  Further, in the main body case 1, a pre-cooling air passage leading to the heat exchanger 11 is provided by passing from the air suction port 2 around the heat absorber 10 to receive a cooling effect from the heat absorber 10.

  That is, the dehumidifying means 5 transmits the other part B of the air sucked from the air suction port 2, that is, the air sucked from the suction port 2 b, in addition to the first dehumidifying path 41, to the pre-cooled air path and the heat exchanger 11. There is provided a second dehumidifying path 51 that blows out of the main body case 1 from the air outlet 4 through the second passage and the radiator 8. The details of the pre-cooling air path will be described later.

  The heat exchanger 11 includes an opening 17 in the first dehumidifying path and an opening 18 in the second dehumidifying path.

That is, the opening 18 in the second dehumidifying path is provided in the second dehumidifying path 51, and connects the pre-cooled air path and the heat exchanger 11 on the upstream side and the lower part of the heat exchanger 11 and the radiator 8 on the downstream side. And concatenate. The water collecting means 12a has a funnel shape and is provided below the heat absorber 10 and the heat exchanger 11. Further, a water collecting tank 12b is disposed below the water collecting means 12a so as to be detachable from the main body case 1.

  In other words, dew is formed in 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 collecting tank 12b.

  Subsequently, the detailed structure of the pre-cooled 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 has an air passage 60 a starting from the side of the suction port 2 b and reaching the upstream opening 18 a via the side surface of the heat absorber 10 and the side surface of the heat exchanger 11, An air path 60b is formed from the upper part of the inlet 2b as a starting point to the upstream opening 18a via the upper surface of the heat absorber 10.

  An air path wall 81 is provided around the heat absorber 10, that is, on the upper surface and both side surfaces.

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

  The heat absorber 10 has a refrigerant pipe 101 composed of a straight pipe portion 101a and a bent portion 101b. The straight pipe portion 101a has a plurality of flat fins made of metal for transmitting heat of the refrigerant flowing through the refrigerant pipe 101 to air passing through the heat absorber 10.

  The straight pipe portion 101 a and the fins of the heat absorber 10 are arranged in an internal space surrounded by the air path wall 81. That is, 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 disposed so as to protrude from the air passage wall 81 surrounding the heat absorber 10 to the precooled air passage 60. In other words, another portion B of the air passing through the pre-cooling 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 outer pipe wall of the bent portion 101b.

  Subsequently, 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 structure in which a plurality of synthetic resin plates 13 for forming a vertical air passage and a plurality of synthetic resin plates 14 for forming a horizontal air passage are alternately superposed. ing.

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

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

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

  The heat exchanger 11 thus configured has a substantially rectangular parallelepiped shape, and the opening 17 in the first dehumidifying path is formed as shown on the long side (the left and right sides in FIG. 3) facing the heat exchanger 11. The second dehumidifying passage opening 18 is formed on the opposite short side (upper and lower sides in FIG. 3). Further, the downstream opening 30 on the short side is inclined with respect to the first dehumidifying 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 (a part A of the air suctioned from the suction port 2a) is an upstream opening of the heat absorber 10 and the heat exchanger 11. After passing through the first passage 17a and the horizontal passage, it 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 through 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.

  Then, a part A of the air flowing in such a path is first cooled by the heat absorber 10, so that dew condensation occurs here, and the dew condensation water drops downward and is collected by the funnel-shaped water collecting means 12a. It is collected and made to flow into the water collecting tank 12b.

  Further, the dried air A after the dew condensation water has been dropped passes from the upstream opening 17a of the heat exchanger 11 through the first horizontal passage, passes through the downstream opening 17b, and then 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. Thus, 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 portion B of the air sucked from the suction port 2b) flows into the upstream opening 18a of the heat exchanger 11. Then, the air passes through a vertical second passage, and is blown out of the main body case 1 from the air outlet 4 through the downstream opening 30, the radiator 8, and the blower 6. That is, another portion B of the air sucked from the suction port 2b is blown out of the main body case 1 via the second dehumidifying path 51. Since the downstream opening 30 is inclined toward the radiator 8 as described above, the air B flowing out of the downstream opening 30 flows to the radiator 8 smoothly.

  Since the first horizontal passage (the passage through which a portion of the air A passes) of the heat exchanger 11 and the second vertical passage (the passage through which the other portion B of the air passes) intersect, The air (the part A of the air) flowing through the first passage and the air (the other part B of the air) flowing through the second passage 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 part A of the air can lower the temperature of the other part B of the air flowing through the second passage not passing through the heat absorber 10 by the heat exchange action of the heat exchanger 11.

  Another portion B of the air passing through the pre-cooling air passage 60 receives the cooling effect of the heat absorber 10 via the air passage wall 81. Further, the cooling effect by the bent portion 101b is also received. This is because the refrigerant having a temperature lower than the room temperature passes through the bent portion 101b, so that the temperature of the air outside the bent portion 101b of the heat absorber 10 protruding into the pre-cooling air passage 60 decreases. As a result, the temperature of the other portion B of the air passing through the pre-cooling air passage 60 is cooled to around the dew point temperature at which dew condensation occurs.

  Another portion B of the air cooled to around the dew point temperature flows into the second passage of the heat exchanger 11. The other portion 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 its temperature drops to a temperature equal to or lower than the dew point temperature. The other portion B of the air that has dropped to the dew point temperature or lower causes dew 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 dew condensation does not occur unless the air is cooled to the dew point temperature. Therefore, the air inlet of the heat exchanger 11 where cooling by the heat exchanger 11 starts ( Dew condensation did not occur near the upstream opening 18a). However, in the configuration according to the present embodiment, the other portion B of the air flowing into the second passage of the heat exchanger 11 is cooled to near the dew point temperature by passing through the pre-cooling air passage 60, so that heat exchange is performed. Dew condensation can also occur at the air inlet (upstream opening 18a) of the second passage of the vessel 11.

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

  Further, a suction port 2b into which another part B of the air is sucked is provided on an outer peripheral side adjacent to the suction port 2a into which a part A of the air is sucked. Therefore, the amount of inflow of 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 sucked into the suction port 2a forms an air flow 90 from the outside of the main body case 1 to the suction port 2a, and around the air flow 90 is attracted by the viscosity of the air. An induced flow 91 is formed. By sucking the induced flow 91 from the suction port 2b provided on the outer peripheral side of the suction port 2a, the second dehumidifying path can suck more air. 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, if the same dehumidifying effect is obtained, the size of the dehumidifying device can be reduced.

  Now that the basic configuration and operation have been understood from the above description, a specific configuration will be described.

  FIG. 6 is an exploded perspective view around the heat exchanger 11 of the dehumidifier 3 according to the present embodiment. As shown in FIGS. 4 and 6, the heat exchanger 11 is configured by laminating a plurality of thin plate-like plates 13 and 14, which are heat transfer plates, at a predetermined interval. A first passage and a second passage are formed by alternately flowing the container outlet air. The heat exchanger 11 is fixed by a housing 70 that presses each of the heat transfer plates in the stacking direction.

  The storage section 70 specifically 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 in the shape of a vertically long rectangular flat plate facing the first direction which is the lamination 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 a second direction orthogonal to the first direction, and connects the two side plate portions 73. An air path is provided between the plurality of case connecting portions 74. The case 71 has a U-shape that is open on the other side in the second direction when viewed from above.

  The cover 72 includes two frame portions 75 and a cover connecting portion 76. The two frame portions 75 have a vertically long rectangular flat plate shape facing the two side plate portions 73, and are connected by a plurality of cover connecting portions 76. The cover connecting portion 76 has a rod shape extending in the first direction and connects the two frame portions 75. An air path is provided between the plurality of cover connecting portions 76. The cover is fixed to the other side of the two side plates 73 of the case in the second direction by screws.

  The heat exchanger 11 is sandwiched between the 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 section 70.

  Thereby, the two side plate portions 73 sandwich the heat transfer plate from the laminating direction, ensuring the pressing of each heat transfer plate and connecting the side plate portions 73 by the case connecting portion 74, Deformation due to the reaction force of the pressing can be suppressed, and each heat transfer plate can be reliably pressed, so that the airtightness of the first air passage and the second air passage of the heat exchanger 11 is improved, Since the occurrence of leakage is suppressed, the required air volume in each passage can be secured, and the dehumidifying efficiency can be improved.

  Further, 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 portions enter the concave portions of the adjacent heat transfer plates. The stacking completed dimension is a dimension in a state in which the heat transfer plates are stacked in the upward direction, and the convex portions enter the concave portions of the adjacent heat transfer plates due to gravity. Since the heat transfer plate is a thin plate-shaped resin component and lightweight, simply stacking the heat transfer plate in the upward direction does not allow the convex portion to completely enter the concave portion, leaving a slight gap between the concave portion and the convex portion. Have. It is the storage section 70 that presses each of the heat transfer plates in the stacking direction and reduces this gap. The dimension between the side plate parts 73 of the storage part 70 is smaller than the lamination completion dimension in which the heat transfer plates are laminated in the upward direction.
