Description

dehumidifier

[0001] The present invention relates to a dehumidifier.

[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 moisture contained in the air through heat exchange, and discharging the dehumidified air into the desired space.

[0003] The above dehumidifier removes 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 heat to the surrounding air.

[0005] That is, the air passing through the heat exchanger exchanges heat with the refrigerant as it passes through the evaporator, thereby lowering its humidity, and the air with reduced humidity exchanges heat with the refrigerant as it passes through the condenser, thereby undergoing a drying process.

[0006] 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.

[0007] In the process of dehumidified air being discharged through the discharge unit, it is necessary to improve discharge performance and prevent excessive noise from being generated.

[0008] The purpose of the present invention is to provide a dehumidifier capable of increasing the airflow velocity and improving the discharge performance by generating a concentrated airflow discharged from a fan.

[0009] The present invention aims to provide a dehumidifier having a circular or oval discharge portion having a distance equal or similar from the center of the discharge portion to the edge of the discharge portion in order to reduce a dead zone in the discharge portion.

[0010] The purpose of the present invention is to provide a dehumidifier capable of lowering the flow resistance and reducing noise generated by the flow resistance by improving the configuration of a fan and a fan housing and the arrangement thereof.

[0011] The purpose of the present invention is to provide a dehumidifier capable of improving the discharge performance of a fan by forming the discharge side passage of the fan housing to be larger than the suction side passage.

[0012] The present invention aims to provide a dehumidifier capable of improving the heat exchange efficiency and fluidity of air by arranging the heat exchanger closer to the discharge-side passage of the fan housing and arranging the center of the discharge portion and the center of the discharge-side passage adjacent to each other.

[0013] The purpose of the present invention is to provide a dehumidifier that improves fan suction efficiency and achieves compact component arrangement by eccentrically arranging the discharge portion of the dehumidifier to the side of the fan and arranging the heat exchanger adjacent to the rear of the fan.

[0014] The purpose of the present invention is to provide a dehumidifier in which space utilization can be improved by arranging the heat exchanger to overlap the discharge portion in the vertical direction, thereby utilizing the upper space of the heat exchanger as an air discharge space.

[0015] The purpose of the present invention is to provide a dehumidifier that improves space utilization by positioning a piping portion connected to a heat exchanger on the side of the heat exchanger and arranging the piping portion and the discharge portion to overlap in the vertical direction.

[0016] The purpose of the present invention is to provide a dehumidifier in which a heat exchanger and a fan overlap with respect to a discharge portion and each distance from the heat exchanger and the fan to the discharge portion is formed short to reduce loss of discharged flow.

[0017] The present invention aims to provide a dehumidifier including a chamfer portion extending upwardly in an inclined manner so that the area of ​​the discharge portion can be increased in the overlapping section.

[0018] The purpose of the present invention is to provide a dehumidifier that can efficiently utilize the space on the side of a heat exchanger by providing a support plate that supports both ends of a heat exchanger and providing an installation space for a pipe connected to the heat exchanger on the outside of the support plate.

[0020] A dehumidifier according to an embodiment of the present invention may include a fan and a scroll housing that sucks in air in an axial direction and discharges it in a radial direction.

[0021] In order for the airflow discharged from the fan to be concentrated and discharged through the discharge portion, the center of the discharge part of the scroll housing and the center of the discharge portion may be arranged adjacent to each other or on the same center line.

[0028] The above scroll housing includes a cut-off portion forming a boundary between the suction side and the discharge side of the fan, and a vertical center line passing through the center of the cut-off portion can pass through a first area of ​​the upper surface.

[0029] A dehumidifier according to an embodiment of the present invention includes a fan housing forming an intake port and a heat exchanger positioned adjacent to the intake port, wherein the heat exchanger and the discharge port of the dehumidifier may be positioned to overlap each other in a vertical direction. Accordingly, the upper space of the heat exchanger can be utilized as an air discharge space.

[0030] The upper part of the heat exchanger and the upper part of the discharge part are arranged to overlap in the vertical direction, and a chamfer part extending obliquely from the upper part of the heat exchanger toward the upper part of the discharge part can be included to increase the area of ​​the discharge part in the direction of air flow.

[0031] Support plates are provided at both ends of the heat exchanger to support the sides of the heat exchanger, thereby preventing air passing through the heat exchanger from being sucked into the intake of the fan housing and being bypassed to the outside.

[0032] In one aspect of the present invention, a dehumidifier may include a body having a rear portion where an intake portion is formed, a front portion facing the rear portion, an upper portion where an exhaust portion is formed, and first and second side portions connecting the rear portion and the front portion.

[0033] The above dehumidifier may include a heat exchanger provided inside the main body and exchanging heat with air sucked in through the suction unit.

[0034] The dehumidifier may be disposed on the outlet side of the heat exchanger and may include a fan housing having a fan that axially sucks in air passing through the heat exchanger and radially discharges it, and a discharge part that accommodates the fan and is connected to the discharge part.

[0035] The discharge portion may be arranged to be eccentric laterally with respect to the center of the upper surface portion, and may include a first overlap area (A1) that overlaps vertically with at least a portion of the heat exchanger, and a second overlap area (A2) that overlaps vertically with at least a portion of the fan.

[0036] The above heat exchanger is spaced a set distance to the rear of the fan housing, and the first overlap area (A1) and the second overlap area (A2) can be formed in the front-back direction of the discharge portion.

[0037] The above scroll portion is formed along the outer periphery of the fan and includes a suction-side flow path and a discharge-side flow path that are divided based on the center of the fan, and the first overlap area (A1) and the second overlap area (A2) can overlap the discharge-side flow path.

[0038] The heat exchanger has a first width in the left-right direction to cover the intake of the fan housing, and an installation space for installing a piping part connected to the heat exchanger can be formed on the side of the heat exchanger.

[0039] The above discharge portion may further include a third overlap area (A3) that overlaps the installation space in the vertical direction.

[0040] The fan housing may include an orifice forming an intake for air intake and a support plate protruding from the orifice in a direction toward the heat exchanger and extending along an edge of the heat exchanger.

[0041] The above support plate includes an upper support plate provided on the top of the heat exchanger, and the upper support plate may have a front-back length formed longer than the front-back length of the heat exchanger so as to cover the upper surface of the heat exchanger.

[0042] The upper support plate may be positioned lower than the discharge part, and the fan housing may include a chamfer portion extending obliquely from the upper support plate toward the discharge part.

[0043] The above chamfered portion may include a chamfered lower portion that defines the smallest cross-sectional area of ​​the internal passages of the chamfered portion and is connected to the upper support plate, and a chamfered upper portion that defines the largest cross-sectional area of ​​the internal passages of the chamfered portion and is connected to the discharge part.

[0044] The above support plate includes first and second side support plates, and the heat exchanger is supported between the first and second side support plates and may have a first width (W1) in the left and right direction to cover the intake of the fan housing.

[0045] The first side support plate may be arranged adjacent to the suction side flow path around the fan, and the second side support plate may be arranged adjacent to the discharge side flow path around the fan.

[0046] The shortest distance (△S2) between the second side support plate and the outer surface of the suction port can be formed to be greater than the shortest distance (△S1) between the first side support plate and the outer surface of the suction port.

[0047] The above discharge portion may be formed at the upper end of the above discharge part.

[0048] From another perspective, the heat exchanger of the dehumidifier may be positioned at the rear of the fan housing, and the fan housing may include a chamfered portion extending obliquely from the upper side of the heat exchanger toward the rear and connected to the discharge portion so that at least a portion of the discharge portion and the heat exchanger may overlap.

[0049] Among the above heat exchangers, the portion overlapping the discharge part may be eccentric laterally with respect to the center of the upper surface.

[0050] The discharge part may be positioned on the upper side of the fan so that at least a portion of the fan may overlap with the discharge part.

[0051] Among the above fans, the portion overlapping with the discharge part may be eccentric laterally with respect to the center of the upper surface.

[0052] The above discharge portion and the above discharge part may be configured in a circular shape by being eccentric laterally with respect to the center of the upper surface portion.

[0053] According to an embodiment of the present invention, the airflow discharged from the fan can be concentrated to increase the airflow velocity and improve discharge performance.

[0054] According to an embodiment of the present invention, a circular or oval discharge portion is provided with a distance equal or similar from the center of the discharge portion to the edge of the discharge portion, so that a dead zone in the discharge portion can be reduced.

[0055] According to an embodiment of the present invention, the configuration of the fan and the fan housing and the arrangement thereof can be improved to lower the euro resistance and reduce noise generated by the euro resistance.

[0056] According to an embodiment of the present invention, the discharge performance of the fan can be improved by forming the discharge side passage of the fan housing to be larger than the suction side passage.

[0057] According to an embodiment of the present invention, the heat exchanger is arranged closer to the discharge-side passage of the fan housing and the center of the discharge portion and the center of the discharge-side passage are arranged adjacent to each other, thereby improving the heat exchange efficiency and fluidity performance of the air.

[0058] According to an embodiment of the present invention, by eccentrically positioning the discharge portion of the dehumidifier to the side of the fan and arranging the heat exchanger adjacent to the rear of the fan, the width in the front-to-rear direction of the dehumidifier can be reduced, thereby implementing a compact dehumidifier and improving the fan suction efficiency.

[0059] According to an embodiment of the present invention, by arranging the heat exchanger to overlap the discharge portion in the vertical direction, the upper space of the heat exchanger can be utilized as an air discharge space, thereby improving space utilization.

[0060] According to an embodiment of the present invention, space utilization can be improved by positioning a piping part connected to a heat exchanger on the side of the heat exchanger and arranging the piping part and the discharge part to overlap in the vertical direction.

[0061] According to an embodiment of the present invention, the heat exchanger and the fan overlap with respect to the discharge portion, and the distances from the heat exchanger and the fan to the discharge portion are formed relatively close, so that flow loss can be reduced.

[0062] According to an embodiment of the present invention, a chamfer portion extending upwardly in an inclined manner in the overlapping section is formed, thereby producing an effect in which the area of ​​the discharge portion increases in the direction of air flow.

[0063] According to an embodiment of the present invention, a support plate supporting both ends of a heat exchanger is provided, and an installation space for a pipe connected to the heat exchanger is provided on the outside of the support plate, so that the space on the side of the heat exchanger can be efficiently utilized.

[0092] Additionally, terms such as first, second, A, B, (a), (b), etc. may be used to describe components of embodiments of the present invention. These terms are only intended to distinguish the components from other components, and the nature, order, or sequence of the components are not limited by the terms. When it is described that a component is "connected," "coupled," or "connected" to another component, it should be understood that the component may be directly connected or connected to the other component, but another component may also be "connected," "coupled," or "connected" between each component.

[0094] Referring to FIGS. 1 to 4, a dehumidifier (10) according to an embodiment of the present invention may have a slim shape having a relatively thin thickness in the front-back direction.

[0095] The above dehumidifier (10) has a three-dimensional shape and can have a length (L1) in a first direction, a length (L2) in a second direction, and a length (L3) in a third direction. The directions are defined.

[0096] The above first direction is the direction in which the water tank (130), compressor (161), and electric device (170) described later are arranged, and may correspond to the left-right direction (x-axis direction) of the dehumidifier. In addition, the above first direction may be understood as the direction from the first side portion (103) described later toward the second side portion (104).

[0097] The above second direction is the direction in which air passing through the fan (230) described later is discharged through the discharge unit (140), and can correspond to the up-down direction (y-axis direction) of the dehumidifier.

[0098] The third direction above is the direction in which the suction unit (112), heat exchanger (180), and fan (230) described later are arranged, and can correspond to the front-back direction (z-axis direction) of the dehumidifier.

[0099] For example, when defining the length (L1) in the first direction, the length (L2) in the second direction, and the length (L3) in the third direction of the dehumidifier (10), the length (L2) in the second direction may be greater than the length (L1) in the first direction, and the length (L1) in the first direction may be greater than the length (L3) in the third direction.

[0100] The above dehumidifier (10) may include a main body (100) that forms an exterior and accommodates a number of components for discharging dehumidified air. The main body (100) may include a first case (110) and a second case (120).

[0101] The outer surface of the main body (100) can be defined by the first and second cases (110, 120). In detail, the main body (100) can 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 lower portion (106).

[0102] The first case (110) is placed on the upper side of the second case (120), and the first and second cases (110, 120) can be coupled to each other. A fastening mechanism (115) can be provided on the coupling surfaces of the first and second cases (110, 120). For example, the fastening mechanism (115) can include a bracket and a fastening member.

[0103] A fan assembly (200) for generating airflow and a heat exchanger (180) for exchanging air heat can be placed inside the first case (110).

[0104] A compressor (161), a water tank (130), and an electric device (170) can be placed inside the case (120).

[0105] The first and second cases (110, 120) are configured such that the left and right ends extend in a rounded manner with a predetermined curvature, and can improve the aesthetic appeal in terms of design by forming a smooth surface. That is, the first side portion (103) and the second side portion (104) can include smoothly rounded surfaces.

[0106] The curvature of the portion forming the upper surface (105) of the first side portion (103) can be formed to correspond to the curvature of the discharge portion (140) described later.

[0107] The dehumidifier (10) may include a water tank (130) for storing condensed water in the air. The water tank (130) may be detachably provided at the lower portion of the dehumidifier (10). For example, the water tank (130) may be detachably provided at the second case (120).

[0108] The water tank (130) can be separated laterally from the dehumidifier (10). Since the water tank (130) is located at the bottom of the dehumidifier, the weight stability of the dehumidifier is improved, and the risk of water stored in the dehumidifier flowing into internal components of the dehumidifier is reduced.

[0109] When the dehumidifier is in operation, external air is sucked into the rear portion (102) of the dehumidifier (10) and can be discharged through the upper portion (105). The rear portion (102) may be provided with a suction portion (112) for sucking air, and the upper portion (105) may be provided with a discharge portion (140).

[0110] The above suction portion (112) is formed on the rear surface (102) of the first case (110), and the discharge portion (140) may be formed by opening a portion of the upper surface (105) of the first case (110).

[0111] The above discharge portion (140) can guide air passing through the fan (230) to be discharged upward from the dehumidifier. The above discharge portion (140) can be configured to have a width substantially the same as the maximum width of the discharge side flow path of the fan (230).

[0112] For example, the discharge portion (140) may include a circular discharge portion having the width as a diameter.

[0113] The side edge of the upper surface (105) includes a rounded curved portion, and a portion of the outer surface of the circular discharge portion can form a curvature corresponding to the side edge of the upper surface (105).

[0114] The center of curvature of a portion of the outer surface of the above-mentioned circular discharge portion may be formed to be identical to the center of curvature of the side edge of the above-mentioned upper surface portion (105). According to this configuration, a portion of the outer surface of the above-mentioned circular discharge portion may extend parallel to the side edge of the above-mentioned upper surface portion (105).

[0115] The above discharge portion (140) may be formed at a position eccentric to one side with respect to the left-right center of the upper surface portion (105). For example, the above discharge portion (140) may be formed at a position closer to the first side portion (103) among the first and second side portions (103, 104).

[0116] The above discharge unit (140) may be provided with a discharge vane (145) that controls the direction of the discharged air flow. The above discharge vane (145) may be provided to be movable or rotatable.

[0117] Inside the above main body (100), a fluid part in which parts for generating airflow and exchanging heat are arranged and a driving part in which main driving parts and processing parts necessary for the operation of the dehumidifier are arranged can be arranged.

[0118] The above-mentioned fluid part and driving part can be arranged vertically. For example, the fluid part can be arranged above the driving part, and an internal frame (150) can be arranged between the fluid part and the driving part to partition them.

[0119] The above-mentioned fluid part may include a heat exchanger (180) arranged inside the suction part (112) and a fan assembly (200) arranged in front of the heat exchanger (180) and through which air passing through the heat exchanger (180) is sucked.

[0120] The above heat exchanger (180) may include an evaporator (181) and a condenser (183). The evaporator (181) and the condenser (183) may be arranged in parallel in the direction in which air flows, i.e., in the front-back direction.

[0121] The above heat exchanger (180) is placed on the side of the evaporator (181) and the condenser (183) and may further include a piping section (185) that guides the flow of refrigerant entering and exiting the evaporator (181) and the condenser (183).

[0122] The above evaporator (181) is placed between the suction part (112) and the condenser (183), so that air sucked through the suction part (112) can be cooled by first passing through the evaporator (181) and then heated by passing through the condenser (183).

[0123] As the air passes through the evaporator (181) and is cooled, the moisture contained in the air condenses to form condensate, and the air can be dehumidified. The condensate can be stored in a water tank (130).

[0124] The dehumidified air is heated as it passes through the condenser (183) and can be sucked into the fan assembly (200). The air that passes through the fan assembly (200) can be discharged through the discharge portion (140) provided at the upper end of the fan assembly (200).

[0125] The above driving part may include a water tank (130) that stores condensate generated in the evaporator (181). For example, the water tank (130) may be positioned so as to be exposed to the second side portion (104) of the main body (100). A user may withdraw the water tank (130) to the side of the second side portion (104).

[0126] The above driving part may further include a compressor (161) that compresses refrigerant to drive a refrigeration cycle. The refrigerant compressed in the compressor (161) may be introduced into the condenser (183) through the pipe (185).

[0127] The above pipe section (185) is connected to the outlet port of the compressor (161) and can be connected to the condenser (183) by passing through or bypassing the inner frame (150).

[0128] The above driving part may further include an electric device (170) in which electric components of the dehumidifier are provided.

[0129] The water tank (130), the compressor (161) and the electric device (170) may be arranged in the left-right direction, for example, in the direction from the second side portion (104) to the first side portion (103).

[0130] The above inner frame (150) may include a partition plate (151) that divides the inner space of the main body (100) into upper and lower parts to separate the fluid part and the driving part.

[0131] The inner frame (150) may further include a plurality of partition walls (153, 155) extending from the partition plate (151) toward the driving part and separating the accommodation space of the components of the driving part.

[0132] The above-described plurality of partition walls (153, 155) may include a first partition wall (153) for defining a receiving space of the water tank (130). The first partition wall (153) may extend downward from the partition plate (151) and be supported on the bottom surface (106). The main body (100), the first partition wall (153), and the partition plate (151) may define a receiving space of the water tank (130).

[0133] The above-described plurality of bulkheads (153, 155) may further include a second bulkhead (155) for defining a space for accommodating the compressor (161) and the electrical device (170). The second bulkhead (155) may extend downward from the partition plate (151) and be supported on the bottom surface (106). The second bulkhead (155) may be arranged to be spaced laterally from the first bulkhead (153).

[0134] The first bulkhead (153), the second bulkhead (155), and the partition plate (151) can define a space for accommodating the water tank (130). In addition, the main body (100), the second bulkhead (155), and the partition plate (151) can define a space for accommodating the electric device (170).

[0135] Referring to Fig. 4, when looking down at the dehumidifier (10) from above, the discharge portion (140) can be eccentric to one side from the left-right center (C1) of the upper surface (105).

[0136] In detail, when defining a center line (ℓc) extending from the left-right center (C1) in the front-back direction, the center line (ℓc) can divide the upper surface (105) into a first region where the discharge portion (140) is located and a second region on the opposite side.

[0137] That is, the discharge portion (140) may be formed in the first region among the first and second regions defined on both sides with respect to the center of the upper surface portion (105). The discharge portion (140) may be positioned adjacent to the lateral edge of the upper surface portion (105), and both ends of the discharge portion (140) may be positioned in the first region.

[0248] In this way, by forming rounded first and second discharge parts (216, 226) corresponding to the circular discharge part and arranging the cut-off part (215) at one end of the rounded first and second discharge parts (216, 226), the discharge area of ​​air can be increased and re-intake into the fan can be prevented.

[0249] Referring to FIGS. 13 and 14, the heat exchanger (180) may be positioned adjacent to the outside of the intake port (223) of the fan housing.

[0250] Since the left-right width (W1, first width) of the heat exchanger (180) is formed to be larger than the diameter (D1) of the fan suction port (223), the heat exchanger (180) can be arranged to cover the fan suction port (223).

[0251] The left-right width (W1) of the above heat exchanger (180) can be understood as the distance between the first side support plate (229a) and the second side support plate (229b).

[0252] The shortest distance (△S1) between the fan suction port (223) and the first side support plate (229a) can be formed to be smaller than the shortest distance (△S1) between the fan suction port (223) and the second side support plate (229b).

[0253] Accordingly, the center of the heat exchanger (180) can be eccentrically arranged closer to the discharge-side flow path (205b) than to the suction-side flow path (205a). That is, since the heat exchanger (180) is arranged closer to the discharge-side flow path (205b) with a large flow path width, the flow performance can be improved and the heat exchange area can be increased.

[0254] The above orifice (220) may further include a chamfer portion (227) that extends from the upper support plate (228) toward the second discharge part (226) in a direction that increases the discharge area of ​​air.

[0255] The above chamfered portion (227) may have a flow path cross-sectional area that expands upward so that air discharged through the discharge side flow path (205b) can expand and be discharged toward the discharge portion (140).

[0256] For example, the chamfer portion (227) may be configured to extend upward in a funnel shape from the lower end of the chamfer portion (227).

[0257] In detail, the chamfer portion (227) may include a chamfer lower portion (227a) defining the smallest flow path cross-sectional area among the internal flow paths of the chamfer portion (227) and a chamfer upper portion (227b) defining the largest flow path cross-sectional area among the internal flow paths of the chamfer portion (227).

[0258] The above chamfer portion (227) can extend from the chamfer lower portion (227a) toward the chamfer upper portion (227b) at a first angle (α1) with respect to the vertical reference line.

[0259] The above chamfer portion (227) may be configured to have an extended shape to increase the cross-sectional area of ​​the flow path from the upper support plate (228) toward the second discharge part (226).

[0260] To this end, the chamfer lower portion (227a) of the chamfer portion (227) is formed at a position corresponding to the upper support plate (228), and can be connected to the upper support plate (228), for example.

[0261] The chamfer upper portion (227b) of the above chamfer portion (227) can be connected to the second discharge part (226). That is, the flow path cross-sectional area at the chamfer upper portion (227b) can correspond to the flow path cross-sectional area of ​​the second discharge part (226). By means of such a configuration, there is an advantage in that the discharge area of ​​the discharged air can be increased.

[0262] The front-to-rear width (W2, second width) of the heat exchanger (180) may be formed to be longer than the front-to-rear length of the upper support plate (228). Accordingly, stable support of the heat exchanger (180) can be achieved.

[0263] The above discharge part (216, 226) may be located on the upper side of the heat exchanger (180).

[0264] The above discharge part (216, 226) and the heat exchanger (180) can be arranged in positions where they overlap in the vertical direction. With this configuration, the upper space of the heat exchanger (180) can be utilized as a discharge space, thereby improving space utilization.

[0265] The front-to-rear width (W2) of the heat exchanger (180) may be formed to be smaller than half the diameter (D3) of the discharge part (216, 226). In this way, a compact component arrangement can be achieved by arranging the heat exchanger (180) adjacent to the intake port (223) of the fan housing and reducing the front-to-rear width of the heat exchanger (180).

And, Fig. 18 is a cross-sectional view taken along a front-back extension line (18-18) passing through the center of the discharge portion (140).

[0268] Referring to FIGS. 15 to 20, a space (hereinafter, installation space) in which the main components of the dehumidifier are installed can be formed inside the main body (100) according to an embodiment of the present invention.

[0269] A water tank (130), a compressor (161), and an electric device (170) may be installed at the bottom of the above installation space. The compressor (161) is located between the water tank (130) and the electric device (170), and the vertical center line passing through the center of the fan (230) may pass through the compressor water receiving space (156).

[0270] The height of the compressor (161) may be formed to be smaller than the height of the water tank (130) and the height of the electric device (170).

[0271] In the structure of the fan housing (201) including the scroll part (213), the central part of the lower part of the fan housing (201) is at the lowest position, so among the water tank (130), compressor (161) and electric device (170), the compressor (161) can be placed at the lower part of the central part of the fan housing (201).

[0272] A fan housing (201) that accommodates a fan (230) may be installed at the upper portion of the above installation space. The axis of the fan (230) faces the front-back direction of the dehumidifier, and air sucked in through the suction portion (112) may be sucked in the axial direction of the fan (230) while moving forward.

[0273] The above fan housing (201) may include a scroll portion (213) whose outer diameter gradually increases in the rotational direction of the fan (230). A fan path (205) may be formed between the fan (230) and the scroll portion (213) through which air passing through the fan (230) flows toward the discharge portion (140).

[0274] The fan (230) may be mounted on the housing body (210). The housing body (210) may include a fan mounting portion (211) on which the fan (230) is mounted. The fan mounting portion (211) may form a portion of the front surface of the housing body (210).

[0275] The above housing body (210) may further include a cut-off portion (215) that forms a boundary between the discharge and re-intake of the air flow of the fan (230). The cut-off portion (215) may be formed to be inclined with respect to a vertical center line passing through the center of the fan (230).

[0276] The above cut-off portion (215) can define the starting point of the fan mileage (205). The distance between the cut-off portion (215) and the fan (230) can correspond to the smallest width of the fan mileage (205).

[0277] The housing body (210) is connected to the fan mounting portion (211) and may further include a discharge guide portion (214) defining a discharge-side flow path among the fan flow paths (205). The discharge guide portion (214) may be formed to be sunken in a direction that increases the width of the discharge-side flow path, for example, forward.

[0278] The above discharge guide portion (214) may include a curved portion that extends in a round shape.

[0279] The above discharge guide portion (214) extends from the fan mounting portion (211), and may include a boundary portion (217) between the fan mounting portion (211) and the discharge guide portion (214) that forms an interface between the fan mounting portion (211) and the discharge guide portion (214).

[0280] The above boundary portion (217) can extend linearly in the vertical direction of the fan housing (201).

[0281] The above cut-off portion (215) may include an end portion (215a) connected to the boundary portion (217). The end portion (215a) may be understood as the end portion of the inclined shape of the cut-off portion (215) that is closest to the discharge guide portion (214).

[0282] The above boundary portion (217) can extend downward from the fan housing (201) starting from the end portion (215a).

[0283] The upper end of the discharge guide portion (214) may correspond to the upper end of the cut-off portion (215). A vane assembly (142) is mounted on the upper end of the discharge guide portion (214), and the discharge vane (145) of the vane assembly (142) can operate to open or close the discharge portion (140).

[0284] Referring to FIGS. 16 and 17, the vertical center line passing through the center of the dehumidifier (10) may pass through the fan motor (237) and may pass through the approximate center of the heat exchanger (180). In addition, the vertical center line and the center of the fan (230) may be eccentric in the left and right directions.

[0285] The above fan housing (201) may include a housing body (210) that accommodates a fan (230) and an orifice (220) coupled to the rear of the housing body (210).

[0286] The above orifice (220) may include an upper support plate (228) that supports the upper end of the heat exchanger (180). The upper support plate (228) may be positioned at a lower position than the upper end where the orifice (220) and the housing body (210) are coupled.

[0287] The front end (180a) of the heat exchanger (180) may be positioned to face the suction port (223) of the fan housing (201). The front end (180a) may be positioned adjacent to the suction port (223).

[0288] For example, the front end (180a) may be spaced apart from the suction port (223) by a set distance (△S3) and may be positioned adjacent to the suction port (223) to a position where it almost comes into contact with the suction port.

[0289] The lower part of the heat exchanger (180) is supported by a support bracket (152d), and an upper support plate (228) can be placed on the upper part of the heat exchanger (180).

[0290] The upper surface of the above heat exchanger (180) can be covered by the upper support plate (228).

[0291] The support plates (228, 229a, 229b) surrounding the corners of the above heat exchanger (180) may function as a blocking plate to prevent air from being bypassed to the outside.

[0292] Referring to FIGS. 18 to 20, the center line in the front-back direction passing through the center of the discharge portion (140) can pass through the heat exchanger (180).

[0293] The center line in the forward-backward direction may be eccentric in the left-right direction with respect to the outermost end of the fan (230) so that the center line in the forward-backward direction does not pass through the fan (230). The outermost end of the fan (230) may be understood as the end closest to the first side portion (103) of the dehumidifier (10).

[0294] A vane assembly (142) may be mounted on the upper side of the fan housing (201). The vane assembly (142) may be coupled to the discharge portion (140).

[0295] The above discharge portion (140) may be located above the heat exchanger (180) and the fan (230).

[0296] The heat exchanger (180) may include a portion that overlaps with the discharge portion (140). A portion of the heat exchanger (180) may form a first overlap area (A1) that overlaps a portion of the discharge portion (140) in the vertical direction.

[0297] The above first overlap area (A1) may correspond to a portion of the discharge side flow path (205b) of the fan housing (201). For example, referring to FIG. 21, the first overlap area (A1) may correspond to a right side of the heat exchanger (180) and a rear side area of ​​the discharge portion (140).

[0298] An extension line (ℓ4) passing vertically through a part of the heat exchanger (180) can pass through a part of the discharge portion (140).

[0299] The fan (230) may include a portion that overlaps with the discharge portion (140). A portion of the fan (230) may form a second overlap area (A2) that overlaps a portion of the discharge portion (140) in the vertical direction.

[0300] The second overlap area (A2) may correspond to the discharge side flow path (205b) of the fan housing (201). For example, based on FIG. 21, the second overlap area (A2) may correspond to the right side of the fan (230) and a front side area of ​​the discharge portion (140).

[0301] An extension line (ℓ5) passing through a part of the fan (230) in the vertical direction can pass through another part of the discharge part (140).

[0302] The above first overlap area (A1) and the second overlap area (A2) can be formed to overlap the upper side of the discharge side flow path (205b) among the fan flow paths (205).

[0303] According to this configuration, the heat exchanger (180) and the fan (230) overlap with respect to the discharge portion (140), and the distance from the heat exchanger (180) and the fan (230) to the discharge portion (140) is formed relatively close, so that flow loss can be reduced.

[0304] Referring to Fig. 20, air flow is described.

[0305] When the fan motor (237) above is driven and the fan (230) rotates, external air can be sucked into the interior of the dehumidifier through the suction part (112). The sucked air can pass through the heat exchanger (180).

[0306] In detail, air is cooled by first passing through the evaporator (181) among the heat exchangers (180), and the condensate generated in this process can fall into the water tank (130) through the drain port (152c) of the heat exchanger support (152a).

[0307] The air passing through the above evaporator (181) can be heated while passing through the condenser (183) located downstream of the evaporator (181). The air passing through the condenser (183) can be sucked in the axial direction of the fan (230) and discharged in the radial direction through the blades (234) of the fan (230).

[0308] The above discharged air can flow and expand in the rotational direction of the fan (230) while passing through the fan path (205) between the scroll part (213) and the fan (230). The air can pass through the expanded path while passing through the discharge guide part (214), and a sufficient flow rate can be secured in this process.

[0309] Air passing through the discharge guide section (214) is prevented from being re-inhaled by the cut-off section (215), and can be easily discharged to the discharge section (140).

[0310] Meanwhile, the area of ​​the discharge-side flow path can be increased by the chamfered portion (227) provided in the orifice (220). The chamfered portion (227) is provided at a position facing the discharge guide portion (214) and can be extended obliquely upward to increase the flow path cross-sectional area.

[0311] According to this configuration, the discharge flow rate can be secured by increasing the area of ​​the discharge side flow path of the fan (230), and concentrated discharge of air can be possible through the discharge part (140) connected to the discharge side flow path.

[0312] FIG. 21 is a top view of a dehumidifier showing the relative positions of a fan, a heat exchanger, and a discharge portion according to an embodiment of the present invention, FIG. 22 is a schematic diagram showing the relative positions of a fan, a heat exchanger, and a discharge portion according to an embodiment of the present invention, FIG. 23a is a drawing showing a dehumidifier according to the prior art in which a slit-shaped discharge portion is formed, and FIG. 23b is a drawing showing a dehumidifier according to the present invention in which a circular discharge portion is formed.

[0313] First, referring to Fig. 21, when looking down at the dehumidifier (10) from above, the heat exchanger (180) and the fan (230) are arranged in the front-back direction, and the discharge portion (140) can be arranged at an eccentric position laterally of the heat exchanger (180) and the fan (230).

[0314] A first center line (ℓc) in the front-back direction passing through the center of the heat exchanger (180) or the upper surface (105), a second center line (ℓ2) in the front-back direction passing through the center of the fan (230), and a third center line (ℓ3) in the front-back direction passing through the center of the discharge portion (140) can be defined.

[0315] The first center line (ℓc), the second center line (ℓ2), and the third center line (ℓ3) may be eccentric with each other. The second center line (ℓ2) may be spaced apart from the first center line (ℓc) by a first distance (S1) in a direction toward the second side portion (104), and the third center line (ℓ3) may be spaced apart from the first center line (ℓc) by a second distance (S2) in a direction toward the first side portion (103).

[0316] The above first center line (ℓc) may be located between the second center line (ℓ2) and the third center line (ℓ3).

[0317] In order for the air discharged from the fan (230) along the scroll section (213) to flow a short distance toward the discharge section (140) and be discharged in a concentrated manner, the center of the discharge section (140) may be positioned closer to the first side section (103) than the outermost end (230a) of the fan (230).

[0318] That is, the distance from the center of the discharge portion (140) to the first side portion (103) may be smaller than the distance from the outermost end (230a) of the fan (230) to the first side portion (103).

[0319] The discharge portion (104) to which the above-mentioned vane assembly (142) is coupled can be formed adjacent to the first side portion (103).

[0320] In detail, the first curved portion (140a) closest to the first side portion (103) among the outer surface of the discharge portion (140) is formed to have a curvature corresponding to the second curved portion (103a) of the first side portion (103), and the first and second curved portions may have the same center of curvature (Cr). In addition, the center of curvature (Cr) may form the center of the discharge portion (140).

[0321] Next, referring to FIG. 22, a first center line (ℓc') in the vertical direction passing through the center of the heat exchanger (180), a second center line (ℓ2') in the vertical direction passing through the center of the fan (230), and a third center line (ℓ3') in the vertical direction passing through the center of the discharge portion (140) can be defined.

[0322] The first center line (ℓc'), the second center line (ℓ2'), and the third center line (ℓ3') may be eccentric with each other.

[0323] The second center line (ℓ2') may be spaced apart from the first center line (ℓc') by a first distance (S1) in a direction toward the second side portion (104), and the third center line (ℓ3') may be spaced apart from the first center line (ℓc') by a second distance (S2) in a direction toward the first side portion (103).

[0324] The above first center line (ℓc') may be located between the second center line (ℓ2') and the third center line (ℓ3').

[0325] The fan path (205) formed in the fan housing (201) may include an upstream path (205a) and a downstream path (205b). The upstream path (205a) may extend from the cut-off portion (215) in the rotational direction of the fan (230).

[0326] The above downstream-side flow path (205b) is formed downstream of the above upstream-side flow path (205a) and can define a discharge-side flow path that guides air to the discharge portion (140).

[0327] The downstream flow path (205b) may be formed on the opposite side of the upstream flow path (205a) with respect to the second center line (ℓ2'). Depending on the configuration of the scroll unit (213), the flow path width (or cross-sectional area) of the downstream flow path (205b) may be larger than the flow path width (or cross-sectional area) of the upstream flow path (205a).

[0328] An installation space (185a) may be formed on the side of the heat exchanger (180) in which a pipe (185) connected to the heat exchanger (180) is placed.

[0329] At least a portion of the discharge portion (140) may be positioned on the upper side of the pipe portion (185). At least a portion of the pipe portion (185) and the discharge portion (140) may overlap in the vertical direction.

[0330] The area of ​​the above discharge portion (140) that overlaps with the pipe portion (185) may be named a third overlap area (A3). The third overlap area may correspond to a rear area of ​​the above discharge portion (140).

[0331] The above third overlap area may correspond to a part of the discharge side flow path (205b) of the fan housing (201).

[0332] According to this configuration, there is an advantage in that the lateral space of the heat exchanger (180) can be utilized as a space for installing a piping section (185) and the upper space of the piping section (185) can be utilized as a discharge space (space efficiency).

[0333] Referring to Fig. 23a, when the discharge portion (140') has a slit structure formed in the horizontal direction of the upper surface of the dehumidifier, the distance between the discharge side flow path of the fan and the two ends of the discharge portion (140') can be formed differently.

[0334] Since air tends to be discharged toward the center of the discharge portion (140'), dead zones (Dz1, Dz2) with little or no discharge of air may be formed in the areas of both ends of the discharge portion (140') located at a relatively long distance from the center of the discharge portion (140').

[0335] Therefore, problems such as difficulty in concentrated air discharge and noise generation in the dead zone area may arise.

[0336] Referring to FIG. 23b, the discharge portion (140) according to the embodiment of the present invention may be formed eccentrically to one side with respect to the center of the upper surface (105) of the dehumidifier.

[0337] The above discharge portion (140) is positioned adjacent to the discharge side flow path of the fan, and the discharge portion (140) forms a circular discharge portion so that the outer surface of the discharge portion (140) has the same distance from the center of the discharge portion, so that concentrated discharge of air can be possible. In addition, the flow rate of the discharged air can be increased.

[0338] According to this configuration, when dehumidifying a specific space or a specific item through a dehumidifier, the dehumidifying performance can be improved through concentrated air discharge.

[0339] For example, installing a dehumidifier next to a laundry drying rack and positioning the outlet toward the laundry allows for a concentrated airflow directed toward the laundry, thereby enabling rapid drying of the laundry.

[0340] FIG. 24 is a cross-sectional view taken along the center of a dehumidifier according to an embodiment of the present invention, FIG. 25a is a schematic diagram showing the internal configuration of a dehumidifier according to the prior art in which a slit-shaped discharge portion is formed, and FIG. 25b is a schematic diagram showing the internal configuration of a dehumidifier according to the present invention in which a circular discharge portion is formed.

[0341] Referring to FIG. 24, the upstream side flow path (205a) and the downstream side flow path (205b) of the fan flow path (205) may be formed on opposite sides with respect to the center of the fan (230).

[0342] The downstream flow path (205b) may extend upward from the side of the fan (230) and be connected to the vane assembly (142). The uppermost end of the downstream flow path (205b) defines the first discharge part (216) of the housing body (210) and the second discharge part (226) of the orifice (220), and the vane assembly (142) may be coupled to the first discharge part (216).

[0343] The flow path width (w1) of the discharge part defined by the first discharge part (216) and the second discharge part (226) can form the maximum width of the downstream flow path (205b).

[0344] A discharge unit (140) may be positioned directly above the discharge part. In addition, the flow path width (w2) of the discharge unit (140) may be substantially the same as the flow path width (w1) of the discharge part (216, 226).

[0345] The center of the above discharge portion (140) can be concentric with the center of the above discharge part (216, 226).

[0346] For example, the discharge portion (140) may be configured as a circular discharge portion, and since the discharge part may have a circular shape, the widths (w1, w2) may each be defined as the diameter of the circle. With this configuration, air passing through the discharge part may be intensively discharged through the discharge portion (140).

[0347] A cut-off portion (215) may be provided at the interface between the downstream flow path (205b) and the upstream flow path (205a) to prevent air discharged through the downstream flow path (205b) from being re-inhaled into the upstream flow path (205a).

[0348] The cut-off portion (215) may include a first end portion (215a) connected to the boundary portion (217) and a second end portion (215b) defining a starting point of the upstream flow path (205a). The cut-off portion (215) may extend from the first end portion (215a) toward the second end portion (215b) at an angle with respect to a vertical reference line.

[0349] Referring to Fig. 25a, since the discharge portion (140') is formed to be elongated in the left-right direction, the airflow discharged from the fan can be formed to slope upward toward the discharge portion. In this process, dead zones (Dz1, Dz2) with little or no airflow can be formed at both ends of the discharge portion.

[0350] In order to discharge air through the discharge portion formed long in the left-right direction, the cut-off portion (215a) of the fan is positioned eccentrically to the left (based on Fig. 25a) from the center of the fan.

[0351] That is, the left end of the discharge portion is positioned furthest from the discharge side flow path of the fan, and the cut-off portion (215a) is positioned in a direction adjacent to the left end in order to discharge air as much as possible to the left end.

[0352] In detail, the vertical center line (ℓ21) passing through the center of the fan (230) may be located between the vertical center line (ℓ41) passing through the center of the cut-off portion (215') and the vertical center line (ℓ31) passing through the center of the discharge portion (140).

[0353] Meanwhile, the width of the discharge portion (140') may be formed to be larger than the width of the discharge part (116') of the fan housing that accommodates the fan (230). Accordingly, the air discharged through the discharge portion (116') flows to the discharge portion (140') with the flow path width expanded, which may cause a problem of reduced flow rate.

[0354] On the other hand, referring to FIG. 25b, the cut-off portion (215) according to the embodiment of the present invention may be positioned eccentrically in the direction from the center of the fan toward the discharge portion (140).

[0355] Since the entire area of ​​the above discharge portion (140) is arranged adjacent to the discharge side flow path of the fan, there is no need to arrange the cut-off portion (215) eccentrically to the left as in Fig. 25a.

[0356] That is, since the cut-off portion (215) is positioned eccentrically to the right from the center of the fan to a position closer to the discharge-side flow path, it is possible to more effectively prevent the discharged airflow from being re-inhaled to the fan side.

[0357] In detail, the vertical center line (ℓ42) passing through the center of the cut-off portion (215) may be located between the vertical center line (ℓ41) passing through the center of the fan (230) and the vertical center line (ℓ32) passing through the center of the discharge portion (140).

[0358] As described above, the width of the discharge portion (140) may be substantially the same as the width of the discharge part (116, 126) of the fan housing. Accordingly, the air discharged through the discharge part (116, 126) flows to the discharge portion (140) while maintaining the flow path width, so that the flow velocity may not decrease.

[0359] Ultimately, the dehumidifying performance of the drying target can be improved. This is similar to the principle of quickly drying hair by positioning the hair dryer close to the hair and rapidly adjusting the airflow rate.

[0360] Above, for each part of the dehumidifier, the imaginary line passing through the center of the part is called the “center line,” but for convenience of explanation, it could also be called the “extension line.”

[0361] According to the dehumidifier of the present invention, the airflow discharged from the fan is concentrated, thereby increasing the airflow velocity and improving discharge performance. Therefore, the dehumidifier has significant industrial applicability.
