That is, the opening 18 in the second dehumidification path is provided in the second dehumidification path 51, and the precooling air path and the heat exchanger 11 are provided on the upstream side, and the lower part of the heat exchanger 11 and the radiator 8 on the downstream side. And The water receiving means 12 a has a funnel shape and is provided below the heat absorber 10 and the heat exchanger 11. Further, a tank 12b is detachably disposed on the main body case 1 below the water receiving means 12a.

  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 receiving means 12a and flows into the 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 receiving means 12a. Collected and flowed into the 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.

  Now that the basic configuration and operation have been understood, the specific configuration will be described with reference to FIG.

  The feature in this embodiment is the drain hole 70 provided in the water receiving means 12a.

  The water receiving means 12 a has a bowl shape with an upper opening, and is installed below the heat exchanger 11 and the heat absorber 10. The water receiving means 12 a receives condensed water generated in the first passage of the heat exchanger 11 and the heat absorber 10 and also serves as a part of the second dehumidifying path 51. When viewed from above, the water receiving means 12 a is slightly larger than the heat absorber 10, the heat exchanger 11, and the radiator 8.

  A tank 12b for storing condensed water is provided below the water receiving means 12a. The water receiving means 12 a is provided with a drain hole 70 for extracting condensed water from the water receiving means 12 a to the tank 12 b, and this drain hole 70 is disposed at the lower part of the heat exchanger 11.

  Thereby, since the drain hole 70 becomes the lowest point of the water receiving means 12a, an air passage space is formed at the outlet portion of the heat exchanger 11 of the second dehumidifying passage 51, and the heat exchanger 11 of the second passage. Since the bending of the air path to the radiator 8 is relaxed at the outlet and the ventilation resistance is reduced, the dehumidification efficiency can be increased by reducing the air path resistance and increasing the air volume.

  When the component parts are configured as in the present embodiment, since the air flows into the radiator 8 from the vertically downward wind direction at the second path outlet of the heat exchanger 11, the wind direction is changed by about 90 degrees, Need to change direction to direction. At that time, excessive wind path resistance is applied to change the wind direction.

  The drain hole 70 arranged in the water receiving means 12a needs to collect condensed water, and therefore needs to be arranged at the lowest point of the water receiving means 12a. As described above, by arranging the drain hole 70 in the lower part of the heat exchanger 11, an airflow space is inevitably formed in the lower part of the heat exchanger 11, that is, in the lower part of the first path of the heat exchanger 11. It is formed and the bending of the air path can be eased. As a result, the ventilation resistance is reduced, so that the dehumidification efficiency can be increased by increasing the air volume.

  Further, the drain hole 70 is disposed on the downstream side of the second dehumidification path 51 at the lower part of the heat exchanger 11 in the water receiving means. The water receiving means 12 a has an inclined surface so that the condensed water flows toward the drain hole 70. That is, the inclined surface is inclined downward as it goes from the heat absorber 10 toward the radiator 8.

  Thereby, since a downward slope is formed toward the drain hole 70 of the water receiving means 12a, an air passage space is formed at the outlet of the heat exchanger 11 of the second dehumidifying path 51, and heat exchange of the second path is performed. Since the bending of the air path to the radiator 8 is relaxed at the outlet of the radiator 11 and the ventilation resistance is reduced, the dehumidification efficiency can be increased by reducing the air path resistance and increasing the air volume.

(Embodiment 2)
In FIG. 6, the same components as those in FIG. The difference from the first embodiment is the position of the drain hole 70 provided in the water receiving means 12a in FIG.

  As shown in FIG. 6, the water receiving means 12 a includes a partition portion 71 that partitions an outlet portion of the heat absorber 10 in the first dehumidifying path 41 and a second path outlet portion of the heat exchanger 11 in the second dehumidifying path 51. ing. The partition portion 71 has a plate shape extending downward from between the heat absorber 10 and the heat exchanger 11. Between the lower end part of the partition part 71 and the water receiving means 12a, the space which is the extent to which dew condensation water flows is provided. And the drain hole 70 which leads dew condensation water from the water receiving means 12a to the tank 12b is arrange | positioned in the lower part of the heat absorber 10, ie, the upstream of the 1st dehumidification path | route 41 of the partition part 71. FIG.

  In the dehumidifying air passage, as shown in FIG. 7, the air that flows in from the intake air at the atmospheric pressure of the outside air is finally subjected to the air passage resistance of each component while expanding the pressure difference from the atmosphere. It will be sucked into the blower 6. The greater the pressure difference from the atmosphere, the greater the amount of air leakage when there is an opening communicating with the atmosphere at that portion.

  The water receiving means 12a needs to be provided with a drain hole 70 for leading accumulated water droplets to the tank 12b. However, the water receiving means 12a has an opening that communicates with the atmosphere, and air outside the air passage is caused by a pressure difference from the atmospheric pressure at the opening. It will flow in and dehumidification performance will fall.

  Therefore, as described above, by installing the drain hole 70 below the heat absorber 10, the pressure difference from the atmospheric pressure can be reduced without being affected by the pressure drop due to the air path pressure loss of the heat absorber 10. Thus, it is possible to provide an efficient dehumidifying device that can suppress the ingress of air from the drain hole 70 and can suppress a decrease in the dehumidifying capacity.

(Embodiment 3)
In FIG. 8, the same components as those in FIG. The difference from the second embodiment is the position of the drain hole 70 provided in the water receiving means 12a in FIG.

As shown in FIG. 8, a drain hole 70 for leading condensed water from the water receiving means 12 a to the tank 12 b is arranged on the windward side of the heat absorber 10, that is, on the air inlet 2 side in the main body case 1.
Thereby, since the drain hole 70 is provided outside the dehumidifying path, it is possible to suppress the ingress of air from the drain hole 70 and to provide an efficient dehumidifying device capable of suppressing a decrease in the dehumidifying capacity. be able to.

  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.
