Description

Dehumidifying module, method for manufacturing the dehumidifying module, and dehumidifier including the dehumidifying module

[0001] The present invention relates to a dehumidifying module, a method for manufacturing the dehumidifying module, and a dehumidifier including the dehumidifying module.

[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 dehumidifier capable of implementing constant temperature dehumidification without increasing the temperature of an indoor space by selectively separating moisture in the air through a dehumidification module including a membrane without operating a refrigeration cycle.

[0008] The present invention aims to provide a dehumidifier in which dehumidification can be performed by passing through a dehumidification module without requiring time for stabilization of a refrigeration cycle, thereby shortening the dehumidification time.

[0009] The purpose of the present invention is to provide a dehumidifier capable of increasing the amount of air sucked into the dehumidifier by forming a cylindrical suction portion.

[0010] The purpose of the present invention is to provide a dehumidifier having a dehumidifying module having a cylindrical structure, thereby increasing the contact area of ​​air flow to the dehumidifying module and reducing the size of the dehumidifying module compared to dehumidifying modules of other shapes having the same contact area.

[0011] The purpose of the present invention is to provide a dehumidifier having a dehumidifying module having a contact area in the circumferential direction, thereby reducing the thickness of the dehumidifying module, thereby reducing pressure loss, and improving dehumidifying performance by maximizing the membrane area of ​​the dehumidifying member.

[0012] The purpose of the present invention is to provide a dehumidifier that forms a through hole penetrating in the axial direction of a dehumidifying module so that dehumidified air can easily be discharged through the through hole while passing from the outer surface to the inner surface of the dehumidifying module.

[0013] The present invention aims to provide a dehumidifier that is arranged to increase the amount or density of a dehumidifying member in an area that comes into contact with humid air having a relatively large amount of moisture.

[0143] The above port communication holes (216) may be formed in multiple numbers corresponding to the number of connection ports (131 to 134). For example, the multiple port communication holes (216) may be spaced apart from each other and arranged to form a central angle of 90 degrees. However, although the drawing shows four port communication holes being formed, three or fewer or five or more port communication holes may be formed.

[0144] The second part (200) is connected to the port communication hole (216) and may further include a first connecting pipe (235) that guides the water vapor separated from the dehumidifying module (120) to the vacuum pump (230). The water vapor may be understood as air containing moisture.

[0145] The above vacuum pump (230) can be installed inside the second housing (210). The vacuum pump (230) is placed on the base panel (216), and the base panel (216) can be placed on the bottom surface (211) of the second housing (210).

[0146] The above vacuum pump (230) can be understood as a component that sucks in moisture (water vapor) separated from the dehumidifying module (120), compresses it at high pressure, discharges the compressed air, and sends it to the moisture separator (260). The above vacuum pump (230) may also be called a “vacuum compression pump.”

[0147] The vacuum pump (230) may include a pump inlet (232) connected to the first connecting pipe (235). For example, the pump inlet (232) may be formed at one end of the vacuum pump (230).

[0148] The vacuum pump (230) may further include a pump discharge portion (234) for discharging compressed air. For example, the pump discharge portion (234) may be formed at the other end of the vacuum pump (230).

[0149] A second connecting pipe (236) may be connected to the pump discharge portion (234). The second connecting pipe (236) may extend from the pump discharge portion (234) to a pressure relief valve (240).

[0150] A moisture separator (260) may be installed in the second connecting pipe (236). High-pressure air discharged from the vacuum pump (230) may be introduced into the moisture separator (260) through the second connecting pipe (236). In addition, moisture (water) in the air may be separated in the moisture separator (260), and the separated water may be introduced into a water tank (250).

[0151] The second connecting pipe (236) may include a first pipe (236a, see FIG. 7) extending from the vacuum pump (230) to the moisture separator (260) and a second pipe (236b, see FIG. 7) extending from the moisture separator (260) to the pressure relief valve (240).

[0152] The second housing (210) may further include a discharge port (217) through which air, after water has been separated from the high-pressure wet air discharged from the vacuum pump (230) in the moisture separator (260), is discharged from the second part (200).

[0153] The above discharge port (217) protrudes upward from the upper surface (212) and can be located inside the through hole (125) of the dehumidifying module (120).

[0154] The above discharge port (217) may constitute at least a portion of the pressure relief valve (240). That is, the discharge port (217) may be formed by a housing that constitutes the exterior of the pressure relief valve (240). The discharge port (217) may also be referred to as a “valve housing.”

[0155] The above pressure relief valve (240) may be configured to have a preset reference pressure and to be closed when the reference pressure is lower than the reference pressure and open when a pressure higher than the reference pressure is applied.

[0156] When the vacuum pump (230) is driven and a pressure higher than the reference pressure is applied, the pressure relief valve (240) opens and high-pressure air can be discharged from the vacuum pump (230). The pressure relief valve (240) can be connected to the outlet side of the vacuum pump (230).

[0157] Considering the phase change property of water, the compressed air discharged from the vacuum pump (230) can contain a large amount of moisture by utilizing the fact that gas changes into liquid when pressure increases.

[0158] The second part (200) may further include a moisture separator (260) connected to the outlet side of the vacuum pump (230). The compressed air containing a large amount of moisture is introduced into the moisture separator (260), and water in the air can be separated. The separated water can be collected in a water tank (250).

[0159] For example, the moisture separator (260) may include a cyclone-type moisture separator that separates water from the air by generating a cyclone-shaped air flow.

[0160] The above moisture separator (260) may be placed between the vacuum pump (230) and the pressure relief valve (240) based on the air flow.

[0161] The reference pressure set in the above pressure relief valve (240) may be formed in the range of 2 to 3 (bar). The higher the reference pressure, the higher the possibility that gas in the air will change into liquid. However, if the reference pressure is set too high, the pump performance may be limited, so setting the reference pressure to an appropriate level may be required.

[0162] The above pressure relief valve (240) may include a pipe connection portion (241) forming a first opening portion (241a) to which a second pipe (236a) of a second connection pipe (236) is connected. A portion of the pipe connection portion (241) may be disposed on the lower side of the upper surface portion (212), and another portion may be disposed on the upper side of the upper surface portion (212).

[0163] The above pressure relief valve (240) may further include a plunger (242) that is movably provided inside the valve housing forming the discharge port (217). When the pressure acting on the pressure relief valve (240) becomes higher than the reference pressure, the plunger (242) can move.

[0164] The above pipe connection part (241) may include a second opening part (241b) that is selectively opened and closed by the plunger (242). The first opening part (241a) may be formed at one end of the pipe connection part (241), and the second opening part (241b) may be formed at the other end of the pipe connection part (241).

[0165] When a pressure lower than the reference pressure is applied to the pressure relief valve (240), the plunger (242) may be in a position to close the second opening (241b) by the restoring force of the spring (245). For example, the reference pressure may be set by adjusting the elastic coefficient of the spring (245).

[0166] The spring (245) is provided inside the valve housing (217) and one end thereof may be supported by a spring support member (246). The other end of the spring (245) may be supported by the plunger (242).

[0167] The spring support (246) may be provided on the upper inner side of the valve housing (217). A spring (245) may be supported at the center of the spring support (246), and exhaust holes (246a) through which air is discharged may be formed at both sides.

[0168] When a pressure higher than the reference pressure is applied to the pressure relief valve (240), the plunger (242) moves upward while compressing the spring (245), and the second opening (241b) can be opened.

[0169] Air is discharged through the above-mentioned open second opening (241b), and the discharged air can be discharged from the pressure relief valve (240) through the discharge hole (246a).

[0170] The second housing (210) may include a side surface (213) connecting the bottom surface (211) and the top surface (212). The side surface (213) may form a side appearance of the second housing (210).

[0171] In the above side portion (213), a slit (213a) may be formed as a communication portion communicating with the outside of the second part (200).

[0172] The second part (200) may further include a front portion (214) forming an opening (214a). A water tank (250) may be detachably mounted in the opening (214a). The water tank (250) may be inserted into the opening (214a) and may be pulled backward. A user may pull the water tank (250) forward to detach it.

[0173] The water tank (250) is connected to a water separator (260), and the outlet of the water separator (260) can be fluidly connected to the inlet of the water tank (250). Accordingly, water discharged from the water separator (260) can flow into the water tank (250).

[0174] FIG. 4 is a perspective view showing a first housing according to an embodiment of the present invention, FIG. 5 is a drawing showing a lower configuration of a dehumidifier according to an embodiment of the present invention, and FIG. 6 is a drawing showing a connection configuration of a connection port of a dehumidification module and a vacuum pump according to an embodiment of the present invention.

[0175] First, referring to FIG. 4, the first housing (110) according to the embodiment of the present invention may have a cylindrical shape with an empty interior.

[0176] The first housing (110) may include a first housing part (110a) in which the dehumidifying unit is accommodated. The first housing part (110a) may extend upward to have a first height set from the lower end of the first housing (110).

[0177] The first housing (110) may include a second housing part (110b) that accommodates the blower (110b). The second housing part (110b) may extend downward from the upper end of the first housing (110) to have a second height set.

[0178] The above second housing part (110b) can be formed on the upper side of the above first housing part (110a).

[0179] The first housing (110) may include a suction unit (112) for sucking air. The suction unit (112) includes a plurality of suction holes, and the plurality of suction holes may be formed to form a plurality of rows in a circumferential direction and a plurality of columns in a vertical direction.

[0180] The above suction part (112) may include a first suction part (112a) formed at the lower portion of the first housing part (110a) and a second suction part (112b) formed at the upper portion of the second housing part (110a). The second suction part (112b) may be arranged above the first suction part (112a).

[0181] The first suction part (112a) and the second suction part (112b) may each include a plurality of suction holes.

[0182] The suction area of ​​the first suction unit (112a) may be larger than the suction area of ​​the second suction unit (112b). Since the blower is positioned above the dehumidifying unit, the distance from the fan (160) to the first suction unit (112a) may be larger than the distance from the fan (160) to the second suction unit (112b).

[0183] Accordingly, a condition may be created in which the suction amount through the first suction part (112a) becomes smaller than the suction amount through the second suction part (112b). To compensate for this, the suction area of ​​the first suction part (112a) may be created to be larger than the suction area of ​​the second suction part (112b).

[0184] For example, in order to form the suction area in the first suction part (112a) larger than the suction area in the second suction part (112b), the number of suction holes provided in the first suction part (112a) may be formed to be greater than the number of suction holes provided in the second suction part (112b).

[0185] As another example, in order to form the suction area in the first suction part (112a) larger than the suction area in the second suction part (112b), the area of ​​the suction hole provided in the first suction part (112a) can be formed larger than the area of ​​the suction hole provided in the second suction part (112b).

[0186] Of course, the number and area of ​​suction holes provided in the first suction part (112a) may be formed to be larger than the number and area of ​​suction holes provided in the second suction part (112b).

[0187] In a state where the first housing (110) accommodates the dehumidifying module (120), the lower portion of the dehumidifying module (120) may be positioned lower than the lower portion of the first housing (110). The lower portion of the dehumidifying module (120) may be supported or mounted on the upper surface (212) of the second housing (210).

[0188] The lower part of the above dehumidification module (120) may include a cap (130). The cap (130) may be provided with connection ports (131 to 134) for discharging moisture (water vapor) separated from the dehumidification module (120). A plurality of connection ports (131 to 134) may be provided.

[0189] The above-mentioned plurality of connection ports (131 to 134) may include a first connection port (131), a second connection port (132), a third connection port (133), and a fourth connection port (134). The number of the connection ports (131 to 134) may correspond to the number of modules constituting the dehumidification module (120).

[0190] For example, the above-described multiple connection ports can be understood to be located in the first quadrant, the second quadrant, the third quadrant, and the fourth quadrant, respectively, when looking at the bottom surface (130a) of the cap (130).

[0191] In this embodiment, as an example, it is described that a dehumidifying module (120) is configured by assembling four modules, and four connection ports (131 to 134) are provided as described above. However, the number of modules and the number of connection ports (131 to 134) may not be limited to four.

[0192] The above-mentioned plurality of connection ports (131 to 134) may be configured to protrude downward from the bottom surface (130a) of the cap (130).

[0193] The bottom surface (130a) of the cap (130) may have a ring shape with a central portion penetrating upward and downward. The cap (130) may further include a penetrating opening (130b) penetrating the central portion of the bottom surface (130a).

[0205] The third coupler (237c) may include a third port. A seventh pipe (235g) may be connected to the third port of the third coupler (237c). Steam flowing through the fifth pipe (235e) and the sixth pipe (235f) may flow to the seventh pipe (235g) through the third port of the third coupler (237c).

[0206] The seventh pipe (235g) can extend from the third coupler (237c) to the vacuum pump (230). The seventh pipe (235g) can be connected to the pump inlet (232) of the vacuum pump (230).

[0207] The above vacuum pump (230) includes a pump discharge portion (234), and air compressed at high pressure in the vacuum pump (230) can be discharged through the pump discharge portion (234).

[0208] A second connecting pipe (236) is connected to the pump discharge portion (234), and the compressed air can be introduced into a moisture separator (260) through the second connecting pipe (236). The compressed air contains a high moisture content, and moisture (water) can be separated in the moisture separator (260).

[0209] The above moisture separator (260) may include a cyclone section (261) capable of centrifugally separating moisture by generating a cyclone flow of introduced air. The cyclone section (261) may include an inner peripheral surface having a cylindrical, cylindrical, or similar shape.

[0210] The separated water can be stored in a water tank (250) that is fluidly connected to the water separator (260).

[0211] The above water separator (260) can be coupled to the water tank (250). The water tank (250) can include a lower part (251) of the water tank forming a water storage space.

[0212] The water tank (250) may include a water tank upper portion (252) located above the water tank lower portion (251) and providing an area where the water separator (260) is coupled. The water tank upper portion (252) may form an inclined surface and may be configured to support the water separator (260) on the inclined surface.

[0213] FIG. 7 is a drawing showing a connection configuration of a vacuum pump and a water separator according to an embodiment of the present invention, FIG. 8 is a front view showing a connection configuration of a water separator and a water tank according to an embodiment of the present invention, FIG. 9 is a perspective view showing a connection configuration of a water separator and a water tank according to an embodiment of the present invention, and FIG. 10 is a side view showing a connection configuration of a water separator and a water tank according to an embodiment of the present invention.

[0214] Referring to FIGS. 7 to 10, a moisture separator (260) according to an embodiment of the present invention may be provided in a second part (200) of a dehumidifier.

[0215] The above moisture separator (260) can be connected to the second connecting pipe (236).

[0216] The second connecting pipe (236) may include a first pipe (236a) that is connected to the pump discharge portion (234) of the vacuum pump (230) and extends to the moisture separation inlet portion (260a) of the moisture separator (260). High-pressure air discharged from the vacuum pump (230) may flow through the first pipe (236a) and be introduced into the moisture separator (260) through the moisture separation inlet portion (260a).

[0217] The high pressure air above contains moisture (water) that has been transformed into a liquid by pressure, and the moisture can be separated while flowing inside the moisture separator (260).

[0218] The above moisture separator (260) may include a cyclone section (261) that separates moisture using a cyclone method (centrifugal separation method). The cyclone section (261) may include an inner surface or inner wall that guides moisture in the introduced air to fall upon collision. The fallen moisture may be introduced into a water tank (250).

[0219] The above moisture separator (260) may include a moisture separation discharge unit (260b) through which moisture-separated air is discharged. The second connecting pipe (236) may include a second pipe (236b) connected to the moisture separation discharge unit (260b).

[0220] The second pipe (236b) can extend from the moisture separation discharge unit (260b) to the pressure relief valve (240). Air flowing through the second pipe (236b) can pass through the open pressure relief valve (240) and flow toward the through hole (125) of the dehumidifying module (120) through the discharge port (217).

[0221] The above pressure relief valve (240) can be opened when a pressure higher than the reference pressure is applied. Specifically, when the vacuum pump (230) is operated and a set time has elapsed, if a pressure higher than the reference pressure is applied to the pressure relief valve (240), the plunger (242) can move to open the flow path within the valve.

[0222] When the flow path within the above valve is opened, high-pressure compressed air is discharged from the vacuum pump (230) and can flow through the moisture separator (260) to the pressure relief valve (240).

[0223] The water separator (260) may include a water discharge portion (265) through which separated water is discharged. The water discharge portion (265) may be provided at the lower end of the cyclone portion (261). For example, the water discharge portion (265) may protrude downward from the lower end of the cyclone portion (261), and at least a portion of the water discharge portion may be inserted into the inside of the water tank (250).

[0224] The water tank (250) may form a groove (253) in which at least a portion of the water separator (260) is positioned. The groove (253) may be formed in the upper portion (252) of the water tank. For example, the groove (253) may be formed to be sunken in the inclined surface (252a) of the upper portion (252) of the water tank.

[0225] A part of the moisture separator (260) can be inserted into the above home portion (253).

[0226] The inner surface of the above home portion (253) can form a guide surface (255) for guiding water discharged from the water discharge portion (265) to the water storage space (251) of the water tank (250).

[0227] In order for water discharged from the water discharge portion (265) to fall to the guide surface (255), the guide surface (255) may be formed on the lower side of the water discharge portion (265).

[0228] The above guide surface (255) can extend from the lower side of the water discharge portion (265) toward the inlet hole (254). The inlet hole (254) is formed by opening a portion of the groove portion (253) and can guide water to fall into the water storage space of the water tank (250).

[0229] The above guide surface (255) can extend downwardly from the lower portion of the water discharge portion (265) toward the inlet hole (254). Referring to Fig. 10, the above guide surface (255) can extend downwardly toward the inlet hole (254) at a set angle (θ) with respect to the horizontal line (ℓ).

[0230] Due to the downwardly inclined configuration of the above guide surface (255), water (fw) discharged from the water discharge portion (265) can easily flow toward the inlet hole (254).

[0232] First, referring to FIGS. 11 and 12, a dehumidification module (120) according to an embodiment of the present invention can be configured by assembling a plurality of modules.

[0233] The above multiple modules may include a first module (120a), a second module (120b), a third module (120c), and a fourth module (120d).

[0234] The first to fourth modules (120a, 120b, 120c, 120d) can be arranged in a circumferential direction and cooked. Any one of the first to fourth modules (120a, 120b, 120c, 120d) can be inserted between two other adjacent modules.

[0235] A boundary line (120e) may be formed between one of the above modules and the other two adjacent modules, which are arranged in contact with or adjacent to each other. Since four modules are provided, the dehumidifying module (120) may include four boundary lines (120e). However, the number of modules may not be limited thereto.

[0236] The above-described first to fourth modules (120a, 120b, 120c, 120d) may have substantially the same configuration. The following description will be based on one module, and it can be understood that the dehumidification module of the present embodiment is provided by combining multiple modules. The above-described single module is referred to as a "module part."

[0237] The above module part may include a dehumidifying member (121) that forms an air contact surface and selectively separates moisture in the air.

[0238] The above dehumidifying member (121) may include a membrane.

[0239] In detail, the dehumidifying member (121) may include a polymer membrane fiber (122) having a hollow fiber structure with excellent selectivity for moisture. The polymer membrane fiber (122) may be cut to a predetermined length and used. The polymer membrane fiber (122) may be referred to as a "hollow fiber membrane."

[0240] The above polymer film fiber (122) can be configured to have a set length (L1) within the dehumidification module (120).

[0241] The above polymer film fiber (122) can be configured to have a diameter (D1) of, for example, about 400 to 420 μm.

[0242] The above polymer film fibers (122) may be provided in multiple strands. The multiple strands of polymer film fibers (122) may be densely arranged and arranged in the circumferential and radial directions.

[0243] The above module part may include a fixing part (123) that supports both sides of the dehumidifying member (121) and a cap (130, 140) that fills the fixing part (123).

[0244] The above-mentioned fixing member (123) may be configured to be filled and hardened in a liquid form inside the cap (130, 140) to fix the position of the dehumidifying member (121). For example, the above-mentioned fixing member (123) may be configured of a urethane or epoxy material.

[0245] The above caps (130, 140) may include a first cap (130) provided at the lower end of the module part and a second cap (140) provided at the upper end of the module part.

[0246] The internal space of the first and second caps (130, 140) can form a space filled with the fixing part (123). The first and second caps (130, 140) can be called "potting caps."

[0247] The above module part may include a support (148) that supports both sides of the dehumidifying member (121). The dehumidifying member (121) may be placed in the space formed by the support (148) and the first cap (130) and the second cap (140).

[0248] The first cap (130) may include a bottom portion (130a) supported on the upper portion (212) of the second housing (210). A through opening (130b) communicating with the through hole (125) of the dehumidifying module (120) may be formed in the center of the bottom portion (130a).

Through the plurality of connection ports (131, 132, 133, 134), water vapor separated from the first to fourth modules (120a, 120b, 120c, 120d) may be discharged.

[0250] The above discharged water vapor can be introduced into the vacuum pump (230) through the first connecting pipe (235). The first connecting pipe (235) can be connected to the plurality of connecting ports (131, 132, 133, 134).

[0251] Next, referring to FIGS. 13 to 15, a module part according to an embodiment of the present invention may include a module housing (150) that provides an installation space for a dehumidifying member (121) and supports the dehumidifying member (121).

[0252] The above module housing (150) may include a frame part (151, 152, 153) provided at the lower end of the module housing (150) and providing a structure to which the first cap (130) is coupled.

[0253] The above frame part (151, 152, 153) may include a first frame part (151) forming a portion of the outer surface of the lower part of the module part and a second frame part (152) forming a portion of the inner surface of the lower part of the module part.

[0254] The first frame part (151) and the second frame part (152) may have the shape of an arc extending in the circumferential direction. The circumferential length of the first frame part (151) may be formed to be longer than the circumferential length of the second frame part (152).

[0255] The above frame part (151, 152, 153) may include a third frame part (153) connecting an end of the first frame part (151) and an end of the second frame part (152).

[0256] The third frame part (153) extends in the radial direction of the module part, and a pair is provided to connect both ends of the first and second frame parts (151, 152).

[0257] The lower part of the dehumidifying member (1231) can be accommodated in the internal space formed by the above frame parts (151, 152, 153).

[0258] The lower part of the above frame part (151, 152, 153) is open, and the open lower part can be shielded by the first cap (130).

[0259] The space defined by the above frame parts (151, 152, 153) and the first cap (130) can form a first potting space in which the fixing part (123) is provided as a potting liquid.

[0260] The above module housing (150) may include a second cap (140) provided at the upper end of the module housing (150). The second cap (140) may include first to fourth parts (141, 142, 143, 144).

[0261] The above first part (141) has a configuration corresponding to the above first frame part (151) and can form a part of the outer surface of the upper part of the above module part.

[0262] The above second part (142) has a configuration corresponding to the second frame part (152) and can form a part of the inner surface of the upper part of the module part.

[0263] The first part (141) and the second part (142) may have the shape of an arc extending in the circumferential direction. The circumferential length of the first part (141) may be formed to be longer than the circumferential length of the second part (142).

[0264] The third part (143) above has a configuration corresponding to the third frame part (153), and may include a third part (143) connecting an end of the first part (141) and an end of the second part (142).

[0265] The third part (143) extends in the radial direction of the module part, and a pair is provided to connect both ends of the first and second parts (141, 142).

[0266] The fourth part (144) may constitute the closed top of the module part. The fourth part (144) may constitute one surface that supports the fixing part (123) when the fixing part (123) is filled. The fourth part (144) may be integrally formed with the module housing (150).

[0267] The upper part of the dehumidifying member (1231) can be accommodated in the internal space formed by the above 1st to 4th parts (141, 142, 143, 144).

[0268] The space defined by the above 1st to 4th parts (141, 142, 143, 144) can form a second potting space in which the fixed part (123) is provided as a potting liquid.

[0269] In summary, the lower part of the module housing (150) may be provided with first to third frame parts (151, 152, 153) and a separate first cap (130) may be configured to be coupled to the first to third frame parts (151, 152, 153).

[0270] On the other hand, the upper part of the module housing (150) may be provided with the first to third parts (141, 142, 143) and the fourth part (144) integrally to form the second cap (140). However, unlike this, the upper part of the module housing (150) may also be configured in the same manner as the lower part of the module housing (150), such that the first to third frame parts are provided and a separate second cap (140) is coupled thereto.

[0271] The above module housing (150) may include supports (148a, 148b) that support both ends of the support member (121). The supports (148a, 148b) may include a first support (148a) that supports one end of the support member (121) and a second support (148b) that supports the other end.

[0272] The first and second supports (148a, 148b) can extend in the vertical direction to connect the third frame part (153) of the lower part of the module part and the third part (143) of the upper part of the module part.

[0273] The space between the radially outermost ends of the first and second supports (148a, 148b) and the space between the radially innermost ends are open, and the open space can form an opening (145). Through the opening (145), air can flow radially inwardly of the module part.

[0274] The above module housing (150) may further include a separation guide (146) provided in an area corresponding to the lower and upper portions of the dehumidifying member (121) to separate the installation space of the dehumidifying member (121) into a first space and a second space.

[0275] The above separation guide (146) can form a circle around the center of the dehumidifying module so that the flow speed of air flowing into the dehumidifying module (120) can be formed uniformly.

[0276] The above separation guide (146) may include a first separation guide (146a) provided in an area corresponding to the lower end of the dehumidifying member (121) and a second separation guide (146b) provided in an area corresponding to the upper end of the dehumidifying member (121).

[0277] The above first separation guide (146a) has a length extending in the circumferential direction, and both ends of the above first separation guide (146a) can be connected to a pair of third frame parts (153).

[0278] The center of curvature of the first separation guide (146a), the center of curvature of the first frame part (151), and the center of curvature of the second frame part (152) may coincide.

[0279] The above first separation guide (146a) can separate the internal space of the frame part (151, 152, 153) into a first space (157a) and a second space (157b). The first space (157a) is formed on the radially outer side of the second space (157b) and can be formed to surround the second space (157b).

[0280] The second separation guide (146b) has a length extending in the circumferential direction, and both ends of the second separation guide (146b) can be connected to a pair of third parts (143).

[0281] The center of curvature of the second separation guide (146b), the center of curvature of the first part (141), and the center of curvature of the second part (142) may coincide.

[0282] The second separation guide (146b) can separate the internal space of the first to fourth parts (141, 142, 143, 144) into a first space (147a) and a second space (147b). The first space (147a) is formed on the radially outer side of the second space (147b) and can be formed to surround the second space (147b).

[0283] The first space (157a) at the bottom of the module part and the first space (147a) at the top of the module part are aligned in the vertical direction, and the second space (157b) at the bottom of the module part and the second space (147b) at the top of the module part can be aligned in the vertical direction.

[0284] Among the plurality of strands (122) of the polymer film fibers (122) constituting the above dehumidifying member (121), a certain amount of strands may be placed in the first space (157a, 147b) and another certain amount of strands may be placed in the second space (157b, 147b).

[0285] The amount or density of the polymer film fibers (122) provided in the first space (157a, 147a) may be formed to be greater than the amount or density of the polymer film fibers (122) provided in the second space (157b, 147b).

[0286] Since the air flows radially inward from the outer surface of the dehumidifying module (120), it first passes through the dehumidifying member (121) arranged in the first space (157a, 147a) and then passes through the dehumidifying member (121) arranged in the second space (157b, 147b).

[0287] Accordingly, during the dehumidification process, the moisture content (water vapor partial pressure) of the air passing through the first space (157a, 147a) may be greater than the moisture content of the air passing through the second space (157b, 147b). To reflect this, the amount of the dehumidifying member (121) arranged in the first space (157a, 147a) may be configured to be greater than the amount of the dehumidifying member (121) arranged in the second space (157b, 147b).

[0288] In detail, a plurality of first polymer film fibers (122a) having a first amount (or a first density) may be arranged in the first space (157a, 147a), and a plurality of second polymer film fibers (122b) having a second amount (or a second density) may be arranged in the second space (157b, 147b). The first amount (or the first density) may be greater than the second amount (or the second density).

[0289] The upper and lower ends of the first polymer film fiber (122a) may be fixed by a fixing member (123). The upper and lower ends of the second polymer film fiber (122b) may be fixed by a fixing member (123). The fixing member (123) may be provided as a potting solution and may be provided after being hardened.

[0290] The above separation guide (146a, 146b) may be provided so as not to completely separate the first space (157a, 147a) and the second space (157b, 147b) so as to allow the flow of potting liquid between the first space (157a, 147a) and the second space (157b, 147b).

[0291] In detail, the second cap (140) provided on the upper part of the module part will be described with reference to FIG. 15.

[0292] The upper part of the second separation guide (146b) and the fourth part (143) can be spaced apart by a first distance (△). Through the spaced apart space, the potting liquid can flow from the first space to the second space, or from the second space to the first space.

[0293] The lower part of the second separation guide (146b) and the lower part of the third part (143) can be spaced apart by a second distance (△). Through the spaced apart space, the potting liquid can flow from the first space to the second space, or from the second space to the first space.

[0294] By this configuration, even if the potting liquid is poured into either the first space or the second space, it can flow evenly into and fill the first and second spaces.

[0295] FIG. 15 describes the configuration of the second separation guide (146b) provided on the second cap (140) side, but the same configuration can also be applied to the first separation guide (146a), the frame parts (151, 152, 153), and the structure of the first cap (130).

[0296] That is, the lower part of the first separation guide (146a) may be spaced apart from the first cap (130) by a first distance, and the upper part of the first separation guide (146a) may be spaced apart from the upper part of the third frame part (153) by a second distance.

[0297] Figures 16 to 20 are drawings showing a manufacturing process of a dehumidifying module, and Figure 21 is a flow chart showing a method for manufacturing a dehumidifying module according to an embodiment of the present invention.

[0298] Referring to FIGS. 16 to 21, a module housing (150) is prepared, the module housing (150) is positioned so that the second cap (140) faces downward, and a polymer membrane fiber (122) is placed (S11, S12).

[0299] In detail, as shown in Fig. 16, the module housing (150) is placed so that the second cap (140) forms the bottom and the frame part (151, 152, 153) forms the top.

[0300] When the above dehumidifying module (120) is installed in the dehumidifier (10), the second cap (140) forms the upper part of the dehumidifying module (120), but in order to first form the fixing part (123) on the side of the second cap (140), the module housing (150) can be placed as shown in FIG. 16.

[0301] The polymer film fiber (122) can be placed inside the module housing (150) so that the polymer film fiber (122) is positioned in the first space (157a, 147a) and the second space (157b, 147b).

[0302] As described above, the amount or density of the first polymer film fiber (122a) disposed in the first space (157a, 147a) may be greater than the amount or density of the second polymer film fiber (122b) disposed in the second space (157b, 147b).

[0303] The lower end of the first polymer film fiber (122a) and the lower end of the second polymer film fiber (122b) can be located in the internal space of the second cap (140).

[0304] The upper part of the first polymer film fiber (122a) and the upper part of the second polymer film fiber (122b) can protrude upward from the frame part (151, 152, 153).

[0305] For example, as shown in FIG. 17, the upper part of the first polymer film fiber (122a) and the upper part of the second polymer film fiber (122b) may be at a position higher than the frame part (151, 152, 153) by a first height (△).

[0306] A portion of the fiber (122a, 122b) protruding from the above frame part (151, 152, 153) by the first height (△) can form a protrusion (122c).

[0307] Among the above frame parts (151, 152, 153), the front end of the first frame part (151) may include a first flange (151a) protruding in the circumferential direction. The first flange (151a) may include a coupling surface (contact surface) with which the first cap (130) is coupled or comes into contact.

[0308] A process for providing a first fixing part (123a) for fixing the polymer film fiber (122) to the internal space of the second cap (140) can be performed. In detail, a first potting liquid can be injected into the internal space of the second cap (140) and waited for it to harden (S13).

[0309] When the first potting liquid is hardened, a first fixing part (123a, see FIG. 20) is formed inside the second cap (140) to fix one end of the polymer film fiber (122). The first fixing part (123a) may be provided in the space between a plurality of polymer film fibers (122).

[0310] The above first fixed part (123a) may be called a “first potting part.”

[0311] The module housing (150) can be positioned so that the above frame parts (151, 152, 153) face downward. That is, the module housing (150) in the state of FIG. 17 can be flipped upside down and positioned as in FIG. 18.

[0312] A first cap (130) can be coupled to the above frame parts (151, 152, 153). The first cap (130) can include a second flange (130b) protruding in the circumferential direction. When the first cap (130) is coupled to the frame part, the second flange (130b) can come into contact with the first flange (151a) of the first frame part (151) (S14).

[0313] A process for providing a second fixing part (123b) for fixing the polymer film fiber (122) to the internal space of the first cap (130) can be performed. In detail, a second potting liquid can be injected into the internal space of the first cap (130) and waited for it to harden (S15).

[0314] When the second potting liquid is hardened, a second fixing part (123b, see FIG. 20) is formed inside the first cap (130) to fix the other end of the polymer film fiber (122). The second fixing part (123b) may be provided in the space between a plurality of polymer film fibers (122).

[0315] The above second fixing unit (123b) may be called a “second potting unit.”

[0316] The first cap (130) can be separated from the frame part, and a portion of the polymer film fiber (122) and a portion of the second fixing part (123b) can be cut horizontally to the lower end of the frame part (S16).

[0317] Then, the first cap (130) can be reassembled and a connection port (131 to 134) can be mounted on the first cap (130) (S17).

[0318] When the first cap (130) is reassembled after the above cutting, a space (130c) can be formed inside the first cap (130), as shown in FIG. 20.

[0319] The above space (130c) forms a space where moisture separated from the dehumidifying member (121) gathers, and the moisture in the space (130c) can be discharged from the dehumidifying module (120) through the connection ports (131 to 134).

[0320] A single module part can be manufactured in this manner. A plurality of module parts can be manufactured and combined to produce a dehumidifying module (120) as shown in FIG. 11. The plurality of module parts can be joined in a circumferential direction. For example, the plurality of module parts can be joined using an adhesive (S18).

[0321] Another embodiment is proposed.

[0322] In the embodiment described above, it is described that a dehumidifying member is provided for each module part and a plurality of module parts are combined to form a dehumidifying module.

[0323] However, in contrast, a dehumidifying member may be provided in one module part and an air purifying member capable of selectively removing or releasing a specific gas may be provided in another module part, and these may be combined to form a dehumidifying module.

[0324] That is, by providing a variety of materials for the dehumidification module, it can perform functions such as air purification or supply of a specific gas in addition to dehumidification.

[0325] Figure 22 is a drawing showing the appearance of air flow and moisture flow in a dehumidifier according to an embodiment of the present invention.

[0326] Referring to Fig. 22, when the fan (160) is driven, air can be drawn into the interior of the dehumidifier (10) through the suction portion (112). Corresponding to the suction portion (112) formed in the circumferential direction, air can be sucked into the center of the interior of the dehumidifier in the circumferential direction.

[0327] Air passes through a dehumidifying module (120) located inside the suction section (112), and moisture (water vapor) in the air can be separated. At this time, moisture can permeate the hollow fiber membrane of the dehumidifying module (120) due to the partial pressure difference of the water vapor.

[0328] The air from which the moisture has been separated flows through the through hole (125) of the dehumidifying module (120) and can flow axially (upward) toward the suction side of the fan (160).

[0329] The air passing through the fan (160) passes through the air guide device (170) and can be discharged to the outside of the dehumidifier through the discharge device (190).

[0330] The separated moisture can be discharged downward from the dehumidifying module (120) and introduced into the vacuum pump (230) through the first connecting pipe (235).

[0331] When the vacuum pump (230) is driven, a vacuum of about 0.2 Bar is maintained at the inlet side of the vacuum pump (230), and the pressure at the outlet side of the vacuum pump (230) increases while the pressure relief valve (240) is closed, so that high pressure can be applied. In addition, when the high pressure becomes higher than the reference pressure, the pressure relief valve (240) can be opened.

[0332] The air compressed at high pressure by the vacuum pump (230) contains a large amount of moisture that has changed into a liquid phase, and the air containing the moisture can be separated into moisture while passing through the moisture separator (260). That is, the water vapor partial pressure reaches the saturated water vapor pressure, and the moisture becomes condensate and can be collected as water. In addition, the separated moisture can be stored by flowing into the water tank (250) located below the moisture separator (260).

[0333] The air from which the moisture has been separated passes through the pressure relief valve (240) and can be introduced into the through hole (125) of the dehumidifying module (120) through the discharge port (217). The air in the through hole (125) passes through the fan (150) and the air guide device (170) and can be discharged to the outside of the dehumidifier through the discharge device (190).

[0334] Meanwhile, when the pressure acting on the pressure relief valve (240) becomes lower than the reference pressure again, the pressure relief valve (240) can be closed again.

[0335] A dehumidifying module according to an embodiment of the present invention comprises an outer circumferential surface formed in a circumferential direction and an inner circumferential surface defined by a through hole, such that air introduced into the outer circumferential surface flows toward the inner circumferential surface, and air dehumidified by a dehumidifying member can be easily discharged through the through hole. Therefore, the dehumidifying module has remarkable industrial applicability.
