Description

Technical Field

[0001] This utility model relates to a dehumidifier. Background Technology

[0002] A dehumidifier is a household appliance that draws in air from a desired space, removes moisture from the air through heat exchange, and then releases the dehumidified air into the desired space, thereby reducing the humidity of the desired space.

[0003] The dehumidifier draws in air from the required space and passes it through a heat exchanger consisting of a condenser and an evaporator, thereby exchanging heat between the refrigerant flowing in the condenser and evaporator and the air flowing through it to remove moisture.

[0004] The evaporator absorbs heat from the surrounding air by evaporating liquid refrigerant, and the condenser releases heat by condensing gaseous refrigerant, thereby transferring heat to the surrounding air.

[0005] That is, the air flowing through the heat exchanger exchanges heat with the refrigerant while flowing through the evaporator, thereby reducing the humidity. The air with reduced humidity then flows through the condenser and exchanges heat with the refrigerant, thereby carrying out the drying process.

[0006] As it flows through the heat exchanger, the dried air is expelled into the desired space, thereby reducing the humidity in the air of the desired space.

[0007] As the dehumidified air is expelled through the exhaust section, it is necessary to improve the exhaust performance and prevent excessive noise. Utility Model Content

Figure 3 This is a front perspective view of a dehumidifier according to an embodiment of the present invention. Figure 4 This is a top perspective view of a dehumidifier according to an embodiment of the present invention.

[0081] Reference Figures 1 to 4 According to an embodiment of the present invention, the dehumidifier 10 may have a slender shape with a relatively thin thickness along the front-to-back direction.

[0082] The dehumidifier 10 may have a three-dimensional shape and may have a first directional length L1, a second directional length L2, and a third directional length L3. The directions are defined below.

[0083] The first direction is the direction in which the water tank 130, compressor 161, and electrical device 170 are arranged, as described later, and can correspond to the left-right direction (x-axis direction) of the dehumidifier. Furthermore, the first direction can be understood as the direction from the first side portion 103 to the second side portion 104, as described later.

[0084] The second direction is the direction in which the air flowing through the fan 230 is discharged through the exhaust section 140, which can correspond to the vertical direction (y-axis direction) of the dehumidifier.

[0085] The third direction refers to the arrangement of the suction unit 112, heat exchanger 180, and fan 230, which can correspond to the front-to-back direction (z-axis direction) of the dehumidifier.

[0086] For example, when defining the first direction length L1, the second direction length L2, and the third direction length L3 of the dehumidifier 10, the second direction length L2 can be greater than the first direction length L1, and the first direction length L1 can be greater than the third direction length L3.

[0087] The dehumidifier 10 may include a body 100, which forms an exterior and houses a plurality of components for discharging dehumidified air. The body 100 may include a first housing 110 and a second housing 120.

[0088] The outer surface of the body 100 can be defined by the first housing 110 and the second housing 120. Specifically, the body 100 may include a front portion 101, a back portion 102, a first side portion 103, a second side portion 104, a top portion 105, and a bottom portion 106.

[0089] The first housing 110 is disposed on the upper side of the second housing 120, and the first housing 110 and the second housing 120 can be joined together. A fastening mechanism 115 can be provided at the joint surface of the first housing 110 and the second housing 120. For example, the fastening mechanism 115 may include a bracket and a fastening member.

[0090] Inside the first housing 110, a fan assembly 200 for generating airflow and a heat exchanger 180 for heat exchange of air can be configured.

[0091] A compressor 161, a water tank 130, and an electrical device 170 may be configured inside the housing 120.

[0092] The first housing 110 and the second housing 120 are configured such that the left and right ends extend in an arc shape with a predetermined curvature, and the aesthetics can be improved by forming smooth surfaces. That is, the first side portion 103 and the second side portion 104 may include smooth, arc-shaped curved surfaces.

[0093] The curvature of the portion forming the top portion 105 in the first side portion 103 can be configured to correspond to the curvature of the ejection portion 140, which will be described later.

[0094] The dehumidifier 10 may include a water tank 130 for storing water condensed in the air. The water tank 130 may be detachably disposed at the lower part of the dehumidifier 10. For example, the water tank 130 may be detachably disposed in the second housing 120.

[0095] The water tank 130 can be separated to the side of 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 the internal components of the dehumidifier is reduced.

[0096] When the dehumidifier is in operation, outside air is drawn in from the rear portion 102 of the dehumidifier 10 and discharged through the top portion 105. The rear portion 102 has an intake portion 112 for air intake, and the top portion 105 may have an exhaust portion 140.

[0097] The inhalation portion 112 is formed on the back surface portion 102 of the first housing 110, and the exhalation portion 140 can be formed by opening a portion of the top surface portion 105 of the first housing 110.

[0098] The discharge section 140 can guide the air flowing through the fan 230 to be discharged upwards from the dehumidifier. The discharge section 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.

[0099] For example, the ejection portion 140 may include a circular ejection portion with the width as its diameter.

[0100] The side edge of the top surface 105 includes an arc-shaped curved portion, and a portion of the outer peripheral surface of the circular ejector portion can form a curvature corresponding to the side edge of the top surface 105.

[0101] The center of curvature of a portion of the outer peripheral surface of the circular ejector can be formed to be the same as the center of curvature of the side edge of the top surface 105. According to this configuration, a portion of the outer peripheral surface of the circular ejector can extend parallel to the side edge of the top surface 105.

[0102] The dispensing portion 140 may be formed at a position offset to one side relative to the center in the left-right direction of the top surface portion 105. For example, the dispensing portion 140 may be formed closer to the first side surface portion 103 in the first side surface portion 103 and the second side surface portion 104.

[0103] The discharge section 140 may be equipped with discharge blades 145 for adjusting the direction of the discharged airflow. The discharge blades 145 may be movable or rotatable.

[0104] The interior of the body 100 may be configured with a flow section and a drive section. The flow section includes components for generating airflow and performing heat exchange, and the drive section includes the main drive components and processing components required for the operation of the dehumidifier.

[0105] The flow section and the drive section can be configured vertically. For example, the flow section can be configured above the drive section, and an internal frame 150 can be configured between the flow section and the drive section to separate them.

[0106] The flow section may include a heat exchanger 180 disposed inside the intake section 112 and a fan assembly 200 disposed in front of the heat exchanger 180 and drawing in air flowing through the heat exchanger 180.

[0107] The heat exchanger 180 may include an evaporator 181 and a condenser 183. The evaporator 181 and the condenser 183 may be arranged side by side along the direction of airflow, i.e., in the front-to-back direction.

[0108] The heat exchanger 180 may also include a pipe section 185 disposed on the side of the evaporator 181 and the condenser 183 to guide the flow of refrigerant into and out of the evaporator 181 and the condenser 183.

[0109] The evaporator 181 can be disposed between the intake section 112 and the condenser 183, so that the air drawn in through the intake section 112 is first cooled by flowing through the evaporator 181 and then heated by flowing through the condenser 183.

[0110] If the air is cooled as it flows through the evaporator 181, the moisture in the air is condensed to form condensate, thereby dehumidifying the air. The condensate can be stored in a water tank 130.

[0111] The dehumidified air can be heated as it flows through the condenser 183 and then drawn into the fan assembly 200. The air flowing through the fan assembly 200 can be discharged through the exhaust portion 140 located at the upper end of the fan assembly 200.

[0112] The drive unit may include a water tank 130 for storing condensate generated in the evaporator 181. For example, the water tank 130 may be configured to protrude toward a second side portion 104 of the body 100. A user can pull the water tank 130 out from the side of the second side portion 104.

[0113] The drive section may further include a compressor 161, which compresses refrigerant to operate a refrigeration cycle. The refrigerant compressed in the compressor 161 flows into the condenser 183 through the conduit 185.

[0114] The 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 around the internal frame 150.

[0115] The drive section may also include an electrical device 170 having electrical components of a dehumidifier.

[0116] The water tank 130, the compressor 161, and the electrical device 170 can be arranged in a left-right direction, for example, they can be arranged from the second side portion 104 toward the first side portion 103.

[0117] The internal frame 150 may include a partition 151 that divides the internal space of the body 100 vertically to separate the flow portion and the drive portion.

[0118] The internal frame 150 may also include a plurality of partition walls 153, 155 extending from the partition plate 151 toward the drive portion and separating the receiving space of the components of the drive portion.

[0119] The plurality of partition walls 153, 155 may include a first partition wall 153, which defines the receiving space of the water bucket 130. The first partition wall 153 extends downward from the partition plate 151 and is supported by the bottom surface 106. The body 100, the first partition wall 153, and the partition plate 151 define the receiving space of the water bucket 130.

[0120] The plurality of partition walls 153, 155 may further include a second partition wall 155 for defining a receiving space for the compressor 161 and the electrical device 170. The second partition wall 155 may extend downward from the partition plate 151 and be supported by a bottom surface 106. The second partition wall 155 may be configured to be laterally spaced from the first partition wall 153.

[0121] The first partition wall 153, the second partition wall 155, and the partition plate 151 define the accommodating space of the water bucket 130. Additionally, the main body 100, the second partition wall 155, and the partition plate 151 define the accommodating space of the electrical device 170.

[0122] Reference Figure 4 When viewed from above, the exhaust section 140 can be tilted to one side from the center C1 of the top surface 105.

[0123] Specifically, when a center line lc is defined that extends from the left-right center C1 to the front-back direction, the center line lc can divide the top surface 105 into a first region where the ejection portion 140 is located and a second region on the opposite side.

[0124] That is, the dispensing portion 140 can be formed in a first region defined on both sides of a first region and a second region relative to the center of the top surface portion 105. The dispensing portion 140 can be located adjacent to the side edge of the top surface portion 105, and the two ends of the dispensing portion 140 can be located in the first region.

[0125] The centerline l2' passing through the center of the fan 230 in the vertical direction (refer to) Figure 14 It can pass through the second region.

[0126] The center of the discharge section 140 may be off-center relative to the center of the fan 230.

[0127] The centerline l1′ in the vertical direction passing through the center of the heat exchanger 180 or the center of the dehumidifier (refer to) Figure 14 It can be located on the centerline l3′ in the vertical direction passing through the center of the ejector section 140 (refer to...). Figure 14 Between the centerline l2' in the vertical direction passing through the center of the fan.

[0128] The fan housing 201 may include a cutout 215 forming the boundary between the intake side and the exhaust side of the fan 230, and a centerline l42 in the vertical direction passing through the center of the cutout 215 (see below). Figure 17b It can pass through the first region of the top surface 105.

[0129] The entire area of ​​the ejection portion 140 can be formed to be closer to the first side portion 103 than the second side portion 104.

[0130] The first curved portion 140a, closest to the first side portion 103, on the outer peripheral surface of the discharge portion 140 can be formed to have a curvature corresponding to the second curved portion 103a of the first side portion 103. The first curved portion and the second curved portion can have the same curvature center Cr (refer to...). Figure 13 ).

[0131] The dispensing portion 140 may have a circular shape. When a left-right center line lo is defined that passes through the center of the dispensing portion 140 and bisects the dispensing portion 140 in the front-back direction, the left-right center line lo can bisect the top portion 105 in the front-back direction.

[0132] That is, the left-right center line lo can bisect the ejection part 140 in the front-back direction and at the same time bisect the top part 105 in the front-back direction.

[0133] The discharge section 140 is movably provided with a plurality of discharge blades 145, which can be connected by blade connecting rods 144 extending in the left-right direction. The blade connecting rods 144 can be located on the center line lo in the left-right direction.

[0134] By moving the blade connecting rod 144 in the left and right direction, the plurality of ejector blades 145 rotate together, thereby selectively opening and closing the ejector section 140. For example, the plurality of ejector blades 145 can be operated manually.

[0135] Inside the main body 100, a fan shroud 201 can be configured to form the airflow path of the fan 230. The fan shroud 201 can be understood as a "vortex shroud" that expands the airflow path along the rotation direction of the fan 230.

[0136] The fan housing 201 may include a housing body 210 for housing the fan 230 and a throttling orifice 220 connected to the housing body 210 and drawing in air flowing through the heat exchanger 180.

[0137] The throttling orifice 220 may include a support plate 228 located at the upper end of the heat exchanger 180.

[0138] The fan housing 201 may include a joint portion 202 that defines the interface between the housing body 210 and the throttling orifice 220, and the housing body 210 and the throttling orifice 220 may be in surface contact through the joint portion 202.

[0139] The contact surfaces of the cover body 210 and the throttling orifice 220 can be located on the left-right centerline lo.

[0140] With this configuration, the heat exchanger 180 and the fan 230 form a stable center of gravity in a position that is approximately symmetrical about the front and back of the dehumidifier, and facilitates the uniform discharge of air flowing through the fan 230 through the entire area of ​​the discharge section 140.

[0142] Reference Figures 5 to 8 The dehumidifier 10 according to this utility model may include a first housing 110 forming an intake portion 112 and an exhaust portion 140. The intake portion 112 is formed on the back side of the first housing 110, and the exhaust portion 140 may be formed on the top surface of the first housing 110.

[0143] The air drawn in through the intake section 112 can flow upward after passing through the heat exchanger 180 and the fan 230, and then be discharged through the exhaust section 140.

[0144] A blade assembly 142 can be installed in the discharge portion 140. The blade assembly 142 may have a disc shape so as to fit tightly into the inner circumferential surface of the discharge portion 140.

[0145] The blade assembly 142 may include an annular support edge 143 and a discharge blade 145 movably disposed inside the support edge 143. A blade connecting rod 144 movable in the left-right direction may be provided at the center of the discharge blade 145 to guide the movement of the discharge blade 145.

[0146] A flow section may be provided inside the first housing 110. The flow section may include a heat exchanger 180 disposed inside the suction section 112. The heat exchanger 180 may include an evaporator 181, a condenser 183 on the outlet side of the evaporator 181, and a pipe section 185 on the side of the evaporator 181 and the condenser 183.

[0147] The flow section may also include a fan assembly 200 disposed on the outlet side of the heat exchanger 180 and forming a fan flow path.

[0148] The fan assembly 200 may include a housing body 210 that houses a fan 230 and has an open rear end. The housing body 210 may include a fan mounting portion 211 for mounting the fan 230. To allow the fan 230 to rotate, the fan 230 may be positioned slightly spaced from the fan mounting portion 211.

[0149] The surface forming the fan mounting portion 211 can form the "bottom surface" of the cover body 210.

[0150] The fan mounting portion 211 may be provided approximately at its central part to support the fan motor 237 (see reference). Figure 10 The motor support portion 212 may have an annular shape that protrudes rearward from the fan mounting portion 211 and surrounds the outer periphery of the fan motor 237.

[0151] The cover body 210 may also include a vortex portion 213 extending along the circumferential direction of the fan to surround the outer peripheral surface of the fan 230.

[0152] The vortex section 213 may include an inner peripheral surface that gradually moves away from the center of the fan 230 along the direction of fan rotation, thereby causing the fan flow path 205 (see reference) to... Figure 9 It expands (expands) along the rotation direction of the fan 230. For example, the vortex 213 may have a volute-shaped vortex.

[0153] The cover body 210 may further include an outlet guide 214, which is connected to the fan mounting portion 211 and forms a downstream flow path 205b of the fan 230 in the fan flow path 205 (see reference). Figure 16 Since the downstream flow path 205b is connected to the discharge section 140, it can be named the "discharge side flow path".

[0154] The discharge guide 214 can be connected to the discharge side portion of the vortex section 213. The discharge side portion of the vortex section 213 may include the portion of the fan flow path 205 that is maximized.

[0155] The discharge guide 214 can be configured to be recessed forward to increase the area of ​​the downstream flow path 205b. The area of ​​the downstream flow path 205b can be increased by increasing the size of the recess. By increasing the flow path area, a sufficient flow rate of air discharged to the discharge section 140 can be ensured.

[0156] The ejection guide 214 may be concave in an arc shape. The ejection guide 214 corresponds to the circular shape of the ejection portion 204 and may have a radius of curvature corresponding to the radius of curvature of the ejection portion 204.

[0157] The end of the ejection guide 214 may include a first ejection portion 216 connected to the ejection portion 140. The first ejection portion 216 may be formed at the end of the vortex portion 213.

[0158] The cover body 210 may further include a boundary portion 217 that defines the interface between the fan mounting portion 211 and the discharge guide portion 214. Based on the boundary portion 217, the distance between the fan 230 and the discharge guide portion 214 may be greater than the distance between the fan 230 and the fan mounting portion 211.

[0159] The cover body 210 may further include a cutout 215 that forms the boundary between the exhaust and re-intake of airflow. The cutout 215 may be configured to span the starting portion of the vortex portion 213 and the portion formed by the boundary portion 217, with reference to the rotation direction of the fan 230.

[0160] For example, the cut portion 215 may include a first end connected to the boundary portion 217 and a second end connected to the starting portion of the vortex portion 213.

[0161] The fan assembly 200 may further include a throttling orifice 220 covering a portion of the open end of the shroud body 210. The throttling orifice 220 may be attached to the front of the shroud body 210.

[0162] The orifice 220 may include an orifice body 221 that forms an intake port 223 for drawing in air flowing through the heat exchanger 180. The intake port 223 may be formed on one axial side of the fan 230 and may be generally circular in shape.

[0163] The throttling orifice 220 may be disposed at the upper end of the throttling orifice body 221, and may include a second discharge portion 226 that cooperates with the first discharge portion 216 of the cover body 210. If the first discharge portion 216 and the second discharge portion 226 are assembled, a discharge portion having a circular shape corresponding to the discharge portion 140 can be formed.

[0164] The blade assembly 142 can be installed on the portion where the first ejection portion 216 and the second ejection portion 226 are assembled. The blade assembly 142 can be installed on the upper end of the first ejection portion 216 and the second ejection portion 226.

[0165] The throttling orifice 220 can be located above the suction port 223, and a support plate 228 supporting the upper end of the heat exchanger 180 can be provided. The heat exchanger 180 can be configured in the space between the support plate 228 and the partition plate 151.

[0166] The support plate 228 can be positioned corresponding to a portion of the downstream flow path 205b through which the air flowing through the fan 230 is discharged toward the discharge section 140. Alternatively, the support plate 228 can be positioned corresponding to the cutout 215.

[0167] The throttling orifice 220 may also include a chamfer portion 227 that expands from the support plate 228 toward the second discharge portion 226 in a direction that increases the air discharge area.

[0168] The chamfered portion 227 can have an upwardly enlarged flow path cross-sectional area, causing the air discharged through the downstream flow path 205b to expand and be discharged towards the discharge portion 140. This configuration has the advantage of increasing the discharge area of ​​the discharged air.

[0169] The fan assembly 200 may further include a fan 230 disposed in the space defined by the housing body 210 and the throttle hole 220.

[0170] The fan 230 may include a centrifugal fan that draws in air axially and discharges it radially. For example, the centrifugal fan may include a multi-bladed fan.

[0171] The fan 230 may include a mainboard 231 attached to the motor shaft of the fan motor 237. For example, the mainboard 231 may be disc-shaped.

[0172] The fan 230 may be disposed at approximately the center of the motherboard 231 and may include a hub 232 that provides rotational force to the fan 230. The hub 232 may include a shaft engagement portion 232a for engagement with the motor shaft.

[0173] The hub 232 can protrude from the center of the main board 231 toward the intake port 223. The motor shaft can pass through the protruding portion of the hub 232 and be coupled to the fan motor 237.

[0174] The fan 230 may include an edge 233 spaced axially from the motherboard 231 and a plurality of blades 234 connecting the spaced portions of the motherboard 231 and the edge 233.

[0175] The edge 233 can be annular. The edge 233 can be parallel to the motherboard.

[0176] The plurality of blades 234 may be configured to have a length extending along the motor shaft in the front-to-back direction. The plurality of blades 124 may be configured to be arranged in a circumferential direction.

[0177] An internal frame 150 may be provided inside the body 100 to separate the flow section and the drive section vertically. The internal frame 150 may include a partition plate 151 that supports the heat exchanger 180 and the fan assembly 200.

[0178] The partition plate 151 may include a heat exchanger support portion 152a supporting the lower part of the heat exchanger 180 and a fan support portion 152b supporting the lower part of the fan assembly 200. The heat exchanger support portion 152a and the fan support portion 152b may be arranged in a front-back direction.

[0179] The heat exchanger support 152a may include a support bracket 152d that supports the bottom surface of the heat exchanger 180.

[0180] A drain port 152c for discharging condensate generated in the heat exchanger 180 can be formed in the heat exchanger support 152a (see reference). Figure 12 ).

[0181] The internal frame 150 may further include a first partition wall 153 extending downward from the partition plate 151 and a second partition wall 155 separated from the first partition wall 153 in a left-right direction.

[0182] A water tank accommodating space 157, where the water tank 130 is located, can be formed between the first partition wall 153 and the main body 100. The water tank accommodating space 157 can be formed to be adjacent to the second side surface 104.

[0183] An electrical accommodating space 158, where the electrical device 170 is located, can be formed between the second partition wall 155 and the main body 100. The electrical accommodating space 158 can be formed to be adjacent to the first side surface portion 103.

[0184] A compressor housing space 156, where the compressor 161 is located, can be formed between the first partition wall 153 and the second partition wall 155. The compressor housing space 156 can be formed between the water tank housing space 157 and the electrical housing space 158.

[0185] The interior of the second housing 120 can form a space 122 for accommodating the drive components, namely the water tank 130, the compressor 161, and the electrical device 170. As described above, the water tank 130, the compressor 161, and the electrical device 170 can be arranged in a left-right direction.

[0186] The portion of the second side surface 104 formed in the second housing 120 may form a housing opening 123 that opens to the side, so as to allow the water bucket 130 to be pulled out and inserted. The housing opening 123 may communicate with the water bucket receiving space 157.

[0187] The bottom surface of the second housing 120 may include a base 121 that supports the water tank 130, the compressor 161 and the electrical device 170.

[0188] The base 121 may include a first base portion 121a supporting the water tank 130, a second base portion 121b supporting the compressor 161, and a third base portion 121c supporting the electrical device 170 (see reference). Figure 9 For example, the first base portion 121a, the second base portion 121b, and the third base portion 121c can be configured as steps with different heights.

[0189] Figure 9 It is along Figure 1 A three-dimensional cross-sectional view taken along line 9-9. Figure 10 It is along Figure 1 A three-dimensional cross-sectional view taken along line 10-10. Figure 11 It is along Figure 1 A three-dimensional cross-sectional view taken along line 11-11. Figure 12 This is a side sectional view taken along the center of the dehumidifier according to an embodiment of the present invention.

[0190] Figure 9 It is a cross-sectional view taken along line 9-9 extending from the center of the ejector section 140 in the left-right direction. Figure 10 This is a three-dimensional cross-sectional view taken along a line extending 10-10 through the center of the dehumidifier. Additionally, Figure 11 It is a cross-sectional view taken along line 10-10 extending from the center of the ejector section 140 in the front-back direction.

[0191] Reference Figures 9 to 12 According to an embodiment of the present invention, the interior of the main body 100 may form a space (hereinafter referred to as the installation space) for the main components of the dehumidifier.

[0192] A water tank 130, a compressor 161, and an electrical device 170 can be installed in the lower part of the space. The compressor 161 is located between the water tank 130 and the electrical device 170, and the center line in the vertical direction passing through the center of the fan 230 can pass through the compressor housing space 156.

[0193] The height of the compressor 161 can be made smaller than the height of the water tank 130 and the height of the electrical device 170.

[0194] In the structure of the fan housing 201 including the vortex section 213, the central side portion of the lower end of the fan housing 201 is located at the lowest position, so the water tank 130, the compressor 161 and the compressor 161 in the electrical device 170 can be arranged on the lower side of the central portion of the fan housing 201.

[0195] A fan housing 201 for accommodating the fan 230 can be provided in the upper part of the setting space. The axis of the fan 230 can be oriented in the front-rear direction of the dehumidifier, and the air drawn in through the suction unit 112 can be drawn in along the axis of the fan 230 while moving forward.

[0196] The fan housing 201 may include a vortex section 213 whose outer diameter gradually increases along the rotation direction of the fan 230. A fan flow path 205 may be formed between the fan 230 and the vortex section 213, allowing air flowing through the fan 230 to flow toward the discharge section 140.

[0197] The fan 230 can be mounted on the cover body 210. The cover body 210 may include a fan mounting portion 211 for mounting the fan 230. The fan mounting portion 211 may form a portion of the front side of the cover body 210.

[0198] The main body 210 of the enclosure may also include a cutout 215 that forms the boundary between the exhaust and re-intake of the airflow of the fan 230. The cutout 215 may be formed at an angle relative to a centerline in the vertical direction passing through the center of the fan 230.

[0199] The cutout 215 defines the starting point of the fan flow path 205. The distance between the cutout 215 and the fan 230 can correspond to the minimum width in the fan flow path 205.

[0200] The cover body 210 may further include a discharge guide 214, which is connected to the fan mounting portion 211 and defines the discharge side flow path in the fan flow path 205. The discharge guide 214 may be formed to be recessed in the direction of increasing the width of the discharge side flow path, for example, forward.

[0201] The ejection guide 214 may include a curved portion that extends in an arc shape.

[0202] The ejection guide 214 may include a boundary portion 217 extending from the fan mounting portion 211 and forming an interface between the fan mounting portion 211 and the ejection guide 214.

[0203] The boundary portion 217 can extend linearly along the vertical direction of the fan housing 201.

[0204] The cutout portion 215 may include an end portion 215a connected to the boundary portion 217 (see reference). Figure 16 The end portion 215a can be understood as the end portion closest to the ejection guide portion 214 in the inclined shape of the cut portion 215.

[0205] The boundary portion 217 can extend downward from the end portion 215a to the fan housing 201.

[0206] The upper end of the ejection guide 214 may correspond to the upper end of the cut portion 215. The blade assembly 142 is disposed at the upper end of the ejection guide 214, and the ejection blade 145 of the blade assembly 142 can open or close the ejection portion 140 by operation.

[0207] Reference Figure 10 The vertical centerline passing through the center of the dehumidifier 10 can pass through the fan motor 237 and approximately through the center of the heat exchanger 180. Furthermore, the vertical centerline and the center of the fan 230 can be offset horizontally.

[0208] The fan housing 201 may include a housing body 210 for accommodating the fan 230 and a throttling orifice 220 attached to the rear of the housing body 210.

[0209] The throttling orifice 220 may include a support plate 228 supporting the upper end of the heat exchanger 180. The support plate 228 may be configured at a position lower than the upper end where the throttling orifice 220 and the cover body 210 are joined.

[0210] Reference Figure 11 The centerline in the front-back direction passing through the center of the discharge section 140 can pass through the heat exchanger 180.

[0211] The outermost end of the fan 230 and the center line in the front-back direction can be eccentric in the left-right direction, so that the center line in the front-back direction does not pass through the fan 230. The outermost end of the fan 230 can be understood as the end closest to the first side portion 103 of the dehumidifier 10.

[0212] Reference Figure 12 This explains the airflow.

[0213] When the fan motor 237 is driven and the fan 230 rotates, external air can be drawn into the dehumidifier through the intake section 112. The drawn-in air can then pass through the heat exchanger 180.

[0214] Specifically, the air first flows through the evaporator 181 in the heat exchanger 180 and is cooled. The condensate produced in this process can fall into the water tank 130 through the drain port 152c of the heat exchanger support 152a.

[0215] Air flowing through the evaporator 181 is heated as it flows through the condenser 183 located downstream of the evaporator 181. Air flowing through the condenser 183 can be drawn in along the axial direction of the fan 230 and discharged radially via the blades 234 of the fan 230.

[0216] The exhaust air flows through the fan flow path 205 between the vortex section 213 and the fan 230 while expanding in the direction of rotation of the fan 230. The air can flow through the discharge guide section 214 while flowing through the enlarged flow path, ensuring sufficient flow rate in the process.

[0217] The cutout 215 prevents air flowing through the discharge guide 214 from being re-inhaled and facilitates discharge into the discharge section 140.

[0218] On the other hand, the area of ​​the discharge side flow path can be increased by providing a chamfered portion 227 in the throttling orifice 220. The chamfered portion 227 is provided in a position opposite to the discharge guide portion 214 and can extend obliquely to increase the cross-sectional area of ​​the flow path upward.

[0219] With this configuration, the discharge flow rate can be ensured by increasing the area of ​​the discharge side flow path of the fan 230, and the discharge section 140 connected to the discharge side flow path can concentrate the discharge of air.

[0220] Figure 13 This is a top view of a dehumidifier showing the relative positions of the fan, heat exchanger, and discharge section according to an embodiment of the present invention. Figure 14 This is a schematic diagram showing the relative positions of the fan, heat exchanger, and discharge section according to an embodiment of the present invention. Figure 15a This is a diagram illustrating a prior art dehumidifier with a slit-shaped discharge section. Figure 15b This is a diagram showing the dehumidifier of this invention with a circular discharge section.

[0221] First, refer to Figure 13 When viewed from above the dehumidifier 10, the heat exchanger 180 and the fan 230 can be arranged in the front-to-back direction, and the discharge section 140 can be arranged to the side of the heat exchanger 180 and the fan 230.

[0222] A first center line l1 passing through the center of the heat exchanger 180 or the top surface 105 in a front-back direction, a second center line l2 passing through the center of the fan 230 in a front-back direction, and a third center line l3 passing through the center of the discharge section 140 in a front-back direction can be defined.

[0223] The first center line l1, the second center line l2, and the third center line l3 may be offset from each other. The second center line l2 may be separated from the first center line l1 by a first distance S1 in the direction toward the second side portion 104, and the third center line l3 may be separated from the first center line l1 by a second distance S2 in the direction toward the first side portion 103.

[0224] The first center line l1 may be located between the second center line l2 and the third center line l3.

[0225] The center of the discharge section 140 can be located closer to the first side portion 103 than the outermost end 230a of the fan 230, so that the air discharged from the fan 230 along the vortex section 213 can flow a short distance to the discharge section 140 and be discharged in a concentrated manner.

[0226] That is, the distance from the center of the discharge portion 140 to the first side portion 103 can be less than the distance from the outermost end portion 230a of the fan 230 to the first side portion 103.

[0227] The ejector portion 104 of the blade assembly 142 can be formed adjacent to the first side portion 103.

[0228] Specifically, the first curved portion 140a closest to the first side surface 103 on the outer peripheral surface of the dispensing portion 140 can be formed to have a curvature corresponding to the second curved portion 103a of the first side surface 103, and the first and second curved portions can have the same curvature center Cr. Furthermore, the curvature center Cr can form the center of the dispensing portion 140.

[0229] Next, refer to Figure 14 A first center line l1' passing through the center of the heat exchanger 180 in the vertical direction, a second center line l2' passing through the center of the fan 230 in the vertical direction, and a third center line l3' passing through the center of the discharge section 140 in the vertical direction can be defined.

[0230] The first center line l1', the second center line l2', and the third center line l3' can be offset from each other.

[0231] The second center line l2' can be separated from the first center line l1' by a first distance S1 in the direction toward the second side portion 104, and the third center line l3' can be separated from the first center line l1' by a second distance S2 in the direction toward the first side portion 103.

[0232] The first centerline l1′ can be located between the second centerline l2′ and the third centerline l3′.

[0233] The fan flow path 205 formed in the fan housing 201 may include an upstream flow path 205a and a downstream flow path 205b. The upstream flow path 205a may extend from the cutout 215 along the rotation direction of the fan 230.

[0234] The downstream side flow path 205b can define an outlet side flow path that is formed downstream of the upstream side flow path 205a and guides air to the outlet 140.

[0235] The downstream flow path 205b can be formed opposite the upstream flow path 205a with the second center line l2' as a reference. Through the configuration of the vortex section 213, the flow path width (or cross-sectional area) of the downstream flow path 205b can be greater than the flow path width (or cross-sectional area) of the upstream flow path 205a.

[0236] Reference Figure 15a When the discharge section 140' has a slit structure that is transversely elongated along the top surface of the dehumidifier, the distance between the discharge side flow path of the fan and the two ends of the discharge section 140' can be different from each other.

[0237] Since air tends to be discharged toward the center of the discharge section 140', dead zones Dz1 and Dz2, where the amount of air discharged is small or nonexistent, can be formed at both ends of the discharge section 140', which are located at a relatively far distance from the center of the discharge section 140'.

[0238] Therefore, there may be problems such as difficulty in effectively exhausting air and generating noise in dead zones.

[0239] Reference Figure 15b According to an embodiment of the present invention, the discharge portion 140 can be formed offset to one side relative to the center of the top surface 105 of the dehumidifier.

[0240] Since the discharge section 140 is located adjacent to the discharge side flow path of the fan, and the discharge section 140 is circular, the outer peripheral surface of the discharge section 140 is equidistant from the center of the discharge section, thus enabling concentrated air discharge. Furthermore, the airflow velocity can be increased.

[0241] According to this configuration, when attempting to dehumidify a specific space or item using a dehumidifier, dehumidification performance can be improved by centrally exhausting air.

[0242] For example, placing a dehumidifier next to a clothes drying rack with its exhaust fan facing the clothes will concentrate the air directed towards them, thus drying the clothes quickly.

[0243] Figure 16 This is a longitudinal sectional view taken along the center of the dehumidifier according to an embodiment of the present invention. Figure 17a This is a schematic diagram showing the internal structure of a prior art dehumidifier with a slit-shaped discharge section. Figure 17b This is a schematic diagram showing the internal structure of the dehumidifier of this invention, which has a circular discharge section.

[0244] Reference Figure 16 The upstream flow path 205a and the downstream flow path 205b of the fan flow path 205 can be formed on opposite sides of each other relative to the center of the fan 230.

[0245] The downstream flow path 205b extends upward and laterally from the fan 230, thereby connecting to the blade assembly 142. The uppermost end of the downstream flow path 205b defines a first discharge portion 216 of the shroud body 210 and a second discharge portion 226 of the throttling orifice 220, to which the blade assembly 142 can be attached.

[0246] The flow path width w1 of the discharge portion defined by the first discharge portion 216 and the second discharge portion 226 can form the maximum width of the downstream flow path 205b.

[0247] The dispensing section 140 may be located directly above the dispensing portion. Furthermore, the flow path width w2 of the dispensing section 140 may be substantially the same as the flow path width w1 of the dispensing portions 216 and 226.

[0248] The center of the ejection portion 140 can be concentric with the center of the ejection portions 216 and 226.

[0249] As an example, since the discharge portion 140 can be configured as a circular discharge portion, and the discharge portion has a circular shape, the widths w1 and w2 can be defined as the diameters of the circle. According to this configuration, the air flowing through the discharge portion can be concentrated and discharged through the discharge portion 140.

[0250] A cutout 215 may be provided in 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 drawn back into the upstream flow path 205a.

[0251] The cutout portion 215 may include a first end portion 215a connected to the boundary portion 217 and a second end portion 215b defining the starting point of the upstream flow path 205a. The cutout portion 215 may extend obliquely from the first end portion 215a toward the second end portion 215b, relative to a reference line in the vertical direction.

[0252] Reference Figure 17a Because the exhaust section 140' is elongated in the left-right direction, the airflow from the fan can be directed upwards towards the exhaust section. During this process, dead zones Dz1 and Dz2 with little or no airflow can be formed at both ends of the exhaust section.

[0253] In order to expel air into the elongated, slender section formed along the left and right directions, the fan's cutout 215a extends from the center of the fan to the left ( Figure 17a (Based on) eccentric configuration.

[0254] That is, the left end of the discharge section is located at the position furthest from the discharge side flow path of the fan. In order to discharge air to the left end as much as possible, the cut-out portion 215a is located in the direction adjacent to the left end.

[0255] Specifically, the vertical centerline l21 passing through the center of the fan 230 can be located between the vertical centerline l41 passing through the center of the cutout 215' and the vertical centerline l31 passing through the center of the discharge portion 140.

[0256] On the other hand, the width of the discharge portion 140' can be made larger than the width of the discharge portion 116' of the fan housing that houses the fan 230. Therefore, the air discharged through the discharge portion 116' flows to the discharge portion 140' with an expanded flow path width, which may result in a decrease in flow rate.

[0257] Conversely, refer to Figure 17b According to an embodiment of the present invention, the cutout portion 215 can be eccentrically configured from the center of the fan toward the discharge portion 140.

[0258] Since the entire area of ​​the discharge section 140 is configured adjacent to the discharge-side flow path of the fan, it is not necessary to... Figure 17a That way, the cut 215 is positioned off-center to the left.

[0259] That is, since the cutout 215 is eccentrically positioned to the right of the fan center and closer to the discharge side flow path, it can more effectively prevent the discharged airflow from being re-inhaled into the fan side.

[0260] Specifically, the vertical center line l42 passing through the center of the cutout 215 can 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 section 140.

[0261] As described above, the width of the discharge portion 140 can be substantially the same as the width of the discharge portions 116 and 126 of the fan housing. Therefore, since the air discharged through the discharge portions 116 and 126 flows to the discharge portion 140 while maintaining the width of the flow path, the flow velocity can be maintained.

[0262] Therefore, it can improve the dehumidification performance of the object being dried. This can be said to be similar to the principle of quickly drying hair by bringing a hair dryer close to the hair and rapidly adjusting the airflow rate.

[0263] For the various components of the dehumidifier mentioned above, the imaginary line passing through the center of the component is called the "center line," but for ease of explanation, it can also be called the "extension line."

[0264] The following describes another embodiment of the present invention. This embodiment differs from the previous embodiment in the configuration of the water bucket and the dispensing section; therefore, the description will focus on the differences. For parts identical to the previous embodiment, the description and reference numerals from the previous embodiment will be used.

[0265] Figure 18 This is a rear perspective view showing the configuration of a dehumidifier according to another embodiment of the present invention. Figure 19 This is a longitudinal sectional view taken along the center of a dehumidifier according to another embodiment of the present invention.

[0266] Reference Figure 18 and Figure 19 According to another embodiment of the present invention, the dehumidifier 10a can be configured such that the exhaust section 140 for expelling air and the water tank 130 for storing condensate are aligned in a row in the vertical direction.

[0267] For example, the discharge portion 140 may be formed in the first side portion 103 and the second side portion 104 at a position close to the first side portion 103. This is the same as described in the previous embodiments.

[0268] Unlike previous embodiments, the bucket 130 can be configured to be exposed to the outside through the first side portion 103 of the first side portion 103 and the second side portion 104.

[0269] That is, the center line in the vertical direction passing through the center of the discharge section 140 can be configured to pass through the water bucket 130.

[0270] With this configuration, when the dehumidifier is placed in a designated space, the first side portion 103 can be configured to be exposed to the outside, at which time the user can easily access the first side portion 103 to connect or disconnect the water tank 130.

[0271] Furthermore, since the object to be dried can be positioned adjacent to the discharge section 140, the air discharged from the discharge section 140 can be concentrated and supplied to the object to be dried. Therefore, the drying performance of the object to be dried can be improved.

[0272] Industrial applicability

[0273] This utility model relates to a dehumidifier that concentrates the airflow emitted from a fan, thereby increasing the airflow velocity and improving the emission performance. Therefore, it has significant industrial applicability.
