[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters, and redundant description will not be repeated.

[0010] The appearance and internal structure of a dehumidifier 1 according to an embodiment of the present invention will be described with reference to Figs. 1 to 3. Fig. 1 is an external perspective view of the dehumidifier 1 according to this embodiment. Figs. 2 and 3 are views showing the internal structure of the dehumidifier 1 according to this embodiment. Fig. 2 is basically a side view of the dehumidifier 1 according to this embodiment, but for ease of visualization, the desiccant rotor 50 and the heating section 52 are shown as perspective views.

[0011] FIG. 3 is also a side view of the dehumidifier 1 according to this embodiment, but for ease of visualization, the desiccant rotor 50 and the heating section 52 are shown in a perspective view.

[0012] Further, as shown in FIG. 1, the front side of the dehumidifier 1 may be referred to as the front side of the dehumidifier 1, and the rear side of the dehumidifier 1 may be referred to as the rear side of the dehumidifier 1.

[0013] As shown in FIG. 1, the dehumidifier 1 includes a housing 2, an air inlet 3, and an air outlet 4.

[0014] The housing 2 is a hollow member.

[0015] The intake port 3 is formed, for example, on the top surface of the housing 2. As shown in Fig. 2, the intake port 3 takes in air outside the housing 2 as intake air A1. The intake port 3 may be disposed, for example, at the upper and left-right center on the rear surface of the housing 2. The intake port 3 communicates between the inside and outside of the housing 2.

[0016] The exhaust port 4 discharges the exhaust air B2. The exhaust port 4 is formed, for example, on the side or bottom surface of the housing 2. The exhaust port 4 communicates the inside and outside of the housing 2. The exhaust port 4 releases the exhaust air B1 inside the housing 2 to the outside of the housing 2. The exhaust port 4 may be located at a location other than the side surface of the housing 2.

[0017] The dehumidifier 1 includes, in addition to the external components (the housing 2, the intake port 3, and the exhaust port 4) described in FIG. 1, a dehumidifier section 5, a tank 6, and a fan 7 as internal components.

[0018] The dehumidification unit 5 has a function of removing moisture C1 (hereinafter, may be referred to as water vapor C1) from the intake air A1 containing moisture. Hereinafter, the moisture C2, the moisture C3, the moisture C4, and the moisture C5 may be referred to as water vapor C2, the moisture C3, and the moisture C5, respectively.

[0019] The tank 6 stores the condensed water D1 (condensed water D2) generated by cooling the high-temperature water vapor C1 removed from the intake air A1 by the dehumidifying section 5.

[0020] The fan 7 takes in intake air A1 from outside the dehumidifier 1. The fan 7 may be arranged near the intake port 3. The fan 7 may circulate the intake air A2 (intake air A3, intake air A4) inside the dehumidifier 1. The fan 7 may be arranged in an air path through which the intake air A2 (intake air A3, intake air A4) inside the dehumidifier 1 circulates. The fan 7 exhausts exhaust air B1 (exhaust air B2) to the outside of the dehumidifier 1. The fan 7 may be arranged near the exhaust port 4.

[0021] The principle by which the dehumidifier 1 dehumidifies the intake air A1 will be described below.

[0022] The dehumidification unit 5 includes a desiccant rotor 50 , a heat exchanger 51 , a heating unit 52 , and a fan 53 .

[0023] The heat exchanger 51 exchanges heat between the water vapor C1 (water vapor C2, water vapor C3) and air (intake air A1 (intake air A2, intake air A3, intake air A4)) to cool the water vapor C1 (water vapor C2, water vapor C3). The heat exchanger 51 is composed of a heat exchange pipe 510.

[0024] The desiccant rotor 50 adsorbs moisture (humidity C1) contained in the intake air A1 (intake air A2, intake air A3, intake air A4).

[0025] The desiccant rotor 50 may be formed into a cylindrical or panel shape. For example, a highly hygroscopic material such as silica gel or zeolite is used for the desiccant rotor 50. The desiccant rotor 50 is rotated by a motor (not shown).

[0026] The heat exchanger 51 cools the water vapor C2 desorbed from the desiccant rotor 50.

[0027] The desiccant rotor 50 and the heat exchanger 51 are provided along the vertical direction.

[0028] The heat exchanger 51 indirectly brings high-temperature moisture C3, moisture C4, and moisture C5 branched off from the high-temperature moisture C2 into contact with the low-temperature intake air A2 (intake air A3, intake air A4), thereby condensing the water vapor C3 (water vapor C4, water vapor C5) and obtaining condensed water D1 (condensed water D2).

[0029] Tank 6 is provided to the side of dehumidification section 5 and below heat exchanger 51, and stores condensation water D1 (condensation water D2) condensed in heat exchanger 51. By providing tank 6 to the side of dehumidification section 5 and below heat exchanger 51, it is possible to utilize the free space in dehumidifier 1 and to increase the size or capacity of tank 6. Furthermore, by providing tank 6 to the side of dehumidification section 5 rather than below it, it is possible to reduce the height of dehumidifier 1.

[0030] According to this embodiment, it is possible to obtain a dehumidifier 1 in which the tank 6 is enlarged while the height is kept low.

[0031] The heat exchanger 51 may be provided on the upper part of the dehumidification unit 5 .

[0032] According to this embodiment, it is possible to obtain a dehumidifier 1 in which the tank 6 is enlarged while the height is further reduced.

[0033] When the dehumidifier 1 is placed on a horizontal surface, the air intake 3, the dehumidifying section 5, and the air exhaust 4 may be arranged in this order from the upper side to the lower side in the vertical direction.

[0034] The heating section 52 heats the dry circulating air E2. The circulating air E1 (circulating air E2) separated from the heat exchanger 51 is heated by the heating section 52 and ventilated by the fan 53 to the desiccant rotor 50 as high-temperature circulating air E3.

[0035] The moisture C1 adsorbed by the desiccant rotor 50 is taken into the high-temperature circulating air E3 by the fan 53. The circulating air E4 containing the moisture C2 passes through the heat exchange pipe 510 and is supplied again to the vicinity of the fan 7.

[0036] The heating unit 52 may heat the desiccant rotor 50. By the heating unit 52 heating the desiccant rotor 50, the moisture C1 adsorbed by the desiccant rotor 50 is released into the circulating air E3 proceeding to the heat exchanger 51. The desiccant rotor 50 is dried and regenerated, and adsorbs moisture C1 again from the intake air A2 (intake air A3, intake air A4) while rotating.

[0037] The heat exchange pipe 510 further includes a direction changing portion 5101 and a hole portion 5102 .

[0038] The direction changing portion 5101 is formed by changing the direction of the heat exchange pipe 510, which is formed extending upward from the desiccant rotor 50, to a lateral direction (horizontal direction) and further extending in the lateral direction (horizontal direction).

[0039] The direction changing unit 5101 is composed of, for example, three heat exchange pipes 510. The circulating air E4 containing the moisture C2 transported upward by the heat exchange pipes 510 is changed in direction laterally by the direction changing unit 5101. The circulating air E4 containing the moisture C2 is transported near the fan 7 by the direction changing unit 5101.

[0040] The intake air A1 taken in from the outside of the dehumidifier 1 by the fan 7 passes between the three direction changing parts 5101 as intake air A2, intake air A3, and intake air A4.

[0041] At this time, the intake air A2 absorbs heat from the high-temperature circulating air E5 containing moisture C3 transported inside the direction changing portion 5101. The circulating air E5 absorbs heat and condenses. Therefore, the moisture C3 becomes condensed water D3.

[0042] Similarly, the intake air A3 absorbs heat from the high-temperature circulating air E6 containing moisture C4 transported inside the direction changing portion 5101. The circulating air E6 absorbs heat and condenses. As a result, the moisture C4 becomes condensed water D4.

[0043] The intake air A4 absorbs heat from the high-temperature circulating air E7 containing moisture C5 transported inside the direction changing portion 5101. The circulating air E7 absorbs heat and condenses. As a result, the moisture C5 becomes condensed water D5.

[0044] The condensed water D3, the condensed water D4, and the condensed water D5 become the condensed water D1, which is discharged from the heat exchange pipe 510, and become the condensed water D2, which is stored in the tank 6.

[0045] The circulating air E5, circulating air E6, and circulating air E7, which have become dry as a result of the moisture C3, moisture C4, and moisture C5 turning into condensed water D3, condensed water D4, and condensed water D5, respectively, leave the direction changing portion 5101 and enter the circulation piping 5100 through the hole 5102, and become dry circulating air E1. The hole 5102 is opened in the upper portion of the heat exchange piping 510. Therefore, the condensed water D1 does not flow from the hole 5102 into the circulation piping 5100, and only the dry circulating air E1 is transported through the circulation piping 5100.

[0046] The dry circulating air E2 transported inside the circulation pipe 5100 is heated by the heating section 52 and becomes high-temperature circulating air E3.

[0047] The high-temperature circulating air E3 is again passed through the desiccant rotor 50 by the fan 53, where it absorbs the moisture C1 and becomes circulating air E4 containing high-temperature moisture C2.

[0048] This is the principle by which the dehumidifier 1 dehumidifies the intake air A1.

[0049] 2, the tank 6 is disposed below the heat exchanger 51 of the dehumidifier 5. In the dehumidifier 1, the tank 6 is disposed beside the heat exchanger 51 of the dehumidifier 5.

[0050] As described above, when the dehumidifier 1 is placed on a horizontal surface, the dehumidifier unit 5 may be arranged such that the heat exchange pipe 510 and the desiccant rotor 50 are arranged in this order from the upper side to the lower side in the vertical direction.

[0051] The dehumidifier 1 of this embodiment shown in Figure 3 has the same components as the dehumidifier 1 of this embodiment described in Figure 2, but the positional relationship between the components is partially different from that of the dehumidifier 1 of this embodiment described in Figure 2.

[0052] As shown in FIG. 3, in the dehumidifier 1, the desiccant rotor 50 is disposed above the heat exchanger 51 in the vertical direction.

[0053] The exhaust port 4 is disposed at the upper part of the desiccant rotor 50 in the vertical direction.

[0054] The circulating air E2 that has been heat exchanged inside the heat exchanger 51 with the intake air A1 taken in from the intake port 3 passes through the circulation piping 5100, the heating section 52 and the desiccant rotor 50, receives water vapor C1 from the desiccant rotor 50, and returns to the inside of the heat exchanger 51.

[0055] The circulation pipe 5100 may be connected to the upper part of the heat exchanger 51 in the vertical direction.

[0056] Next, the configuration of the heat exchange piping 510 of the dehumidifier 1 according to this embodiment will be further described with reference to Figures 4A and 4B. Figures 4A and 4B are diagrams showing the heat exchange piping 510 of the dehumidifier 1 according to this embodiment.

[0057] As shown in FIG. 4A, the direction changing unit 5101 changes the direction of the water vapor C1 (water vapor C2, water vapor C3) flowing inside the heat exchange pipe 510.

[0058] According to this embodiment, the water vapor C1 (water vapor C2, water vapor C3) flowing inside the heat exchange pipe 510 can be brought closer to the intake air A1.

[0059] As shown in Figures 4A and 4B, the heat exchange pipe 510 has a plurality of direction change parts 5101 arranged in the vertical direction (up and down direction). However, as another example, as shown in Figures 6A and 6B, the heat exchange pipe 510 may have a plurality of direction change parts 5101 arranged in the horizontal direction.

[0060] The heat exchange pipe 510 may have a plurality of direction changing portions 5101 .

[0061] According to this embodiment, the surface area of ​​the heat exchange pipe 510 is increased, and heat can be exchanged efficiently.

[0062] That is, as shown in Fig. 4A, circulating air E4 containing moisture C2 contained in the desiccant rotor 50 passes through the heat exchange pipe 510, enters the direction changing section 5101, and becomes circulating air E5. Moisture C3 in the circulating air E5 loses heat to intake air A1 (intake air A2, intake air A3, intake air A4), becomes condensed water D3, and is drained to the dew receiving section 5103 shown in Fig. 4B. The condensed water D1 received by the dew receiving section 5103 is stored in the tank 6 as condensed water D2.

[0063] The heat exchange pipe 510 is formed to meander due to the direction changing portion 5101. Therefore, the intake air A1 (intake air A2, intake air A3, intake air A4) taken in by the fan 7 has multiple opportunities to indirectly take heat from the circulating air E5. Therefore, the moisture C2 easily becomes condensed water D3, and the recovery efficiency of the condensed water D1 and the condensed water D2 can be improved.

[0064] The direction changing unit 5101 may change the direction of the water vapor C3 along the vertical direction.

[0065] Therefore, the moisture C3 is more likely to change into the condensed water D3 more efficiently. Therefore, the condensed water D1 and the condensed water D2 can be stored in the tank 6 more efficiently.

[0066] That is, as shown in FIGS. 4A and 4B, the direction changing parts 5101 can be disposed at a plurality of positions in the middle of the heat exchange pipe 510 in the vertical direction (up and down direction).

[0067] After passing near the fan 7, the heat exchange pipe 510 extends vertically downward, has its direction changed by the first direction change section 5101, and passes again through the ventilation path of the intake A2 (intake A3, intake A4) by the fan 7.

[0068] The heat exchange pipe 510 is further changed in direction by the second and subsequent direction changing portions 5101, extends while inclining vertically downward, and passes again through the ventilation path of the intake A2 (intake A3, intake A4) by the fan 7.

[0069] 5A and 5B are schematic diagrams showing modified examples of the shape of the heat exchange pipe 510 of the heat exchanger 51. In FIG.

[0070] As shown in FIGS. 5A and 5B, the heat exchange piping 510 may have a hole 5102 provided in the middle between both ends of the heat exchange piping 510 .

[0071] According to this embodiment, even if the heat exchange pipe 510 is curved in the vertical direction, the condensed water D1 and the condensed water D2 can be efficiently stored in the tank 6.

[0072] The dew receiving portion 5103 is provided below the hole 5102, receives the condensed water D1 flowing out from the hole 5102, and guides it to the side of the dehumidifying portion 5.

[0073] According to this embodiment, the condensed water D1 and the condensed water D2 leaking from the hole 5102 can be efficiently stored in the tank 6.

[0074] The heat exchange piping 510 shown in FIG. 5A may be formed to extend vertically from an upper side to a lower side, and then a hole 5102 may be formed at the lowest point where the piping turns to extend vertically from the lower side to the upper side.

[0075] In the heat exchange pipe 510, the circulating air E5 containing moisture C3 descends vertically from the upper side to the lower side, and the moisture C3 changes into condensed water D3, which leaks from the hole 5102 to the dew receiving portion 5103.

[0076] The heat exchange pipe 510 shown in FIG. 5B may be formed so as to curve and meander from the upper side in the vertical direction to the lower side in the vertical direction, and then a hole 5102 may be formed at the lowest point.

[0077] In the heat exchange pipe 510, the circulating air E5 containing moisture C3 descends vertically from the upper side to the lower side, and the moisture C3 changes into condensed water D3, which leaks out from the hole 5102 to the dew receiving portion 5103.

[0078] Next, Fig. 6A shows the internal structure of a dehumidifier 1 according to another embodiment. Fig. 6A is a schematic diagram of the internal structure of the dehumidifier 1 according to another embodiment, viewed from the front. Fig. 6B shows the configuration of heat exchange piping 510 of the dehumidifier 1 according to another embodiment. Fig. 6B is a schematic diagram of the internal structure of the dehumidifier 1 according to another embodiment, viewed from above.

[0079] As described above, the heat exchange piping 510 shown in FIGS. 6A and 6B has a plurality of direction change portions 5101 arranged in the horizontal direction.

[0080] As shown in FIG. 6A, the circulating air E4 containing the moisture C2 that was contained in the desiccant rotor 50 passes through the heat exchange pipe 510, enters the direction changing section 5101, and becomes the circulating air E5.

[0081] The moisture C3 in the circulating air E5 loses heat to the intake air A1 (intake air A2, intake air A3, intake air A4) and becomes condensed water D3.

[0082] The heat exchange pipe 510 may be inclined as shown in FIG. 4A so that the condensed water D3 can easily flow.

[0083] The dew condensation water D3 flows out from a hole 5102 provided in the heat exchange pipe 510 and is guided to a dew receiving portion 5103.

[0084] The condensed water D1 received by the dew receiving portion 5103 is stored in the tank 6 as condensed water D2.

[0085] The direction changing unit 5101 changes the direction of the water vapor C3 along the horizontal direction.

[0086] According to this embodiment, the intake air A1 sucked in through the intake port 3 arranged in the upper part of the dehumidifier 1 can be dehumidified suitably.

[0087] As shown in FIG. 6B, the orientation change section 5101 has an n-th orientation change section 5101 and an (n+1)th orientation change section 5101.

[0088] The heat exchange pipes 510 connecting the n-th direction change section 5101 and the (n+1)-th direction change section 5101 each have a hole 5102 disposed therein.

[0089] The multiple dew receiving portions 5103 are separately connected to the respective holes 5102 and collect the condensation water D3 leaking from the respective holes 5102.

[0090] The tank 6 is disposed in a lower portion within the housing 2. The tank 6 is detachably stored in the housing 2. The tank 6 stores the water generated by the dehumidifier 1.
