steam introduced through the second connecting pipe (235b). Since the temperature of the sucked air is lower than the temperature of the separated steam, condensation of the steam may occur during the heat exchange process.

[0256] For example, the second connecting pipe (235b) may be connected to the lower part of the heat exchanger (160).

[0257] The above dehumidifier (10) further includes a condensate pipe (236) through which condensed water from the heat exchanger (160) flows, and the condensate pipe (236) can be connected to the discharge side of the heat exchanger (160). For example, the condensate pipe (236) can be connected to the lower end of the heat exchanger (160).

[0258] The above condensate pipe (236) is connected to the discharge port (121b, see FIG. 16) of the first bulkhead (121) and can extend from the bottom surface of the first bulkhead (121).

[0259] The above condensate pipe (236) is provided in the second part (B) and can be arranged to communicate with the space where the drain tank (260) is installed.

[0260] The above dehumidifier (10) may further include a water pump (180) that is fluidly connected to the water supply tank (260) and provides driving force to supply water from the water supply tank (260) to the dehumidification module (300).

[0261] For example, the water pump (180) may be placed in the first part (A) and mounted on the upper side of the first bulkhead (121). However, this is not limited to the first part (A), and the water pump (180) may also be placed in the second part (B).

[0262] The above dehumidifier (10) is connected to the water pump (180) and may further include a water supply connection pipe (185) that transfers water from the water supply tank (260) to the dehumidification module (300).

[0263] The above water supply connection pipe (185) is connected to the duct (263) of the water supply tank (260) and may include a first connection pipe (185a) that transfers water from the water supply tank (260) to the water pump (180). The first connection pipe (185a) may pass through the first bulkhead (121) and be connected to the water pump (180).

[0264] The above first bulkhead (121) may include a water supply penetration hole (121d, see FIG. 16) through which the first connecting pipe (185a) passes.

[0265] The above water supply connection pipe (185) is connected to the water pump (180) and may include a second connection pipe (185b) extending to the dehumidification module (300). The second connection pipe (185b) may be connected to the water supply port (317) of the dehumidification module (300).

[0266] Fig. 16 is an exploded perspective view of a dehumidifier according to an embodiment of the present invention, and Fig. 17 is a cross-sectional view taken along line 17-17 of Fig. 11.

[0267] Referring to FIG. 16, a dehumidifier (10) according to an embodiment of the present invention may include a main body (100) that accommodates a plurality of components for dehumidifying air.

[0270] The upper surface (105) may include a discharge portion (106) for discharging air, a discharge vane (107) for opening and closing the discharge portion (106), and a display portion (108).

[0271] A sealing member (105a) may be provided between the open upper portion of the main body (100) and the upper surface (105) to prevent air leakage.

[0272] The above body (100) may include a first suction portion (110a) through which a first suction flow is suctioned. The first suction portion (110a) is formed by penetrating at least a portion of the front portion (101), and a first suction grill (110) may be mounted on the first suction portion (110a).

[0273] The above body (100) may include a second suction portion (115a) through which a second suction flow is suctioned. The second suction portion (115a) is formed by penetrating at least a portion of the rear portion (102), and a second suction grill (115) may be mounted on the second suction portion (115a).

[0274] Between the first suction part (110a) and the second suction part (115a), a dehumidification module (300), a fan (150), and a heat exchanger (160) can be sequentially arranged in a direction from the first suction part (110a) toward the second suction part (115a).

[0275] A communication portion (121a, 121b, 121c) through which steam or condensate passes may be formed in the first partition wall (121) that divides the dehumidifier (10) into a first part (A) and a second part (B). The communication portion (121a, 121b, 121c) may include a port communication hole (121c) that guides steam separated from the dehumidifying module (300) to flow to the vacuum pump (230).

[0278] The above dehumidifier (10) may include a second partition wall (123) extending upward from the first partition wall (121) and dividing the internal space of the first part (A) into a space where the dehumidification module (300) is located and a space where the fan (150) and the heat exchanger (160) are located.

[0279] The second partition wall (123) is formed on the outlet side of the dehumidifying module (300) based on the first suction flow, and can form a fan suction part (123a) that guides air passing through the dehumidifying module (300) to the suction side of the fan (150).

[0280] The above fan suction part (123a) may include a suction guide (bell mouth) formed in a round shape so that air can be smoothly sucked in the axial direction of the fan (150).

[0281] The above dehumidifier (10) may include two module mounting guides (125) that protrude from the second partition wall (123) and guide the mounting of the dehumidifying module (300). The module mounting guides (125) may protrude from the second partition wall (124) in a direction toward the first suction portion (110a).

[0282] The two module mounting guides (125) above can be arranged on both sides of the fan suction portion (123a). The front-rear width of the dehumidifying module (300) supported by the two module mounting guides (125) can be formed to be larger than the diameter of the fan suction portion (123a). Accordingly, the dehumidifying module (300) can cover the fan suction portion (123a).

[0283] The above first suction flow passes through the second partition wall (123) via the fan suction portion (123a) and can be sucked into the first suction side of the fan (150).

[0284] The second suction flow sucked through the second suction portion (115a) can be sucked into the second suction side of the fan (150) after passing through the heat exchanger (160).

[0285] The dehumidifier (10) may further include a plate (124) coupled to the second partition wall (123). For example, the plate (124) may be coupled to the upper portion of the second partition wall (123) and may protrude in a direction toward the front portion (101).

[0286] The above plate (124) may be arranged to divide the space between the upper surface (105) and the upper end of the dehumidifying module (300). By driving the vacuum pump (230), vacuum pressure is applied to the dehumidifying module (300), and the plate (124) can block the vacuum pressure from applying to the upper surface (105).

[0287] The above body (100) may include an opening (103a) for forming an inlet space in which a tank (250, 260) is mounted. The opening (103a) is formed from the front portion (101) to both side portions (103, 104), and may be configured to open in the direction in which the tank (250, 260) is withdrawn or introduced.

[0288] Referring to Fig. 17, the first part (A) may include a fan motor (155) for driving the fan (150). The fan motor (155) may be coupled to a central hub (151) of the fan (150). The shaft of the fan motor (155) may be coupled to the hub (151) in an axial direction (front-backward direction).

[0289] The center line (ℓ) passing through the center of the fan motor (155) in the front-back direction may pass through the dehumidifying module (300), the fan suction part (123a), and the heat exchanger (160). For example, the center line (ℓ) may pass through the center of the dehumidifying module (300), the center of the fan suction part (123a), and the center of the heat exchanger (160).

[0290] The dehumidification module (300) can be installed on the first bulkhead (121).

[0291] The above dehumidification module (300) may include a dehumidification member (320) that performs selective separation of moisture.

[0292] The above dehumidifying module (300) may further include a fixing member (330) that supports an end of the dehumidifying member (320) and a first cap (340) that fills the fixing member (330).

[0294] The above-mentioned fixing member (330), the first cap (340), and the second cap (350) may be provided on each side of the dehumidifying member (320). That is, the above-mentioned fixing member (330), the first cap (340), and the second cap (350) may be provided on the upper and lower sides of the dehumidifying member (320), respectively.

[0295] The bottom surface of the above dehumidification module (300) can be coupled to the first bulkhead (121).

[0296] The dehumidifying module (300) may include a connection port (360) that protrudes from the second cap (350) in a direction toward the first partition wall (121). The connection port (360) may be coupled to a protrusion (122) of the first partition wall (121). The protrusion (122) may protrude downward from the bottom surface of the first partition wall (121).

[0297] For example, the connection port (360) can be inserted into the inside of the protrusion (122).

[0298] A sealing member (365) may be provided on the outer surface of the connection port (360) to seal the space between the protrusion (122) and the connection port (360). By the sealing member (365), the connection port (360) and the protrusion (122) can be firmly connected.

[0299] The above sealing member (365) may be provided in multiple pieces.

[0300] A cap hole (355) is formed in the second cap (350), and the cap hole (355) can be extended to the connection port (360). Moisture (water vapor) separated from the dehumidifying module (300) can be discharged to the outside of the dehumidifying module (300) through the cap hole (355).

[0303] FIG. 18 is a drawing showing a state in which a first suction flow and a discharge flow are generated in a dehumidifier according to a first embodiment of the present invention, FIG. 19 is an upper perspective view showing the configuration of a first part and a second part in a dehumidifier according to a first embodiment of the present invention, FIG. 20 is a lower perspective view showing the configuration of a first part and a second part in a dehumidifier according to a first embodiment of the present invention, and FIG. 21 is a drawing showing a part of a configuration of a dehumidifier according to a first embodiment of the present invention.

[0304] Referring to FIGS. 18 to 21, the dehumidifier (10) according to the first embodiment of the present invention can generate a first suction flow as the main flow of air to be dehumidified by driving the fan (150).

[0305] When the fan (150) above is driven, air can be sucked in through the first suction portion (110a) in a direction intersecting the front portion (101). The air sucked in through the first suction portion (110a) can pass in a direction in which the plurality of dehumidifying members (320) extend, i.e., in a direction intersecting the vertical direction (front-back direction).

[0306] By driving the vacuum pump (230), a negative pressure lower than the external pressure can be formed inside the dehumidifying member (320). As air passes through the dehumidifying member (320), moisture contained in the air can come into contact with the surface of the dehumidifying member (320) and be adsorbed. Then, the adsorbed moisture can be selectively separated from the humid air by diffusing and then being desorbed from the surface.

[0307] The separated moisture flows downward inside the dehumidifying member (320) and can flow into the cap hole (355) of the second end cap (350b). That is, the flow direction (downward) of the separated moisture (dotted arrow in FIG. 18) can form a direction perpendicular to the flow direction (front-back direction) of the air (solid arrow in FIG. 18).

[0308] The air from which the moisture has been separated can be sucked in the axial direction of the fan (150). At this time, the air that has passed through the dehumidifying module (300) can be sucked into the hub (151) of the fan (150) through the fan suction portion (123a) of the second partition wall (123). A fan motor (155) can be coupled to the hub (151).

[0309] The fan (150) may include a plurality of blades (152) arranged in the circumferential direction of the hub (151). By the rotation of the plurality of blades (152), air sucked in the axial direction (front-back direction) of the fan (150) may be discharged in the radial direction of the fan (150).

[0310] The refrigerant discharged from the above fan (150) flows upward toward the upper surface (105) and can be discharged from the discharge portion (106).

[0311] Referring to FIGS. 20 and 21, the dehumidification module (300) and the heat exchanger (160) may be spaced apart from each other with a fan (150) therebetween. When the fan (150) is driven, a first suction flow flowing from the dehumidification module (300) to the first suction side of the fan (150) and a second suction flow flowing from the heat exchanger (160) to the second suction side of the fan (150) may be generated.

[0312] The above fan (150) may be configured as a two-way suction fan so that the first suction flow and the second suction flow can be generated.

[0313] Based on the first partition wall (121), a first connecting pipe (235a) that forms a path for water vapor separated from the dehumidifying module (300) may be provided on the lower side of the first partition wall (121).

[0314] The first connecting pipe (235a) may extend from the bottom surface of the dehumidifying module (300) to the suction side of the vacuum pump (230). At this time, the first connecting pipe (235a) may extend to the vacuum pump (230) by penetrating the third partition wall (126).

[0315] A second connecting pipe (235b) may be provided on the lower side of the first bulkhead (121) to form a path for steam flowing into the heat exchanger (160) through the vacuum pump (230). The second connecting pipe (235b) may extend from the discharge side of the vacuum pump (230) to the bottom surface of the heat exchanger (160).

[0316] A condensate pipe (236) for discharging condensate generated in the heat exchanger (160) may be provided on the lower side of the first bulkhead (121). The condensate pipe (236) extends from the bottom surface of the heat exchanger (160) and may be coupled to a second through-hole (126b, see FIG. 25) of the second bulkhead (126). The condensate flowing through the condensate pipe (236) may flow into the drain tank (250) through the second bulkhead (126).

[0317] The second suction flow of air sucked in from the second suction portion (115a) can pass through the heat exchanger (160) and then be sucked into the second suction side of the fan (150). Then, the air is discharged in the radial direction of the fan (150) and can flow upwards by hitting the fan discharge portion (157) provided at the top of the fan (150).

[0318] At least a portion of the air passing through the fan (150) may be introduced into the guide hole (123b) adjacent to the upper end of the fan (150). The guide hole (123b) may be formed by penetrating the second partition wall (123).

[0319] Air can be introduced into the valve device (170) provided in the partition wall (123) through the guide hole (123b). The valve device (170) can be placed in the space where the dehumidification module (300) is installed in the guide hole (123b).

[0320] A supply pipe (172) is connected to the above valve device (170), and the supply pipe (174) can be connected to the connection port (354) of the dehumidification module (300).

[0321] The above valve device (170) is provided so as to be openable or closed, and when the valve device (170) is opened, air can be supplied to the distribution plate (356) side of the dehumidifying module (300) through the valve device (170) and the supply pipe (172).

[0322] FIG. 22 is a drawing showing a state in which a first suction flow and a second suction flow are sucked and a discharge flow is generated in a dehumidifier according to a first embodiment of the present invention, and FIG. 23 is a drawing showing a state in which a fluid is supplied from a water supply tank to a dehumidification module in a dehumidifier according to a first embodiment of the present invention.

[0323] First, referring to FIG. 22, when the two-way suction fan (150) according to the first embodiment of the present invention is driven, a first suction flow flowing into the interior of the dehumidifier (10) through the first suction part (110a) and a second suction flow flowing into the interior of the dehumidifier (10) through the second suction part (115a) can be generated.

[0324] The above first suction flow can separate moisture (water vapor) from the air while passing through the dehumidification module (300). The air from which moisture has been separated can be sucked in in the axial direction through the first suction side of the fan (150) and flow in the radial direction to be discharged through the top of the fan (150).

[0325] The separated moisture can be discharged downward from the dehumidifying module (300) and introduced into the heat exchanger (160) through the connecting pipe (235) and the vacuum pump (230).

[0326] The above second suction flow passes through the heat exchanger (160), and in this process, moisture introduced into the heat exchanger (160) can be condensed. The air with the moisture condensed can be discharged from the heat exchanger (160) and axially sucked in through the second suction side of the fan (150).

[0327] The second suction flow passing through the fan (150) may flow in the radial direction and be discharged through the upper end of the fan (150). The second suction flow may be combined with the first suction flow and flow upward and be discharged through the discharge portion (106) of the dehumidifier (10). The discharge vane (107) may control the amount of air discharged from the discharge portion (106).

[0328] At least a portion of the air discharged from the top of the fan (150) may be introduced into the valve device (170) through the guide hole (123b) formed in the second partition wall (123). At this time, the valve device (170) may be opened, and the air may be supplied to the dehumidifying module (300) through the valve device (170) and the supply pipe (172).

[0329] The air supplied to the above dehumidifying module (300) can remove water vapor accumulated inside the dehumidifying member (320).

[0330] Next, referring to FIG. 23, when the water pump (180) is driven, the water stored in the water tank (260) can be supplied to the dehumidification module (300) through the water supply connection pipe (185) and the water pump (180).

[0331] The water supplied to the dehumidifying module (300) flows into the water supply duct (315a) of the dehumidifying module (300) and can be supplied to the periphery of the dehumidifying member (320) through the water supply hole (316). Since the water can contact the surface of the dehumidifying member (320) due to the suction force of the fan (150), the dehumidifying member (320) can become wet, and thus the moisture separation performance of the dehumidifying member (320) can be improved.

[0332] Figure 24 is a perspective view of a dehumidifying module according to a second embodiment of the present invention.

[0333] Referring to Fig. 24, a dehumidifying module (300a) according to a second embodiment of the present invention may include a plurality of supports (314a1, 314a2, 314b1, 314b2) provided on both sides of a dehumidifying member (320). The configuration of the dehumidifying module (300a) according to this embodiment is identical to the configuration of the dehumidifying module of the first embodiment except for the configuration of the supports, and thus the description of the first embodiment may be used.

[0334] The above-described plurality of supports may include two first supports (314a1, 314a2) provided on one side, for example, the left side, of the dehumidifying module (300a). The two first supports (314a1, 314a2) are arranged spaced apart from each other in the direction of flow of humid air, and can secure longitudinal support force of the dehumidifying module (300a).

[0335] The above-described plurality of supports may include two second supports (314b1, 314b2) provided on the other side, for example, the right side, of the dehumidifying module (300a). The two second supports (314b1, 314b2) are arranged spaced apart from each other in the direction of flow of humid air, and can secure longitudinal support force of the dehumidifying module (300a).

[0336] The above two first supports (314a1, 314a2) and the above two second supports (314b1, 314b2) can be placed in the first hole (311a) and the second hole (311b) of the housing (310), respectively.

[0337] In this embodiment, it is described that two supports are provided on each side of the dehumidification module, but alternatively, three or more supports may be provided on each side of the dehumidification module.

[0338] A dehumidifying module according to an embodiment of the present invention comprises a dehumidifying member including a membrane with which moist air comes into contact, and a cap having a potting portion for securing at least one side of the dehumidifying member, thereby increasing the contact surface area between the moist air and the dehumidifying member and improving moisture separation performance. Therefore, the dehumidifying module has remarkable industrial applicability.
