FIG. 3 schematically shows an example of the configuration of the condenser and connecting pipe of the heat exchange unit, and FIG. 4 schematically shows another example of the configuration of the condenser and connecting pipe of the heat exchange unit. It is.

  As shown in FIG. 1, a dehumidifier 1 including a heat exchange unit according to Embodiment 1 of the present invention includes a housing 10. The housing | casing 10 is formed so that it can become independent. The housing 10 is formed with a suction port 11 and an air outlet 12. The suction port 11 is an opening for sucking air from the outside to the inside of the housing 10. The suction port 11 is disposed on the back surface of the housing 10. The air outlet 12 is an opening for blowing air from the inside of the housing 10 to the outside. The air outlet 12 is disposed in the upper part of the housing 10.

  Inside the housing 10, an air passage that leads from the suction port 11 to the air outlet 12 is formed. A blower fan 21, a compressor 22 and a heat exchange unit are provided inside the housing 10. The blower fan 21 is disposed in the air path inside the housing 10. The blower fan 21 is for generating an air flow sucked from the suction port 11 and blown out from the blower outlet 12 through the air passage.

  A heat exchange unit is disposed between the blower fan 21 and the suction port 11 in the air passage inside the housing 10. The heat exchange unit includes a first condenser 30 and a heat exchanger 40. A first condenser 30 is disposed on the upstream side of the blower fan 21 in the air passage inside the housing 10. A heat exchanger 40 is disposed on the upstream side of the first condenser 30 in the air passage inside the housing 10. That is, the heat exchanger 40 is disposed adjacent to the first condenser 30. In this manner, the air sucked from the suction port 11 passes through the heat exchanger 40, the first condenser 30, and the blower fan 21 in this order, and the air path that blows out from the outlet 12 is the interior of the housing 10. Is formed.

  A predetermined interval is provided between the heat exchanger 40 and the first condenser 30. A mixing space 13 is formed between the heat exchanger 40 and the first condenser 30 thus spaced apart. Further, a bypass air passage 14 is formed inside the housing 10. The bypass air passage 14 is formed so that the air sucked from the suction port 11 bypasses the heat exchanger 40 and reaches the mixing space 13.

  The compressor 22 is for circulating the refrigerant through the heat exchange unit, that is, the first condenser 30 and the heat exchanger 40.

  Next, the configuration of the heat exchange unit and the air path will be described with reference to FIG. As shown in the figure, the heat exchanger 40 includes a second condenser 41 and an evaporator 42. The second condenser 41 is disposed on the first condenser 30 side in the heat exchanger 40. The evaporator 42 is disposed on the suction port 11 side in the heat exchanger 40. As described above, the mixing space 13 is formed between the heat exchanger 40 and the first condenser 30. Therefore, the second condenser 41 is arranged at a predetermined interval from the first condenser 30.

  When the blower fan 21 rotates, air is sucked into the housing 10 from the suction port 11. The flow of air sucked from the suction port 11 is divided into two hands indicated by arrows A and B shown in FIG. The air flow indicated by the arrow A passes through the heat exchanger 40, that is, the evaporator 42 and the second condenser 41, and reaches the mixing space 13. And it passes the 1st condenser 30 from the mixing space 13, passes through the ventilation fan 21, and is discharged | emitted from the blower outlet 12 to the exterior of the housing | casing 10. FIG.

  On the other hand, the air flow indicated by the arrow B passes through the bypass air passage 14 and bypasses the heat exchanger 40 to reach the mixing space 13. And in the mixing space 13, the air flow shown by the arrow A merges, and the air that has passed through the heat exchanger 40 and the air that has not passed through are mixed. The mixed air passes through the first condenser 30, passes through the blower fan 21, and is discharged from the blower outlet 12 to the outside of the housing 10.

  Each of the first condenser 30 and the second condenser 41 has a flat plate shape. Each of the first condenser 30 and the second condenser 41 is arranged such that a plane having a plate-like maximum area is substantially orthogonal to the air flow direction indicated by the arrow A. Accordingly, the first condenser 30 and the second condenser 41 are arranged in parallel.

  The first condenser 30 and the second condenser 41 are connected by a connection pipe 50. The connection pipe 50 guides the refrigerant that has passed through the first condenser 30 to the second condenser 41. The second condenser 41 and the evaporator 42, the evaporator 42 and the compressor 22, and the compressor 22 and the first condenser 30 are also connected by refrigerant piping. Therefore, the refrigerant sent from the compressor 22 flows through a cyclic path in which the refrigerant passes through the first condenser 30, the second condenser 41, and the evaporator 42 in this order and returns to the compressor 22 again. Yes.

  Next, the configuration of the first condenser 30, the second condenser 41, and the connection pipe 50 will be described with reference to FIGS. 3 and 4 schematically show a state in which the first condenser 30, the second condenser 41, and the connection pipe 50 are viewed from the side of the dehumidifier 1.

  First, FIG. 3 shows an example of the configuration of the first condenser 30, the second condenser 41, and the connection pipe 50. As shown in the figure, the connecting pipe 50 includes a first straight portion 51, a second straight portion 52, and a straddling portion 53.

  One end of the first straight part 51 is connected to the first condenser 30. A connecting portion between the first linear portion 51 and the first condenser 30 (hereinafter also referred to as “the refrigerant outlet of the first condenser 30”) is disposed at a lower portion on one side surface of the first condenser 30. The first straight portion 51 is arranged linearly and parallel to the first condenser 30 from the refrigerant outlet of the first condenser 30 upward. Accordingly, the first linear portion 51 is disposed in parallel to the first condenser 30 on the side of the first condenser 30.

  One end of the second straight part 52 is connected to the second condenser 41. A connecting portion between the second linear portion 52 and the second condenser 41 (hereinafter also referred to as “the refrigerant inlet of the second condenser 41”) is disposed at a lower portion on one side surface of the second condenser 41. The second straight part 52 is arranged linearly and in parallel with the second condenser 41 downward from the refrigerant inlet of the second condenser 41. Therefore, the second linear portion 52 is disposed in parallel to the second condenser 41 on the side of the second condenser 41. Moreover, the 1st linear part 51 and the 2nd linear part 52 are arrange | positioned so that it may become parallel.

  The straddling portion 53 connects the other end of the first straight portion 51 and the other end of the second straight portion 52. That is, one end of the straddling portion 53 is connected to the other end of the first straight portion 51. The straddling portion 53 extends from the connection portion with the first straight portion 51 to the second condenser 41 side. In the example shown in FIG. 3, the straddling portion 53 is linearly arranged from the connecting portion with the first straight portion 51 toward the diagonally upper side on the second condenser 41 side. The other end of the straddling portion 53 is connected to the other end of the second linear portion 52.

  The angle of the straddling portion 53 with respect to the first straight portion 51 and the second straight portion 52 and the length of the straddling portion 53 are such that the first straight portion 51 and the first condenser 30 are parallel to each other. One end is fixed to the refrigerant outlet of the first condenser 30, and one end of the second linear part 52 is connected to the refrigerant inlet of the second condenser 41 so that the second linear part 52 and the second condenser 41 are parallel to each other. The first condenser 30 and the second condenser 41 are adjusted in advance so that the first condenser 30 and the second condenser 41 are arranged at the interval D when the first condenser 30 and the second condenser 41 are arranged. The interval D is set in advance to a value suitable for securing the space required as the mixing space 13 described above between the heat exchanger 40 and the first condenser 30.

  In addition, as shown in FIG. 4, you may make the angle of the straddle part 53 with respect to the 1st linear part 51 and the 2nd linear part 52 a right angle. That is, in the example of FIG. 4, the straddling portion 53 is arranged in a horizontal straight line from the connecting portion with the first straight portion 51 toward the second condenser 41 side.

  Next, assembly of the heat exchange unit configured as described above will be described. When attaching the connecting pipe 50 to the first condenser 30 and the second condenser 41 in the assembly process of the heat exchange unit, the assembly operator first makes the first condenser 30 and the first linear portion 51 parallel, for example. Thus, the connecting pipe 50 is applied to the side surface of the first condenser 30. Then, one end of the connection pipe 50 is fixed to the refrigerant outlet of the first condenser 30 by, for example, welding.

  Next, the assembly worker assigns the connecting pipe 50 to the side surface of the second condenser 41 so that the second condenser 41 and the second linear portion 52 are parallel to each other. Then, the other end of the connection pipe 50 is fixed to the refrigerant inlet of the second condenser 41 by, for example, welding.

  As described above, the assembling worker simply aligns the connecting pipe 50 so that the first condenser 30 and the first straight portion 51 and the second condenser 41 and the second straight portion 52 are parallel to each other. The first condenser 30 and the second condenser 41 can be arranged in parallel and at a preset interval D. Therefore, the process of attaching the connecting pipe 50 in the production and assembly of the heat exchange unit including the two condensers of the first condenser 30 and the second condenser 41 and forming the mixing space 13 between the two condensers. Therefore, the first condenser 30 and the second condenser 41 can be easily and accurately arranged at an interval suitable for the mixing space 13. And the working efficiency at the time of manufacture and assembly of a heat exchange unit can be improved.

  In the example shown in FIGS. 3 and 4, the straddling portion 53 is linear. However, the straddling portion 53 may not be linear. That is, the straddling portion 53 may be bent in a curved shape, for example.

  Here, in the configuration shown in FIGS. 3 and 4, the connection pipe 50 has a point-symmetric shape with respect to the center of the straddling portion 53. That is, when the distance along the vertical direction from the refrigerant outlet of the first condenser 30 to the refrigerant inlet of the second condenser 41 is L, the vertical direction from the refrigerant outlet of the first condenser 30 to the center of the straddling portion 53. And the distance along the vertical direction from the refrigerant inlet of the second condenser 41 to the center of the straddling portion 53 are both L / 2. Further, the length of the first straight part 51 and the length of the second straight part 52 are also equal.

  Therefore, it is not necessary to substantially distinguish the first straight portion 51 and the second straight portion 52, the first straight portion 51 is fixed to the second condenser 41, and the second straight portion 52 is fixed to the first condenser 30. There is no problem even if fixed to. In other words, when manufacturing and assembling, there is no need to worry about the direction in which the connection pipe 50 is attached to the first condenser 30 and the second condenser 41. For this reason, the work efficiency at the time of manufacture and assembly of the heat exchange unit can be further improved.

  One end of the first straight part 51 is connected to the first condenser 30. A connection portion between the first straight portion 51 and the first condenser 30, that is, a refrigerant outlet of the first condenser 30 is disposed at a lower portion on one side surface of the first condenser 30. The first straight portion 51 is arranged linearly and parallel to the first condenser 30 from the refrigerant outlet of the first condenser 30 upward. Accordingly, the first linear portion 51 is disposed in parallel to the first condenser 30 on the side of the first condenser 30.

  The straddling portion 53 connects the other end of the first straight portion 51 and the refrigerant inlet of the second condenser 41. That is, one end of the straddling portion 53 is connected to the other end of the first straight portion 51. The straddling portion 53 extends from the connection portion with the first straight portion 51 to the second condenser 41 side. In the example shown in FIG. 5, the straddling portion 53 is arranged linearly from the connection portion with the first straight portion 51 toward the diagonally upper side on the second condenser 41 side. The other end of the straddling portion 53 is connected to the refrigerant inlet of the second condenser 41.

  The angle of the straddling portion 53 with respect to the first straight portion 51 and the length of the straddling portion 53 are such that one end of the first straight portion 51 is connected to the first condenser so that the first straight portion 51 and the first condenser 30 are parallel to each other. 30 and the other end of the straddle 53 is fixed to the refrigerant inlet of the second condenser 41 so that the first condenser 30 and the second condenser 41 are parallel to each other. The first condenser 30 and the second condenser 41 are adjusted in advance so as to be arranged at the interval D. The interval D is set in advance to a value suitable for securing the space required as the mixing space 13 described above between the heat exchanger 40 and the first condenser 30.

  In addition, as shown in FIG. 6, you may make the angle of the straddle part 53 with respect to the 1st linear part 51 a right angle.

  Next, assembly of the heat exchange unit configured as described above will be described. When the connecting pipe 50 is attached to the first condenser 30 and the second condenser 41 in the assembly process of the heat exchange unit, the assembly operator first makes the first condenser 30 and the first linear portion 51 parallel to each other. The connecting pipe 50 is assigned to the side surface of the first condenser 30. Then, the end of the connection pipe 50 on the first linear portion 51 side is fixed to the refrigerant outlet of the first condenser 30 by, for example, welding.

  Next, the assembling worker assigns the end of the connecting pipe 50 on the straddle 53 side to the refrigerant inlet of the second condenser 41 so that the first condenser 30 and the second condenser 41 are parallel to each other. Then, the end of the connecting pipe 50 on the straddling portion 53 side is fixed to the refrigerant inlet of the second condenser 41 by, for example, welding.

  Thus, the assembly operator aligns the connecting pipe 50 so that the first condenser 30 and the first linear portion 51 are parallel, and the first condenser 30 and the second condenser 41 are parallel. It is possible to arrange the first condenser 30 and the second condenser 41 at a preset interval D simply by doing so.
