The power supply board 8, the control board 9, the reactor 10, and the blower motor 11 are provided on the front side of the dehumidifier. FIG. 3 shows a state where the reactor 10 and the blower motor 11 are exposed.

  As shown in FIG. 3, one end of the AC power line 7 is connected to the power board 8. The other end of the AC power line 7 is connected to a power plug (not shown). The power plug is connected to an AC power source (not shown). The AC power line 7 is wired along the right side surface as viewed from the front side of the dehumidifier. The AC power supply line 7 along the right side surface is wired at a height near the lower end of the dehumidifier to the vicinity of the front surface. The AC power supply line 7 along the right side surface extends from the vicinity of the front surface to the power supply board 8 so as to extend upward.

  A reactor 10 is connected to the power supply substrate 8. The control board 9 is connected to the power supply board 8. A compressor and a blower motor 11 are connected to the control board 9.

  When the power plug is connected to an AC power supply, an AC voltage is supplied to the power supply substrate 8. For example, a converter circuit is formed on the power supply substrate 8. The converter circuit converts an AC voltage supplied from an AC power source into a DC voltage. The reactor 10 boosts the DC voltage.

  For example, an inverter circuit is formed on the control board 9. The inverter circuit converts the DC voltage output by the converter circuit into an AC voltage. The inverter circuit supplies an AC voltage to the compressor and the blower motor 11 and the like. The inverter circuit changes the frequency of the AC voltage supplied to the compressor, the blower motor 11 and the like in multiple stages based on signals from the operation unit 2 and a temperature / humidity sensor (not shown), for example.

  As shown in FIG. 5, the reactor 10 and the blower motor 11 are attached to the front side of the structure in the housing 1. When viewed from the front side of the dehumidifier, a plurality of gaps 12 are formed between the blower motor 11 and the structure. The plurality of gaps 12 are formed, for example, at equal intervals along the peripheral edge of the circular blower motor 11 when viewed from the front side of the dehumidifier. The space on the front side in the housing 1 communicates with the space on the back side through the gap 12. That is, the space around the blower motor 11 communicates with the back side of the structure through the gap 12.

  FIG. 6 is a second enlarged view showing the internal structure of the dehumidifier in the first embodiment. FIG. 6 shows a normal state of the reactor 10 and the blower motor 11 as viewed from the front side of the dehumidifier.

  As shown in FIG. 6, the dehumidifier includes a reactor cover 13. The reactor cover 13 is formed in a box shape, for example. The reactor cover 13 is attached so as to cover the reactor 10. The reactor cover 13 covers the top, bottom, left, and right of the reactor 10 and the front surface. That is, the reactor 10 is disposed inside the reactor cover 13. The reactor cover 13 is made of, for example, a material having high waterproofness, fireproofing and heat dissipation properties. The reactor cover 13 is made of, for example, aluminum. Furthermore, heat dissipation may be promoted by attaching a heat transfer sheet to the reactor cover 13.

  As shown in FIG. 6, the dehumidifier includes a secondary air passage forming member 14. The auxiliary air passage forming member 14 is provided around the reactor 10 and the blower motor 11 and forms an “auxiliary air passage” described later. The auxiliary air passage forming member 14 includes a reactor peripheral portion 15 and a motor peripheral portion 16. The motor peripheral part 16 is located on the left side of the reactor peripheral part 15. The reactor peripheral part 15 and the motor peripheral part 16 are integrally formed, for example. The auxiliary air passage forming member 14 is formed of a material such as synthetic resin, for example.

  The reactor peripheral portion 15 is provided around the reactor cover 13 that covers the reactor 10. The reactor peripheral part 15 is formed in a box shape that is not sealed, for example. An opening is formed in the front surface of the reactor peripheral portion 15. The front surface of the reactor cover 13 is exposed from the opening. As described above, the reactor peripheral portion 15 which is a part of the auxiliary air passage forming member 14 is configured not to cover the front surface of the reactor cover 13. That is, the auxiliary air passage forming member 14 is configured not to cover a part of the reactor cover 13. For example, the opening is formed in the same size and the same shape as the front surface of the reactor cover 13. The reactor peripheral portion 15 covers the upper and lower surfaces of the reactor cover 13. A space is formed between the upper surface of the reactor peripheral portion 15 and the upper surface of the reactor cover 13. A space is formed between the lower surface of the reactor peripheral portion 15 and the lower surface of the reactor cover 13. That is, a space exists above and below the reactor cover 13 inside the reactor peripheral portion 15. The reactor peripheral part 15 is formed, for example, with an opening on the right side when viewed from the front side of the dehumidifier. That is, the space above and below the reactor cover 13 inside the reactor peripheral portion 15 communicates with the space on the right side of the reactor cover 13 as viewed from the front side of the dehumidifier.

  The motor peripheral part 16 is provided around the blower motor 11. For example, the motor peripheral portion 16 is formed in a circular shape when viewed from the front side of the dehumidifier. The motor peripheral portion 16 is formed in, for example, a hemispherical shape or a cylindrical shape. The motor peripheral part 16 is provided so as to cover the blower motor 11 from the front side. That is, the front side portion of the blower motor 11 is disposed inside the motor peripheral portion 16. The motor peripheral part 16 is located on the left side of the reactor peripheral part 15. The motor peripheral part 16 is continuous with the reactor peripheral part 15. The space inside the motor peripheral portion 16 communicates with the space above and below the reactor cover 13 inside the reactor peripheral portion 15. A substrate side opening 16 a is formed in the lower portion of the motor peripheral portion 16. That is, an opening is formed in the motor peripheral portion 16 at a portion adjacent to the power supply substrate 8. The space inside the motor peripheral portion 16 communicates with the space around the power supply substrate 8 via the substrate side opening 16a.

  FIG. 7 is a vertical sectional view of the dehumidifier in the first embodiment. FIG. 7 shows a cross section viewed from the right side of the dehumidifier.

  As shown in FIG. 7, the dehumidifier includes a condenser 6 a and an evaporator 6 b as the heat exchanger 6. The condenser 6a and the evaporator 6b are disposed above the compressor. The condenser 6a and the evaporator 6b are arranged side by side in the front-rear direction. The evaporator 6b is arrange | positioned rather than the condenser 6a at the back side. In addition, the dehumidifier includes a decompression device (not shown).

  The compressor, the condenser 6a, the pressure reducing device, and the evaporator 6b are sequentially connected by piping. The piping is filled with a refrigerant. The refrigerant circuit of the dehumidifier is constituted by the compressor, the condenser 6a, the pressure reducing device, and the evaporator 6b. The refrigerant circulates through the refrigerant circuit when the compressor is driven.

  The compressor compresses the refrigerant. The condenser 6a cools the refrigerant compressed by the compressor. The decompression device decompresses and expands the refrigerant cooled by the condenser 6a. The evaporator 6b performs heat absorption to the refrigerant decompressed and expanded by the decompression device.

  As shown in FIG. 7, a blower fan 17 is provided inside the housing 1. The blower fan 17 is disposed below the outlet 4. The blower fan 17 is disposed on the front side of the condenser 6a. The blower fan 17 is arranged with one side facing the direction in which the suction port 5 and the heat exchanger 6 are located. The other side of the blower fan 17 is attached to the blower motor 11.

  The blower fan 17 sucks air from one side directed to the suction port 5 and sends the air toward the upper blower outlet 4. That is, the blower fan 17 generates an air flow from the suction port 5 to the blower outlet 4. In FIG. 7, the flow of air from the inlet 5 to the outlet 4 is indicated by a dashed arrow.

  When the blower motor 11 is driven, the blower fan 17 rotates. When the blower fan 17 rotates, air is sucked into the housing 1 from the suction port 5. For example, indoor air in which the dehumidifier is installed is sucked into the housing 1 from the suction port 5. The air sucked from the suction port 5 passes through the evaporator 6b. Moisture contained in the air is removed by condensation in the evaporator 6b. The moisture condensed by the evaporator 6b is stored in a water storage tank (not shown). The dry air from which moisture has been removed by the evaporator 6b passes through the condenser 6a. The dry air that has passed through the condenser 6 a is sucked from one side of the blower fan 17. The dry air sucked from one side of the blower fan 17 is sent upward and discharged from the blower outlet 4 to the outside of the housing 1.

  As described above, a “main air passage” is formed in the housing 1 from the suction port 5 to the outlet 4 through the evaporator 6 b, the condenser 6 a and the blower fan 17. In the “main air passage”, the evaporator 6b is disposed upstream of the condenser 6a. The air passing through the “main air passage” is dehumidified by removing moisture by the evaporator 6b.

  The rotating blower fan 17 sucks air from the other side attached to the blower motor 11 and sends the air toward the upper outlet 4. That is, the blower fan 17 generates an air flow that passes through the periphery of the blower motor 11, passes through the gap 12, and reaches the outlet 4. This air flow is, for example, generated secondarily with the air flow in the “main air passage”. In FIG. 7, the flow of air passing through the periphery of the blower motor 11 and reaching the outlet 4 is indicated by solid arrows.

  FIG. 8 is a second front view showing the internal structure of the dehumidifier in the first embodiment. FIG. 8 shows the front surface of the dehumidifier with the housing 1 removed. FIG. 8 shows a state where the auxiliary air passage forming member 14 is attached around the reactor 10 and the blower motor 11. In FIG. 8, the flow of air passing through the periphery of the blower motor 11 and reaching the outlet 4 is indicated by solid arrows.

  As shown in FIG. 8, when air flows to the outlet 4 through the periphery of the blower motor 11, the air above and below the reactor cover 13 inside the reactor peripheral portion 15 is sucked into the motor peripheral portion 16. It is. Further, as shown in FIGS. 7 and 8, the air around the power supply substrate 8 is sucked into the motor peripheral portion 16 through the substrate-side opening 16a. The air on the right side of the reactor cover 13 is sucked into the space above and below the reactor cover 13 inside the reactor peripheral portion 15. In the space on the right side of the reactor cover 13, for example, a part of the air sucked into the housing 1 from the suction port 5 moves so as to go around from the back side of the dehumidifier.

  In this manner, inside the housing 1, from the right side of the reactor cover 13, the air outlet 4 passes through the inside of the reactor peripheral portion 15, the inside of the motor peripheral portion 16, the periphery of the blower motor 11, the gap 12, and the blower fan 17. A “sub-airway” leading to is formed. That is, the reactor 10 is provided in the “sub-air passage”. The reactor 10 is disposed upstream of the blower motor 11 in the “sub-air passage”. The air volume in the “sub wind path” is smaller than the air volume in the “main wind path”.

  A “main air passage” extending from the suction port 5 to the air outlet 4 and a “sub air passage” reaching the air outlet 4 through the periphery of the blower motor 11 are formed inside the housing 1 in the first embodiment. . The reactor 10 is not provided in the “main air passage”, but is provided in the “sub air passage”. For this reason, the reactor 10 is cooled by the air passing through the “sub-air passage”. As a result, in the dehumidifier, the reactor 10 can be cooled without hindering the blowing of air to the “main air passage” by the blower fan 17.

  In the first embodiment, the dehumidifier is provided around the blower motor 11 and the reactor 10 and includes a sub air passage forming member 14 that forms a “sub air passage”. The blower motor 11 is arranged in the housing 1 so that a gap 12 is formed from the space inside the auxiliary air passage forming member 14 to the other side of the blower fan 17. For this reason, on the front side of the dehumidifier, the air flow toward the gap 12 is concentrated by the auxiliary air passage forming member 14. Thereby, air flows intensively around the reactor 10. As a result, in the dehumidifier, the reactor 10 can be efficiently cooled without hindering the blowing by the blower fan 17.

  In the first embodiment, the dehumidifier includes a reactor cover 13 that is provided in the “sub-air passage” and covers the reactor 10. For this reason, the reactor 10 is protected from water wetting and ignition by the reactor cover 13. The auxiliary air passage forming member 14 does not cover a part of the reactor cover 13. For this reason, the heat released from the reactor 10 is released to the outside of the reactor cover 13 through a portion of the surface of the reactor cover 13 that is not covered by the auxiliary air passage forming member 14. As a result, in the dehumidifier, the reactor 10 can be efficiently cooled while being protected.

  In the first embodiment, the dehumidifier includes a power supply substrate 8 to which an AC power supply line 7 connected to an AC power supply is connected. The reactor 10 is disposed adjacent to the blower motor 11. The power supply board 8 is disposed adjacent to both the blower motor 11 and the reactor 10. For this reason, it can suppress that the wiring from the power supply board | substrate 8 to the reactor 10 becomes complicated. The reactor peripheral portion 15 of the auxiliary air passage forming member 14 has a substrate side opening 16 a formed in a portion adjacent to the power supply substrate 8. For this reason, an air flow toward the substrate side opening 16 a is generated around the power supply substrate 8. As a result, in the dehumidifier, not only the reactor 10 but also the power supply substrate 8 can be cooled.

  In this invention, the suction inlet 5 should just be formed in the surface which is neither the upper surface of the housing | casing 1, nor a lower surface. The suction port 5 may be formed on, for example, the left or right side surface of the housing 1. Even in this case, a “main air passage” can be formed if the blower fan 17 is arranged with one side facing the direction of the suction port 5 and the heat exchanger 6.

  In the present invention, the positional relationship in the left-right direction of the power supply board 8, the control board 9, the blower motor 11, and the reactor 10 may be opposite to that described in the first embodiment. That is, even when the control board 9 is arranged on the right side of the power supply board 8 as viewed from the front side of the dehumidifier, the blower motor 11 is arranged on the left side of the control board 9, and the reactor 10 is arranged on the left side of the blower motor 11. Good. Even in this case, if the auxiliary air passage forming member 14 is attached in such a direction that the motor peripheral portion 16 is positioned on the right side of the reactor peripheral portion 15, the “sub air passage” can be formed.

  In the present invention, the reactor peripheral portion 15 and the motor peripheral portion 16 may be formed separately. Even in this case, if the reactor peripheral portion 15 and the motor peripheral portion 16 are connected without a gap, a “sub-air passage” can be formed.
