Description

Technical Field

[0001] This utility model relates to dehumidifiers, and more specifically, to a dehumidifier having a heat dissipation structure for dissipating heat from an electrical assembly, the electrical assembly being provided for controlling the operation of the dehumidifier. Background Technology

[0002] Generally, a dehumidifier is a device or equipment that removes moisture from the air in an indoor space.

[0003] Such a dehumidifier is configured such that after drawing in air from a space where moisture needs to be removed, the air passes through a heat exchanger, where the air exchanges heat with the heat exchanger to remove the moisture from the air.

[0004] The heat exchanger includes a condenser for condensing the refrigerant and an evaporator for evaporating the refrigerant. That is, air exchanges heat with the refrigerant and loses moisture as it passes through the evaporator, and absorbs heat released from the refrigerant as it passes through the condenser, thus supplying the room in a dry state and reducing the humidity of the indoor space.

[0005] In addition, the dehumidifier has a water tank and collects and stores the moisture separated from the air during the process of passing through the evaporator, and then discharges it when necessary.

[0006] In relation to such existing dehumidifiers, various authorized patents are provided, including No. 10-2506410, No. 10-2025-0006644, No. 10-2025-0006645, No. 10-2025-0006646, and No. 10-2025-0006647.

[0007] On the other hand, the dehumidifier has an electrical assembly for controlling the operation of various devices, which generates a large amount of heat during the operation of the dehumidifier. Thus, the heat generated in the electrical assembly can affect the performance of surrounding components and, moreover, affect the various circuits constituting the electrical assembly.

[0008] Therefore, heat dissipation of the electrical assembly is necessary.

[0009] In the prior art, in addition to providing heat sinks on various circuit components or circuit boards that constitute the electrical assembly, an additional fan (box fan) is used to guide air and force it through the heat sink to dissipate heat from the electrical assembly.

[0010] However, when using the box-type fan structure, the overall size of the electrical assembly increases due to the additional space required for the box-type fan and the structure for airflow, which in turn increases the overall size of the dehumidifier.

[0011] In addition, if the compressor is installed around the perimeter of the space where the electrical assembly part is located, the box fan will cause the hot air generated by the compressor to flow towards the electrical assembly part, resulting in an insignificant cooling effect.

[0017] Problems to be solved by utility models

[0018] This utility model is proposed to solve the various problems of the prior art mentioned above. The purpose of this utility model is to provide a new type of dehumidifier that can smoothly dissipate heat from electrical assembly parts.

[0019] In addition, the purpose of this invention is to provide a new type of dehumidifier that can improve heat dissipation performance while minimizing the size of the electrical assembly parts.

[0020] In addition, the purpose of this invention is to provide a new type of dehumidifier that can utilize natural convection to dissipate heat from electrical assembly parts, thereby eliminating the need for an additional cooling fan.

[0021] In addition, the purpose of this utility model is to provide a new type of dehumidifier so that the air flowing into the space where the electrical assembly part is provided can be fully discharged after passing through the electrical assembly part, thereby improving the heat dissipation performance of the electrical assembly part.

[0022] Technical solutions to the problem

[0023] To achieve the above objectives, the dehumidifier according to the present invention can be configured such that indoor air drawn in by the air suction force generated by the operation of the fan assembly dissipates heat from the electrical assembly part as it passes through the electrical assembly part.

[0024] According to the present invention, in order to dissipate heat from the electrical assembly part, a structure can be provided for discharging air drawn in from outside the housing to the electrical assembly part.

[0025] According to the dehumidifier of this invention, the structure for dissipating heat from the electrical assembly part may include a heat dissipation guide. This allows air from outside the housing to be supplied to the electrical assembly part via the heat dissipation guide.

[0026] According to the dehumidifier of this utility model, a heat dissipation guide for dissipating heat from electrical assembly parts can be formed in the base frame.

[0027] According to the dehumidifier of this utility model, a heat dissipation guide can be formed in the basic frame to guide the air outside the housing to be discharged to the electrical assembly part.

[0028] According to the dehumidifier of this utility model, the heat dissipation guide part can be formed with an opening of a preset size or formed as a tube with an opening of a preset size.

[0029] According to the present invention, a partition frame for dividing the space within the housing into a plurality of partitions can be disposed within the housing.

[0030] According to the dehumidifier of this utility model, the partition frame can be formed to divide the interior of the housing into an upper space and a lower space.

[0031] According to the dehumidifier of this utility model, a first vertical partition wall can be formed in the partition frame for dividing the lower space within the housing to provide a first space and a second space.

[0032] According to the dehumidifier of this utility model, a second vertical partition wall can be formed in the partition frame for dividing the lower space within the housing to provide a second space and a third space.

[0033] According to the dehumidifier of this utility model, a first vertical partition wall and a second vertical partition wall can be formed in the partition frame for dividing the lower space within the housing to provide a first space, a second space and a third space.

[0034] According to the dehumidifier of this invention, the first space can be formed as a space between either side of the partition frame and the housing. An electrical assembly unit can be disposed within the first space.

[0035] According to the dehumidifier of this invention, the second space can be formed as a space between the partition frame and the other side of the casing. A water tank can be installed in the second space.

[0036] According to the dehumidifier of this invention, a third space may be provided between the first space and the second space. A compressor may be provided in the third space.

[0037] According to the dehumidifier of this utility model, an electrical assembly part can be installed in the first space, a water tank can be installed in the second space, and a compressor can be installed in the third space.

[0038] According to the dehumidifier of this invention, the heat dissipation guide can be configured to allow air to flow into the first space.

[0039] According to the dehumidifier of this invention, the heat dissipation guide can be formed as a tube protruding upward from the base frame and having an open interior. Therefore, even if condensate accumulates on the top of the base frame, leakage of condensate to the indoor floor through the heat dissipation guide can be prevented.

[0040] According to the dehumidifier of this invention, the heat dissipation guide portion can be formed to open onto a portion of the bottom surface of the electrical assembly portion. This allows air flowing into the exterior of the housing through the heat dissipation guide portion to be directly supplied to the electrical assembly portion.

[0041] According to the dehumidifier of this invention, the heat dissipation guiding part can be formed as an opening with elongated holes. Thus, the heat dissipation guiding part can expel air from outside the housing to as many locations as possible along the length of the bottom surface of the electrical assembly part.

[0042] According to the dehumidifier of this invention, a first opening can be formed on the bottom surface of the electrical assembly section. Thus, a portion of the air flowing into the housing through the heat dissipation guide section can be supplied to the electrical assembly section through the first opening.

[0043] According to the dehumidifier of this invention, the first opening and the opening of the heat dissipation guide can be staggered vertically. Therefore, a portion of the air flowing into the housing through the heat dissipation guide can pass through the electrical assembly section via the first opening.

[0044] According to the dehumidifier of this invention, a second opening can be formed on the top surface of the electrical assembly section. Thus, air passing through the electrical assembly section can flow through the second opening to the air inlet of the fan assembly.

[0045] According to the dehumidifier of this utility model, in order to dissipate heat from the circuit components by utilizing the air flowing along the outer surface of the electrical assembly part, the heat sink connected to the circuit components can be configured to expose to the outer surface of the electrical assembly part.

[0046] According to the dehumidifier of this utility model, the heat sink can be formed by a plurality of thin plates spaced apart from each other, and each thin plate can be formed to have different lengths along the inclination or curvature formed with the inner surface of the adjacent shell.

[0047] According to the dehumidifier of this invention, through holes can be formed in the partition frame to allow air to pass through. Thus, air used for heat dissipation from the electrical assembly parts can flow through these through holes into the upper space inside the housing.

[0048] According to the dehumidifier of this invention, the through hole can be vertically offset from the second opening on the top surface of the electrical assembly part. This prevents condensate falling from the through hole from flowing into the electrical assembly part through the second opening.

[0049] According to the dehumidifier of this invention, a guide member for guiding air that has passed through the electrical assembly part can be formed in the partition frame.

[0050] According to the dehumidifier of this invention, the openings of the guide member and the heat dissipation guide section can be staggered vertically. Therefore, air passing through the heat dissipation guide section can simultaneously dissipate heat from the electrical assembly section before flowing towards the guide member.

[0051] According to the dehumidifier of this utility model, in order to guide the air passing through the electrical assembly section to flow towards the guide member, the partition frame can be formed to be inclined upwards towards the periphery.

[0052] According to the dehumidifier of this utility model, in order to guide the air passing through the electrical assembly section to flow toward the guide member, the partition frame can be formed to be inclined upwards the closer to the part where the guide member is formed.

[0053] According to the dehumidifier of this utility model, the guide can be formed to connect the upper and lower spaces to each other at any periphery of the partition frame so that air can pass through.

[0054] According to the dehumidifier of this utility model, in order to prevent condensate on the top surface of the partition frame from falling downward through the guide, the upper end of the guide can be formed to protrude upward from the top surface of the partition frame.

[0055] According to the dehumidifier of this utility model, the through hole is offset from the second opening in the vertical direction.

[0056] According to the dehumidifier of this utility model, an exposure hole is formed on the outer surface of the electrical assembly part, and a heat sink for dissipating heat from the circuit components inside the electrical assembly part is arranged to be exposed from the exposure hole.

[0057] According to the present invention, the dehumidifier is formed by a plurality of thin plates spaced apart from each other, each of the thin plates being formed with different lengths along the inclination or curvature of the inner surface of the adjacent shell.

[0058] According to the present invention, a guide is formed in the partition frame for air that has passed through the electrical assembly part.

[0059] According to the dehumidifier of this utility model, the openings of the guide member and the heat dissipation guide part are staggered in the vertical direction.

[0060] According to the dehumidifier of this utility model, the partition frame is formed to tilt upwards towards the periphery, and the guide is formed to connect the upper and lower spaces to each other at any periphery of the partition frame.

[0061] According to the dehumidifier of this utility model, the upper end of the guide is formed to protrude upward from the top surface of the partition frame.

[0062] According to the dehumidifier of this utility model, the partition frame is formed such that it tilts upwards towards the portion where the guide is formed.

[0063] Utility Model Effect

[0064] As described above, in the dehumidifier of this invention, since a heat dissipation guide portion is formed in the basic frame, the electrical assembly portion can be cooled even without providing an additional cooling fan for heat dissipation.

[0065] In addition, since the dehumidifier of this invention does not provide an additional cooling fan, the volume of the electrical assembly parts can be minimized.

[0066] In addition, the dehumidifier of this invention can improve the heat dissipation performance of the electrical assembly by maximally separating the opening for air to flow into the first space where the electrical assembly is located and the opening for air to exhaust, and by placing the electrical assembly between the two openings.

[0067] In addition, in the dehumidifier of this invention, since the heat sink of the electrical assembly part can be formed to protrude to the outside of the housing, air can flow along the surface of the housing and pass through the heat sink, thereby improving the heat dissipation performance of the circuit components.

[0068] In addition, the dehumidifier of this invention has an additional opening formed in the electrical assembly section for allowing air to flow in or out. Therefore, it can use the air suction generated by the fan assembly to force the hot air in the electrical assembly section to be discharged to the outside of the housing and to force it to flow into the housing of the electrical assembly section to dissipate heat from the circuit components.

[0111] The following is for reference Figures 1 to 19 The preferred embodiment of the dehumidifier of this utility model will be described below.

[0112] Figures 1 to 3 These are perspective views and exploded perspective views of a dehumidifier according to an embodiment of this utility model. Additionally, Figure 4 This is a top view of the dehumidifier according to an embodiment of the present invention. Figure 5 and Figure 6 These are side views and sectional views observed from different directions.

[0113] As shown in the figure, the dehumidifier of this utility model embodiment includes a housing 100, a dehumidification part 200, a fan assembly 300, and an electrical assembly part 600. In particular, the electrical assembly part 600 can dissipate heat using a heat dissipation guide part 700.

[0114] The following is a detailed description of the various components of the dehumidifier according to such an embodiment of the present invention.

[0115] First, the dehumidifier of this utility model embodiment includes a housing 100.

[0116] The housing 100 can be defined as the portion that forms the peripheral wall of the dehumidifier's appearance.

[0117] The housing 100 can provide space for various components or devices to be installed inside, and the housing 100 can be configured to be open at the top and bottom.

[0118] The housing 100 may be formed by combining a plurality of parts together. For example, the housing 100 may be divided into a first peripheral housing 110 and a second peripheral housing 120 and provided thereon.

[0119] The first peripheral housing 110 forms the front of the dehumidifier, a portion of one sidewall, and a portion of the other sidewall; the second peripheral housing 120 forms the back of the dehumidifier, another portion of one sidewall, and another portion of the other sidewall. For ease of explanation, in... Figure 1 and Figure 2 In this state, the side facing which the water bucket 400 is located is defined as the right side, and the side facing the opposite direction of the water bucket 400 is defined as the left side. Figure 4 Based on this, the surface where the first peripheral housing 110 is provided can be defined as the front side, and the surface where the second peripheral housing 120 is provided can be defined as the back side. Although not shown, the housing 100 may also be additionally provided with an additional peripheral housing forming a sidewall.

[0120] An intake port 121 may be formed in the second peripheral housing 120. For example, an intake port 121 for drawing in air from outside the housing (e.g., indoor air) may be formed on the upper part of the second peripheral housing 120.

[0121] The lower right side of the housing 100 may be open. For example, the lower right side wall of the first peripheral housing and the lower right side wall of the second peripheral housing may be open. A water tank 400 may be detachably disposed within such an open portion. The water tank 400 may store moisture separated from the air.

[0122] Then, the dehumidifier of this utility model embodiment includes a basic frame 130.

[0123] The basic frame 130 can be defined as the part that forms the bottom of the dehumidifier's appearance.

[0124] The basic frame 130 is formed to seal the open bottom surface of the housing 100.

[0125] like Figure 5 and Figure 6As shown, a plurality of rolling members 131 for moving the dehumidifier can be provided on the bottom surface of the base frame 130.

[0126] The rolling member 131 can be provided as a caster.

[0127] Then, the dehumidifier of this embodiment includes an upper cover 140.

[0128] The upper cover 140 can be defined as the portion that forms the top surface of the dehumidifier's appearance.

[0129] The upper cover 140 is formed to cover the open top surface of the housing 100.

[0130] An outlet 141 may be formed on the upper cover 140. The outlet 141 may be formed on either side of the upper cover 140. For example, when viewed from above, the outlet 141 may be formed on the right side of the upper cover 140.

[0131] The discharge port 141 can be selectively opened and closed by the opening and closing door 142. The opening and closing door 142 can be opened and closed manually or automatically.

[0132] Although not shown in the figure, the first peripheral housing 110 and the second peripheral housing 120 can be integrally formed with each other, or any peripheral housing 110, 120 and the base frame 130 or any peripheral housing 110, 120 and the upper cover 140 can also be integrally formed with each other.

[0133] Then, the dehumidifier of this embodiment includes a partition frame 500.

[0134] The partition frame 500 can be defined as the internal body of the dehumidifier. That is, the space inside the housing 100 can be divided into a plurality of spaces by the partition frame 500.

[0135] The partition frame 500 can divide the space within the housing 100 vertically. Therefore, the partition frame 500 can be configured to laterally block the space between the upper and lower spaces within the housing 100. Thus, the space within the housing 100 can be divided into an upper space and a lower space by the partition frame 500.

[0136] Figures 7 to 10 The relationship between the partition frame 500 and the base frame 130 is shown.

[0137] As shown in the figure, a first vertical partition wall 510 and a second vertical partition wall 520 may be formed in the partition frame 500. The first vertical partition wall 510 and the second vertical partition wall 520 are provided to separate the first space 101, the second space 102 and the third space 103 in the lower space within the housing 100.

[0138] The first vertical partition wall 510 may be formed to protrude downward from either side of the bottom surface of the partition frame 500 to divide the lower space within the housing 100 into a first space 101 and a second space 102.

[0139] The second vertical partition wall 520 may protrude downward from the other side of the bottom surface of the partition frame 500 to divide the lower space within the housing 100 into a second space 102 and a third space 103.

[0140] by Figure 5 Based on this, the first space 101 can be defined as the space between either side of the partition frame 500 and the housing 100 (e.g., the left side of the periphery), and an electrical assembly 600 can be provided in such a first space 101.

[0141] The second space 102 can be defined as the space between the partition frame 500 and the other side circumferential surface (e.g., the right side circumferential surface) within the housing 100, in which a bucket 400 can be provided.

[0142] The third space 103 can be defined as the space between the first space 101 and the second space 102, and a compressor 230 can be installed in such a third space 103.

[0143] The dehumidifier 200 and fan assembly 300, described later, can be provided on the top surface of the partition frame 500. Therefore, the partition frame 500 also functions as a condensate collection section for catching condensate water falling from the dehumidifier 200.

[0144] The top surface of the partition frame 500 may be formed with a drain hole 501 for allowing the condensate to fall into the water tank 400 in the second space 102 (see reference). Figure 14 Meanwhile, the top surface of the partition frame 500 can be formed obliquely toward the drain hole 501 (see reference). Figure 10 Therefore, the condensate that flows onto the top surface of the partition frame 500 is directed to the drain hole 501 and can then fall into the bucket through the drain hole 501.

[0145] The bottom surface of the partition frame 500 can be formed to slope upwards towards the periphery. Specifically, the portion of the bottom surface of the partition frame 500 that forms the top surface of the first space 101 (the portion "C" in the drawing) can be formed to slope upwards towards the periphery. Preferably, the bottom surface of the partition frame 500 can be formed to slope upwards towards the periphery with respect to the drain hole 501. Thus, air rising from the first space 101 can flow obliquely along the bottom surface of the partition frame 500 towards the periphery.

[0146] On the other hand, a guide 530 can be formed at any location in the first space 101 within the periphery of the partition frame 500. This guide 530 guides air rising from the first space 101 through and directs it towards the upper space (the upper space within the housing) of the partition frame 500. That is, the guide 530 is configured to guide airflow from the uppermost portion of the bottom surface of the partition frame 500. Preferably, the partition frame 500 can be configured to slope upwards towards the portion where the guide 530 is formed. With this structure, air rising from the first space 101 can flow along the bottom surface of the partition frame 500 to the guide 530, and then, guided by the guide 530, flow towards the upper space within the housing 100.

[0147] like Figure 13 As shown, the guide 530 can be formed at an angle in the top surface of the first space 101. Thus, air rising from the bottom of the first space 101 can flow to the guide 530 along the inclined bottom surface of the partition frame 500 and then flow into the upper space inside the housing 100.

[0148] Although not illustrated, the guide 530 can be formed as an opening. However, if the guide 530 is simply formed as an opening, condensate that falls onto the top surface of the partition frame 500 may fall through the opening. Therefore, the guide 530 is formed such that its upper end protrudes further from the top surface of the partition frame 500, preventing condensate present on the top surface of the partition frame 500 from falling downwards through the guide 530.

[0149] Then, the dehumidifier of this utility model embodiment includes a dehumidification section 200.

[0150] The dehumidification unit 200 can be defined as a device, apparatus, or structure for separating moisture from the air.

[0151] For example, the dehumidification unit 200 can be configured to separate moisture contained in the air by utilizing heat exchange with the air through temperature difference. For this purpose, the dehumidification unit 200 may include heat exchangers 210 and 220.

[0152] The heat exchangers 210 and 220 can be located in the rear space of the upper space within the housing 100 (the space adjacent to the second peripheral housing).

[0153] The heat exchangers 210 and 220 may include an evaporator 210 for separating moisture from the air by utilizing the temperature difference with the air.

[0154] The air passing through the evaporator 210 exchanges heat with the low-temperature refrigerant in the evaporator 210 and is thus kept at a low temperature. If this low-temperature air is directly supplied to the room, it may cause dissatisfaction among users. Therefore, the heat exchangers 210 and 220 may include a condenser 220 for raising the temperature of the air.

[0155] The condenser 220 can be located on the air outlet side of the evaporator 210. Specifically, the evaporator 210 and condenser 220 are arranged to overlap along the airflow direction, providing a location within the housing 100 where the intake 121 of the second peripheral housing 120 is formed. For example, the evaporator 210 and condenser 220 can be located in the upper right-side space within the housing 100. The evaporator 210 can be positioned closer to the intake 121 than the condenser 220. With this configuration of the evaporator 210 and condenser 220, air flowing in from the intake 121 can be dehydrated and then resupplyed to the room at a higher temperature.

[0156] That is, the air drawn in through inlet 121 undergoes heat exchange while passing through the low-temperature evaporator 210, and moisture is separated by heat exchange with such a low temperature. The air passing through the evaporator 210 undergoes heat exchange while passing through the high-temperature condenser 220, and is heated to a suitable temperature by heat exchange with such a high temperature before being discharged into the room. Therefore, high-temperature dry air can be provided to the room.

[0157] During the process of passing through the evaporator 210, the moisture separated from the air flows down the surface of the evaporator 210, collects in the partition frame 500 located below the corresponding evaporator 210, and is then supplied to the water tank 400 below it through the drain hole.

[0158] On the other hand, the dehumidification unit 200 also includes a compressor 230 and an expander 240, and together with the heat exchangers 210 and 220, forms a refrigeration cycle.

[0159] The compressor 230 can be disposed in a second space in the lower space within the housing 100. By positioning the compressor 230, which is relatively heavier than other components, in the lower central part, it is possible to prevent the housing 100 from tipping over.

[0160] Then, the dehumidifier of this embodiment includes a fan assembly 300.

[0161] The fan assembly 300 can be defined as an assembly having a blower fan 310 for generating airflow.

[0162] Such a fan assembly 300 can be installed in the upper space inside the housing 100.

[0163] Specifically, such as Figure 2 and Figure 6 As shown, the fan assembly 300 can be located on the air outlet side of the heat exchangers (especially the condensers) 210 and 220. This allows air passing through the intake 121 and sequentially through the evaporator 210 and condenser 220 to flow into the fan assembly 300.

[0164] like Figure 2 and Figure 5 As shown, the fan assembly 300 includes an air supply fan 310 and a fan housing 320.

[0165] The fan housing 320 can be formed with an arc around the rotation center of the air supply fan 310, and an exhaust pipe 323 extending upward and guiding the airflow is formed at any periphery. The end of the exhaust pipe 323 is open and is set as an air outlet.

[0166] like Figure 6 As shown, the air outlet of the discharge duct 323 can be formed to coincide with the discharge outlet 141 of the upper cover 140 constituting the housing 100. That is, the discharge duct 323 extends upward from the upper part of the peripheral wall of the fan shroud 320 and coincides with the discharge outlet 141. Thus, the air flowing along the discharge duct 323 is discharged into the room after passing through the air outlet and the discharge outlet 141 of the upper cover 140 in sequence.

[0167] like Figure 4 As shown, a fan motor 324 is provided on the outer surface of the fan housing 320, and a blower fan 310 is provided inside the fan housing 320. The blower fan 310 is shaft-connected to the fan motor 324. The fan motor 324 can be located on the outer surface of the fan housing 320.

[0168] One side of the blower fan 310 (the side facing the heat exchanger) is open, and the blower fan 310 can be formed as a centrifugal fan (e.g., a Sirocco fan) with a plurality of blades formed along its periphery. Thus, by rotating the blower fan 310, air is drawn in from the air inlet of the fan housing 320. After flowing into the blower fan 310, the air is discharged in a radial direction, then flows along the peripheral wall of the fan housing 320 and is discharged to the outlet 141 through the discharge pipe 323.

[0169] Then, the dehumidifier of this embodiment includes an electrical assembly part 600.

[0170] The electrical assembly section 600 is a part or device composed of multiple circuit components used for the operation control of various devices.

[0171] Such an electrical assembly 600 can be located in the lower space within the housing 100. Specifically, the electrical assembly 600 can be located in a first space 101 within the housing 100. The electrical assembly 600 can be fixed to the wall surface of the first vertical partition wall 510 in the first space 101.

[0172] like Figure 3 and Figure 15 As shown, the electrical assembly part 600 may consist of a main PCB 610 having a plurality of circuit components 601 and a housing 620 that protects the main PCB 610 from the influence of the external environment.

[0173] To prevent the risk of fire caused by the heating or ignition of the circuit component 601, the housing 620 may be formed of metal or flame-retardant material.

[0174] The enclosure 620 may be configured to include two separable covers 621 and 622. Specifically, the enclosure 620 may include a first cover 621 forming the back side (the wall adjacent to the first vertical partition wall) and a second cover 622 forming the front side (the wall adjacent to the housing). Thus, the main PCB 610 housed inside the enclosure 620 can be maintained or repaired as needed by separating the two covers 621 and 622.

[0175] Then, the dehumidifier of this embodiment includes a heat dissipation guide 700.

[0176] The heat dissipation guide 700 can be defined as a part or component that guides airflow to dissipate heat from the electrical assembly part 600.

[0177] The heat dissipation guide 700 can be configured to dissipate heat from the electrical assembly 600 by utilizing the airflow generated within the housing 100 caused by the operation of the fan assembly 300, rather than forcing airflow. That is, the heat dissipation guide 700 allows indoor air drawn in by the suction force caused by the operation of the fan assembly 300 to pass through the electrical assembly 600, thereby enabling natural heat dissipation from the electrical assembly 600.

[0178] The heat dissipation guide 700 can be configured to allow indoor air to flow into the first space 101 where the electrical assembly part 600 is located. Therefore, the heat dissipation guide 700 can be formed at any of the locations forming the first space 101 (partition frame, first vertical partition wall, peripheral housing, and base frame).

[0179] This embodiment of the utility model shows that the heat dissipation guide 700 is formed in the base frame 130 at a location in the first space 101. That is, considering that the air suction force into the first space 101 is formed by the guide 530 of the partition frame 500 forming the top surface of the first space 101, indoor air flows in from the bottom surface of the first space 101, thereby enabling the air to pass through the first space 101 as fully as possible.

[0180] In particular, such as Figure 5 As shown, the heat dissipation guide 700 can be disposed in the base frame 130 at a position opposite the bottom surface of the electrical assembly part 600. With this structure, air flowing into the first space 101 from the room, after impacting the bottom surface of the electrical assembly part 600, can flow along the surface of the electrical assembly part 600 and upwards into the first space 101. That is, by utilizing the location of the heat dissipation guide 700, the air flowing into the first space 101 can sufficiently dissipate heat from the surface of the electrical assembly part 600.

[0181] like Figure 5 and Figure 9 As shown, the heat dissipation guide 700 can be formed as a tube with an opening of a preset size.

[0182] Although not illustrated, the heat dissipation guide 700 can also be formed as a simple opening. However, in this case, moisture present on the top surface of the base frame 130 may be discharged into the room through the heat dissipation guide 700, which may cause user dissatisfaction.

[0183] Therefore, the heat dissipation guide 700 is formed as a tube that protrudes upward from the base frame 130 and is open inside. That is, since the heat dissipation guide 700 protrudes from the top surface of the base frame 130, even if condensation accumulates on the top surface of the base frame 130, it can prevent condensation from leaking to the indoor floor through the heat dissipation guide 700.

[0184] Furthermore, since the heat dissipation guide 700 is formed as a tube, the indoor air has directionality as it passes through the heat dissipation guide 700 and can be expelled in the direction in which the heat dissipation guide 700 is facing.

[0185] The opening of the heat dissipation guide 700 can be formed to be open to a portion of the bottom surface of the electrical assembly part 600. Therefore, indoor air flowing in through the heat dissipation guide 700 can be directly supplied to the electrical assembly part 600.

[0186] The opening of the heat dissipation guide 700 can be formed as an elongated hole. That is, the heat dissipation guide 700 can be formed as an elongated hole with a length along the length direction of the bottom surface of the electrical assembly part 600. For example, the heat dissipation guide 700 can be formed as an opening with an elongated hole that is longer than the width of the bottom surface of the electrical assembly part 600 and shorter than the length of the bottom surface of the electrical assembly part 600 along the length direction of the bottom surface of the electrical assembly part 600. This ensures sufficient airflow and exhausts indoor air to the widest possible area of ​​the bottom surface of the electrical assembly part 600 to dissipate heat from the electrical assembly part 600.

[0187] On the other hand, the heat dissipation guide 700 is preferably not vertically opposite to the guide member 530, but rather staggered. That is, in order to allow the indoor air flowing into the first space 101 through the heat dissipation guide 700 to pass through as many parts of the first space 101 as possible, the heat dissipation guide 700 and the guide member 530 are preferably not opposite each other.

[0188] Therefore, the guide 530 is preferably formed on the upper part of either side based on the electrical assembly part 600, and the heat dissipation guide 700 is preferably formed on the lower part of the other side based on the electrical assembly part 600. Of course, considering the structure of the base frame 130, the heat dissipation guide 700 can also be formed on the lower part of the central side of the electrical assembly part 600 as shown in the embodiment.

[0189] The heat dissipation process of the electrical assembly part 600 of the dehumidifier in the above-described embodiment of the present invention will be described in detail below.

[0190] First, when the dehumidifier is not operating, the fan assembly 300 will not be driven. Therefore, not only is there no air suction in the upper space (the upper space of the partition frame) within the housing 100, but also in the lower space (the lower space of the partition frame, the first space, the second space, and the third space), so no indoor air is drawn in. Naturally, since the dehumidifier is not operating, the electrical assembly section 600 will not generate heat.

[0191] Furthermore, when the dehumidifier operates from the initial state described above, the compressor 230 of the dehumidification unit 200 operates.

[0192] Through the operation of the compressor 230, the refrigerant in the refrigeration cycle sequentially undergoes compression, condensation, expansion, and evaporation, and this process is repeated. As a result, the cold refrigerant passes through the evaporator 210, which constitutes the dehumidification section 200, and the hot refrigerant passes through the condenser 220, thereby exchanging heat with the air passing through the evaporator 210 and the condenser 220.

[0193] In addition, when the compressor 230 is activated, the fan assembly 300 is also activated.

[0194] The operation of the fan assembly 30 generates a low pressure and air suction between the opening (flare) of the fan housing 320 and the heat exchangers 210 and 220. Under the action of the air suction, indoor air is drawn in through the intake port 121 of the second peripheral housing 120.

[0195] Then, the drawn-in indoor air has its moisture separated as it passes through the evaporator 210 in the heat exchangers 210 and 220, and its temperature rises as it passes through the condenser 220.

[0196] Next, the air passing through the heat exchangers 210 and 220 flows into the fan housing 320 through the opening, then flows along the exhaust pipe 323 of the fan housing 320 and is supplied to the room through the exhaust port of the upper cover 140.

[0197] Therefore, the above process can be repeated to dehumidify indoor air.

[0198] On the other hand, as described above, during the dehumidification operation of the dehumidifier, the first space 101 in the lower space inside the housing 100 receives the air suction generated by the space in the upper space inside the housing 100 where the heat exchangers 210 and 220 are provided through the opening of the guide 530.

[0199] That is, a portion of the air suction generated by the operation of the fan assembly 300 is provided to the first space 101 through the guide 530, forming an airflow that causes the air in the first space 101 to flow to the fan assembly 300 through the guide 530.

[0200] In this situation, a negative pressure is generated inside the first space 101 to discharge air to the guide 530. Under the action of the negative pressure, the air in the room is drawn in through the heat dissipation guide 700 formed in the base frame 130 of the first space 101.

[0201] In addition, the air drawn into the room of the first space 101 is discharged to the bottom surface of the electrical assembly section 600 through the heat dissipation guide section 700 and guided by the flow.

[0202] Next, as the air rises and moves upward under the suction force provided by the upper corner of the first space 101, it flows along the surface of the second cover 622 that constitutes the electrical assembly part 600.

[0203] Thus, the electrical assembly 600 uses the air flowing along the surface of the second cover 622 to dissipate heat, thereby preventing the temperature of the circuit components 601 inside the housing 620 from rising excessively.

[0204] Furthermore, the air that has been cooled by the electrical assembly 600 flows to the guide 530 and is then supplied to the upper space inside the housing 100 via the guide 530. Thus, the air that cools the electrical assembly 600 is supplied to the fan assembly 300 located in the upper space inside the housing 100 and is then discharged into the room through the exhaust port 141 of the upper cover 140.

[0205] Thus, in the dehumidifier of this invention, since a heat dissipation guide 700 is formed in the base frame 130, the electrical assembly part 600 can be cooled even without an additional cooling fan for heat dissipation.

[0206] Furthermore, since the dehumidifier of this invention does not provide an additional cooling fan, the volume of the electrical assembly section 600 can be minimized.

[0207] In addition, in the dehumidifier of this invention, the opening of the first space 101 where the electrical assembly part 600 is provided is located as far away as possible from the opening where the air is discharged, and the electrical assembly part 600 is provided between the two openings, thereby improving the heat dissipation performance of the electrical assembly part 600.

[0208] on the other hand, Figure 18 This refers to the temperature distribution of the electrical assembly section when no heat dissipation guide is provided. Figure 19 This refers to the temperature distribution of the electrical assembly section when a heat dissipation guide section according to an embodiment of the present invention is provided.

[0209] Therefore, it can be known that when a heat dissipation guide section 700 is provided, the temperature reduction effect is approximately 20-30%.

[0210] On the other hand, the dehumidifier of this invention can also be implemented in various forms different from the embodiments described above. The various embodiments will be described below.

[0211] As another example of this utility model, such as Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the electrical assembly section 600 may be provided with a heat sink 630 for dissipating heat from the main PCB 610 disposed within the housing 620. The heat sink 630 may be formed to protrude to the outside of the second cover 622 of the housing 620. In this case, the heat sink 630 may be formed by a plurality of thin plates spaced apart from each other.

[0212] That is, an exposure hole 622a is formed in the second cover 622 in the housing 620, and the heat sink 630 is exposed to the outside of the second cover 622 through the exposure hole 622a. As a result, the air flowing along the surface of the housing 620 exchanges heat with the heat sink 630, thereby preventing the temperature of the various circuit components 601 of the main PCB 610 from rising excessively.

[0213] On the other hand, the heat sink 630 provided in the electrical assembly part 600 can be configured to improve heat exchange performance.

[0214] For example, such as Figure 17 As shown, the individual plates of the heat sink 630 can be formed to have different lengths from each other based on the inclination or curvature formed by the inner surface of the adjacent housing 100.

[0215] Therefore, the heat exchange area of ​​the heat sink 630 is maximized, thereby improving heat dissipation performance.

[0216] As another example of another aspect of this utility model, such as Figure 15 and Figure 16 As shown, a first opening may be formed in the housing 620 constituting the electrical assembly section 600. That is, by forming the first opening in the housing, hot air generated from the circuit component 601 can be forcibly discharged through the first opening 623 under the air suction of the fan assembly 300.

[0217] Such a first opening 623 can be formed on the top surface of the housing 620. Of course, the first opening 623 can also be formed on the side of the housing 620.

[0218] Additionally, a second opening 624 may be formed in the housing 620, which is open to allow air to flow into the first space 101.

[0219] The second opening 624 can be formed on the bottom surface of the housing 620. Thus, a portion of the air flowing out to the bottom surface of the housing 620 through the heat dissipation guide 700 can flow into the housing 620 through the second opening 624, directly dissipating heat from the various circuit components 601 of the main PCB 610.

[0220] As another example of this utility model, although not shown in the figure, in addition to the guide 530, the partition frame 500 may also have an opening for transmitting the air suction force generated in the upper space within the housing 100 to the first space 101.

[0221] Thus, the dehumidifier of this invention can be realized in various forms.

[0222] For the above description, although all the constituent elements constituting the embodiments of this utility model have been combined into one or more units to operate, this utility model is not limited to such embodiments. That is, within the scope of the purpose of this utility model, all its constituent elements may be selectively combined in more than one unit to operate.
