  That is, dew condensation is performed at the heat absorber 10 and the heat exchanger 11, and the condensed water is collected by the funnel-shaped water collecting means 12a and flows into the water collection tank 12b.

  Next, the detailed structure of the precooling air passage will be described with reference to FIG. FIG. 3 is a perspective view of the configuration around the heat absorber and the air passage.

  As shown in FIG. 3, the pre-cooling air passage 60 includes an air passage 60a that starts from the side of the suction port 2b and reaches the upstream opening 18a via the side surface of the heat absorber 10 and the side surface of the heat exchanger 11, and The air passage 60b starts from the upper part of the suction port 2b and reaches the upstream opening 18a through the upper surface of the heat absorber 10.

  Air passage walls 81 are provided around the heat absorber 10, that is, on the upper surface and both side surfaces.

  The air passage wall 81 is further extended to both side surfaces of the adjacent heat exchanger 11 on both side surfaces. That is, the air passage wall 81 blocks the ventilation between the first dehumidifying passage 41 and the precooling air passage 60 between the heat absorber 10 and the heat exchanger 11, that is, the inner peripheral wall surface (first 1 side surface on the dehumidifying path side). Further, the outer peripheral wall surface of the precooling air passage 60 is formed by the inner surface of the main body case 1. The air passage wall 81 is made of a material capable of transferring heat between the first dehumidifying passage 41 and the precooling air passage 60 at least in a portion around the heat absorber 10, for example, a thin resin plate or metal of about 1 to 3 mm. It is a board.

  The heat absorber 10 has the refrigerant | coolant piping 101 comprised by the straight pipe | tube part 101a and the bending part 101b. The straight pipe portion 101a has fins formed of a plurality of flat metal plates for transmitting the heat of the refrigerant flowing through the refrigerant pipe 101 to the air passing through the heat absorber 10.

  The straight pipe portion 101 a and the fin of the heat absorber 10 are arranged in an internal space surrounded by the air passage wall 81. In other words, a portion A of the air passing through the first dehumidifying path 41 is provided so as to pass through the straight pipe portion 101a and the fin portion.

  On the other hand, the bent portion 101 b of the heat absorber 10 is arranged to project from the air passage wall 81 surrounding the heat absorber 10 to the precooling air passage 60. That is, the other part B of the air passing through the precooling air passage 60 of the second dehumidifying passage 51 is provided so as to pass through the air passage wall 81 around the heat absorber 10 and the pipe outer wall of the bent portion 101b.

  Next, the detailed structure of the heat exchanger 11 will be described with reference to FIG. FIG. 4 is an exploded perspective view of the heat exchanger.

  As shown in FIG. 4, the heat exchanger 11 has a configuration in which a plurality of synthetic resin plate bodies 13 that create a vertical air passage and a synthetic resin plate body 14 that forms a horizontal air passage are alternately superposed. ing.

  Further, a plurality of ribs 15 extending in the vertical direction are formed integrally with the plate body 13 at predetermined intervals on the surface of the synthetic resin plate body 13 that forms a vertical air passage. Since one surface of the rib 15 is in close contact with the back surface of the adjacent plate body 14, a vertical air path is formed by the surface of the plate body 13, the rib 15, and the back surface of the plate body 14.

  Similarly, a plurality of ribs 16 extending in the lateral direction are formed integrally with the plate body 14 at predetermined intervals on the surface of the synthetic resin plate body 14 that forms a lateral air passage. Since one surface of the rib 16 is in close contact with the back surface of the adjacent plate body 13, a lateral air path is formed by the surface of the plate body 14, the rib 16, and the back surface of the plate body 13.

  The vertical airway and the horizontal airway have independent airway spaces, that is, there is no air traffic.

  And the heat exchanger 11 comprised in this way becomes a substantially rectangular parallelepiped shape, and the opening part 17 in the 1st dehumidification path | route is as shown to the opposing long side side (right-and-left side in FIG. 3). The second dehumidifying path opening 18 is formed on the short side (upper and lower sides in FIG. 3) that are formed. Further, the downstream opening 30 on the short side is inclined with respect to the first dehumidification path 41, that is, the horizontal plane, and the inclination direction is a direction in which the opening surface of the downstream opening 30 faces the radiator 8 side. .

  Next, the operation of the dehumidifier will be described mainly with reference to FIG.

  The air sucked into the main body case 1 from the air suction port 2 by driving the blower 6 (part A of the air sucked from the suction port 2a) is the upstream opening of the heat absorber 10 and the heat exchanger 11. It passes through 17a and the first lateral passage, and is taken into the radiator 8 from the downstream opening 17b. Thereafter, the air is blown out of the main body case 1 from the air outlet 4 via the radiator 8 and the blower 6. That is, a part A of the air sucked from the suction port 2 a is blown out of the main body case 1 via the first dehumidifying path 41.

  A portion A of the air flowing through such a path is first cooled by the heat absorber 10, so that condensation occurs here, and the condensed water drops downward, and the funnel-shaped water collecting means 12 a. Collected and flowed into the water collection tank 12b.

  The dried air A after dropping the condensed water then passes through the first lateral passage from the upstream opening 17a of the heat exchanger 11, passes through the downstream opening 17b, and passes through the radiator 8; The air is blown out of the main body case 1 from the air outlet 4 through the blower 6. In this way, the indoor humidity can be reduced.

  On the other hand, the air sucked into the main body case 1 from the air suction port 2 by driving the blower 6 (the other part B of the air sucked from the suction port 2b) is the upstream opening 18a of the heat exchanger 11. From the air outlet 4 to the outside of the main body case 1 through the downstream opening 30, the radiator 8, and the blower 6. That is, the other part B of the air sucked from the suction port 2 b is blown out of the main body case 1 via the second dehumidification path 51. Since the downstream opening 30 is inclined toward the radiator 8 as described above, the air B generated from the downstream opening 30 flows to the radiator 8 smoothly.

  Since the horizontal first passage (passage through which part of air A passes) of the heat exchanger 11 and the vertical second passage (passage through which other part B of air passes) intersect, The air flowing through the first passage (a portion A of air) and the air flowing through the second passage (the other portion B of air) can exchange heat.

  Here, a part A of the air flowing through the first lateral passage of the heat exchanger 11 is cooled by passing through the heat absorber 10. Therefore, the portion A of the air can reduce the temperature of the other portion B of the air flowing through the second passage not passing through the heat absorber 10 due to the heat exchange action by the heat exchanger 11.

  Further, the other part B of the air passing through the precooling air passage 60 receives the cooling effect of the heat absorber 10 via the air passage wall 81. Furthermore, the cooling effect by the bending part 101b is also received. This is because the refrigerant having a temperature lower than room temperature passes through the bent portion 101b, so that the air temperature outside the bent portion 101b of the heat absorber 10 projecting into the precooling air passage 60 decreases. As a result, the temperature of the other part B of the air passing through the precooling air passage 60 is cooled to near the dew point temperature where condensation occurs.

  The other part B of the air cooled to near the dew point temperature flows into the second passage of the heat exchanger 11. The other part B of the air that has flowed into the heat exchanger 11 receives a cooling effect due to the heat exchange action of the heat exchanger 11, and the temperature drops to the dew point temperature or lower. The other part B of the air that has fallen below the dew point temperature causes condensation in the second passage of the heat exchanger 11.

  Here, in the conventional configuration, the air flowing into the heat exchanger 11 is at room temperature, and condensation does not occur unless the air is cooled to the dew point temperature. Therefore, cooling by the heat exchanger 11 starts the air inlet ( Condensation did not occur in the vicinity of the upstream opening 18a). However, in the configuration according to the present embodiment, the other part B of the air flowing into the second passage of the heat exchanger 11 is cooled to the vicinity of the dew point temperature by passing through the precooling air passage 60. Condensation can also occur at the air inlet (upstream opening 18a) of the second passage of the vessel 11.

  As a result, most of the cold heat received by the other part B of the air when passing through the heat exchanger 11 can be effectively utilized for latent heat removal, that is, condensation, instead of sensible heat removal of the other part B of the air. become. As a result, the amount of dew condensation in the heat exchanger 11 can be increased, so the dehumidifying device having the configuration according to the present embodiment can further enhance the dehumidifying effect.

  Further, a suction port 2b through which the other part B of the air is sucked is provided on the outer peripheral side adjacent to the suction port 2a into which a part A of the air is sucked. Therefore, the inflow amount of the air sucked from the suction port 2b can be increased by the attraction effect of the air sucked into the suction port 2a. That is, as shown in FIG. 5, an air flow 90 from the outside of the main body case 1 toward the suction port 2a is formed by the air flow sucked into the suction port 2a, and the air flow 90 is attracted by the viscosity of the air around the air flow 90. An induced flow 91 is formed. The second dehumidifying path can suck in more air by sucking the induced flow 91 from the suction port 2b provided on the outer peripheral side of the suction port 2a. Therefore, the amount of air passing through the second dehumidifying path increases and the amount of dew condensation in the heat exchanger 11 increases, so that the dehumidifying effect can be further enhanced. In other words, the dehumidifying device can be downsized if the same dehumidifying effect is obtained.

  With the above description, when the basic configuration and operation are understood, a specific configuration will be described.

  FIG. 6 is an exploded perspective view around the heat exchanger 11 of the dehumidifying device 3 according to the present exemplary embodiment. As shown in FIGS. 4 and 6, the heat exchanger 11 is formed by laminating a plurality of thin plate-like plates 13 and 14 that are heat transfer plates at a predetermined interval, and indoor air and heat absorption are stacked in the heat transfer plate stacking gap. The first outlet and the second passage are formed by alternately flowing the vessel outlet air. The heat exchanger 11 is fixed by a storage portion 70 that presses each of the heat transfer plates in the stacking direction.

  Specifically, the storage unit 70 includes a case 71 and a cover 72.

  The case 71 includes two side plate portions 73 and a case connecting portion 74. The two side plate portions 73 are vertically-rectangular flat plates facing the first direction, which is the stacking direction (horizontal direction) of the heat transfer plates, and are connected by a plurality of case connecting portions 74. The case connecting portion 74 has a rod shape extending in the first direction, and is provided on one side in the second direction orthogonal to the first direction to connect the two side plate portions 73. The space between the plurality of case connecting portions 74 is an air path. The case 71 is U-shaped with the other side in the second direction opened when viewed from above.

  The cover 72 includes two frame portions 75 and a cover connecting portion 76. The two frame portions 75 are vertically long rectangular flat plates facing the two side plate portions 73, and are connected by a plurality of cover connecting portions 76. The cover connecting part 76 has a bar shape extending in the first direction and connects the two frame parts 75. An air passage is formed between the plurality of cover connecting portions 76. The cover is fixed with a screw to the other side in the second direction of the two side plate portions 73 of the case.

  The heat exchanger 11 is sandwiched between two side plate portions 73 in a state where a plurality of heat transfer plates are stacked in the first direction, and the cover 72 connects the other side of the two side plate portions 73 in the second direction. Is done. Thereby, the heat exchanger 11 is fixed in the storage unit 70.

  As a result, the two side plate portions 73 sandwich the heat transfer plates from the stacking direction, and the pressing of each heat transfer plate is ensured, and by connecting the side plate portions 73 to each other by the case connecting portion 74, Since the deformation due to the reaction force of the pressing can be suppressed and the respective heat transfer plates can be reliably pressed against each other, the airtightness of the first air path and the second air path of the heat exchanger 11 is improved, and the wind Since it suppresses that a leak arises, the required air volume in each channel | path can be ensured, and dehumidification efficiency can be improved.

  The heat transfer plate has a convex portion on one surface and a concave portion on the other surface. When the heat transfer plates are stacked, the convex portion enters the concave portion of the adjacent heat transfer plate. The stacking completion dimension is a dimension in a state in which the heat transfer plates are stacked in the upward direction and the convex portion enters the concave portion of the adjacent heat transfer plate by gravity. The heat transfer plate is a thin plate-shaped resin component that is lightweight, so simply stacking the heat transfer plate upwards will not allow the protrusion to completely enter the recess, but there will be a slight gap between the recess and the protrusion.

In particular, the ribs 16 extend in the air blowing direction in the front-rear direction of the main body case 1. The rib 16, the case connecting part 74, and the cover connecting part 76 are arranged at the positions projected in the airflow direction.

  Thereby, the increase in ventilation resistance can be suppressed by disposing the spacing ribs serving as ventilation resistance and the positions where the cover coupling portion 76 and the case coupling portion 74 are projected in the ventilation direction. Therefore, a decrease in dehumidification efficiency can be suppressed.

  The case connecting portion 74 and the cover connecting portion 76 do not contact the heat exchanger 11, the heat absorber 10, and the radiator 8.

  Thereby, when the compressor 7 is operated, it is driven with vibration. The vibration is transmitted through the refrigerant pipe and is also propagated to the heat absorber 10 and the heat radiator 8. Since the part 74 does not contact the heat exchanger 11, the heat absorber 10, and the heat radiator 8, it is possible to suppress the transmission of vibration and suppress the generation of unpleasant chatter noise.

  Since the dehumidifying apparatus according to the present invention has a higher dehumidifying effect, it is extremely useful for dehumidifying indoor air and drying clothes.
