The cooled and dehumidified air enters the second heat exchange air passage 16 from the second inlet 38 of the heat exchanger 6, exchanges heat with the air flowing in from the first inlet 39, is heated, It leaves from the outlet 40 and is blown to the outside of the main body case 1 by the first blade portion 23.

  Further, when the blower 7 operates, in the second dehumidifying air path 36, the air taken into the main body case 1 from the first air inlet 2 by the first vane portion 23 is the upper surface of the heat exchanger 6. The heat is exchanged with the air that is cooled by the heat absorber 13 that flows into the first heat exchange air passage 15 from the first inlet 39 and flows through the second heat exchange air passage 16 from the second inlet 38 It is cooled and dehumidified, and exits from a first outlet 41 which is the lower surface of the heat exchanger 6. The cooled and dehumidified air is blown out of the main body case 1 by the first blade portion 23. At the time of cooling and dehumidifying, dew condensation water generated in the first heat exchange air path 15 of the heat exchanger 6 and the heat absorber 13 drips into the water collecting portion 8, and via the communication hole 42 of the water collecting portion 8, Drop it into the water collection tank 9.

  Further, when the blower 7 operates, the air taken into the main body case 1 from the second air inlet 3 by the second blade 24 in the warm air path 37 is blown to the radiator 11, and the radiator 11 is Heated through. The heated air is blown to the outside of the main body case 1 by the second blade portion 24.

The water collecting portion 8 covers the lower side of the heat absorber 13 and the heat exchanger 6, and forms a part of an air passage.

  The water collection tank 9 has a deep-bottomed bowl shape and is below the water collection unit 8, and is detachable from the main body case 1 below the heat absorber 13, the heat exchanger 6, the blower 7, and the radiator 11. Is located in Thereby, even when dew condensation water drips from the air blower 7, it can be collected in the water collection tank 9. The water collection tank 9 is disposed on one side of the main body case 1 in the left-right direction, and the compressor 10 is disposed on the other side of the main body case 1 in the left-right direction. The dimension in the front-rear direction of the body case 1 of the water collection tank 9 is a size smaller than the dimension from the front to the back of the body case 1. The lateral dimension of the water collection tank 9 in the main body case 1 is larger than the longitudinal dimension of the water collection tank 9 in the main body case 1. Thereby, the water storage capacity of the water collection tank 9 can be improved.

  The feature of the present embodiment is that the first dehumidifying air path 35 and the second dehumidifying air path 36 which are blown by the first blade portion 23 and pass through the heat absorber 13 inside the main body case 1 and the second dehumidifying air path A warm air path 37 is provided which is blown by the blades 24 and passes through the radiator 11, and the surface area of the radiator 11 is a point larger than the surface area of the heat absorber 13. The dimensions in the vertical direction and the lateral direction of the radiator 11 and the heat absorber 13 are the same, and the dimensions of the radiator 11 in the blowing direction blown by the second blade portion 24 are blown by the first blade portion 23 It is larger than the size of the heat sink 13 in the blowing direction.

  Thus, in addition to the first dehumidifying air path 35 having the heat exchanger 6 and the second dehumidifying air path 36, the warm air path 37 not having the heat exchanger 6 is provided. Decreases and the air volume increases. Furthermore, since the size of the radiator 11 in the blowing direction is larger than the size of the heat absorber 13 in the blowing direction blown by the first blade portion 23, the temperature of the dehumidified air rises, and the drying time of the laundry in the room Can be shortened.

  Specifically, the radiator 11 has a refrigerant pipe 14 and a heat sink 11 a. The refrigerant pipe 14 has a cylindrical shape made of copper, and has many horizontal portions 50 which meander in the vertical direction and extend in the horizontal direction, and a circular arc portion (not shown) in a circular arc shape. A large number of horizontal portions 50 are vertically arranged at predetermined intervals, and the ends of adjacent horizontal portions 50 are connected by an arc portion. The heat sink 11 a has a square flat plate shape, and a large number is fixed to the horizontal portion 50 of the refrigerant pipe 14. The heat sink 11 a has a surface in a direction perpendicular to the central axis direction of the horizontal portion 50 of the refrigerant pipe 14. Since the heat sink 11a is parallel to the blowing direction blown by the first blade portion 23, air flows along the surface of the heat sink 11a.

  As shown to FIG. 1, FIG. 3, the heat sink 13 has the refrigerant | coolant piping 14 and the heat absorption board 13a. The refrigerant pipe 14 has a cylindrical shape made of copper, and has a large number of horizontal portions 52 meandering in the vertical direction and extending in the horizontal direction, and an arc portion 53 having an arc shape. A large number of horizontal portions 52 are vertically arranged at predetermined intervals, and the ends of adjacent horizontal portions 52 are connected by an arc portion. The heat absorption plate 13 a has a rectangular flat plate shape, and a large number of heat absorption plates 13 a are fixed to the horizontal portion of the refrigerant pipe 14. The heat absorbing plate 13 a has a surface in the direction perpendicular to the central axis direction of the horizontal portion 52 of the refrigerant pipe 14. Since the heat absorbing plate 13a is parallel to the blowing direction blown by the first blade portion 23, air flows along the surface of the heat absorbing plate 13a.

  Here, the dimension of the heat sink 11a in the blowing direction (front-rear direction in the main body case 1) blown by the second wing portion 24 is the blowing direction (front-rear direction in the main body case 1) blown by the first wing portion 23. Larger than the dimension of the heat absorption plate 13a in FIG. As a result, the contact time between the air blown by the second blade portion 24 and the air blown by the second blade portion 24 becomes longer than the contact time between the air blown by the first blade portion 23 and the heat absorbing plate 13a, The temperature of the dehumidified air rises, and the drying time of the laundry in the room can be shortened.

Further, the dimensions of the heat sink 11a, the heat absorption plate 13a, and the heat exchanger in the vertical direction are the same.
Furthermore, the dimension from the heat sink 11a at one end of the horizontal portion 50 of the refrigerant pipe 14 in the radiator 11 to the heat sink 11a at the other end and the horizontal portion 52 of the refrigerant pipe 14 in the heat absorber 13 The dimension from the heat absorption plate 13a at one side end to the heat absorption plate 13a at the other side in the axial direction and the one side end to the other side in the axial direction of the horizontal portion 52 of the refrigerant pipe 14 in the heat exchanger 6 The dimensions up to the part are the same.

  As a result, the air passage shape in the direction perpendicular to the air blowing direction blown by the first blade portion 23 and the second blade portion 24 can be made the same. Dead space can be reduced.

  Further, the horizontal portion 52 of the refrigerant pipe 14 of the heat absorber 13 is in one row in the blowing direction blown by the first blade portion 23, and the horizontal portion 50 of the refrigerant pipe 14 of the radiator 11 is the second blade There are two more rows by one row than the number of rows of the horizontal portions 52 of the refrigerant piping 14 of the heat absorber 13 in the blowing direction blown by the portion 24. Furthermore, since the number of horizontal parts of the refrigerant piping of the radiator is larger than the number of horizontal parts of the refrigerant piping of the heat absorber, the heat dissipation plate 11a has a heat exchange efficiency with the refrigerant in the refrigerant piping compared to the heat absorption plate 13a. Can improve the temperature of the dehumidified air and shorten the drying time of the laundry in the room.

  The dehumidifying device according to the present invention is useful as a dehumidifying device for household use, office use, etc. for drying laundry in a room.
