NZ 753166 B2 [DESCRIPTION] [Title] DEHUMIDIFIER [Technical Field] The present invention relates to a dehumidifier.

[Background Art] PTL 1 discloses a dehumidifier. The dehumidifier includes an evaporator, a condenser, and a compressor. The dehumidifier disclosed in PTL 1 uses a refrigeration cycle including the evaporator, the condenser, and the compressor.

An EF value indicates energy efficiency of the dehumidifier. The EF value indicates a dehumidification amount per 1 kWh. To increase the EF value of the dehumidifier, it is necessary to reduce power consumption of the dehumidifier without changing the dehumidification amount of the dehumidifier. The power consumption of the dehumidifier using the refrigeration cycle is reduced by reduction of a load on the compressor. As a method of reducing the load on the compressor, there is a method of cooling the condenser by a larger amount of air. As an example of the method, PTL 1 discloses the dehumidifier including a dehumidification air duct to dehumidify the air and a heat dissipation air duct to cool the condenser.

[Citation List] [Patent Literature] [PTL 1] JP H5-87417 A [Summary] [Technical Problem] In the above-described PTL 1, the dehumidification air duct and the heat dissipation air duct are provided independently of each other. An air blower is disposed in each of the dehumidification air duct and the heat dissipation air duct. Accordingly, it is difficult to downsize a main body of the dehumidifier disclosed in the above- described PTL 1. Further, the above-described PTL 1 does not disclose a configuration for optimizing an air volume of the dehumidification air duct and an air volume of the heat dissipation air duct. The above-described PTL 1 does not consider improvement of the energy efficiency of the dehumidifier.

The present invention has been made to solve the above-described issues. An object of the present invention is to provide a more compact dehumidifier with higher energy efficiency.

[Solution to Problem] A dehumidifier according to the present invention includes an evaporator configured to allow a heat medium to flow through, a compressor configured to compress the heat medium passed through the evaporator, a second condenser configured to allow the heat medium compressed by the compressor to pass through, a first condenser configured to allow the heat medium passed through the second condenser to pass through, a housing, and a fan. The housing contains the evaporator, the compressor, the first condenser, and the second condenser. The fan is configured to take air into the housing and to feed the taken air to outside of the housing. The evaporator, the first condenser, and the second condenser are arranged in order in one side direction. The first condenser and the second condenser have a first space therebetween. The evaporator and the first condenser have a second space therebetween. The air taken into the housing by the fan is partially fed to the first space through the evaporator and the first condenser in order. Further, the air taken into the housing by the fan is partially fed to the first space without through the evaporator and the first condenser. The first space has a width in the one side direction larger than a width of the second space in the one side direction.

[Advantageous Effects of Invention] The present invention makes it possible to provide the more compact dehumidifier with higher energy efficiency.

In other words, the width L1 of the first space 101 is a dimension of the first space 101 in the one side direction. The width L2 of the second space 102 is a dimension of the second space 102 in the one side direction.

Note that the width L1 of the first space 101 is also simply referred to as the width L1. In addition, the width L1 is also referred to as the width of the first space 101 in the one side direction. Moreover, the width L2 of the second space 102 is also simply referred to as the width L2. The width L2 is also referred to as the width of the second space 102 in the one side direction.

As described above, the first condenser 33a and the second condenser 33b have the gap having the preset dimension therebetween. The gap is the first space 101.

In the present embodiment, the width L1 is a distance from the front surface of the first condenser 33a to the rear surface of the second condenser 33b. The first condenser 33a and the second condenser 33b are separated from each other by the width L1 that is an example of the preset first fixed length. In other words, the distance from the end surface of the first condenser 33a in the one side direction to the end surface of the second condenser 33b in the other side direction is the width L1 that is an example of the preset first fixed length.

Moreover, in the present embodiment, the width L2 is a distance from the front surface of the evaporator 31 to the rear surface of the first condenser 33a. The front surface of the evaporator 31 and the rear surface of the first condenser 33a are separated from each other by the width L2 that is an example of the second fixed length. In other words, the distance from the end surface of the evaporator 31 in the one side direction to the end surface of the first condenser 33a in the other side direction is the width L2 that is an example of the preset second fixed length.

Next, a dimension of the third space 103 is described. In the present embodiment, a width L3 of the third space 103 is larger than the width L1 of the first space 101. The width L3 of the third space 103 is a dimension of the third space 103 in the front-rear direction. In other words, the width L3 of the third space 103 is a dimension of the third space 103 in the one side direction. The width L3 of the third space 103 is also simply referred to as the width L3. In addition, the width L3 is also referred to as the width of the third space 103 in the one side direction.

As described above, the bell-mouth 35 and the second condenser 33b have the gap having the preset dimension therebetween. The gap is the third space 103. Further, the preset dimension is the width L3. The width L3 is an example of a preset third fixed length.

In the present embodiment, the width L3 is a distance from the front surface of the second condenser 33b to the rear end of the bell-mouth 35. The second condenser 33b and the bell-mouth 35 are separated from each other by the width L3 that is an example of the preset third fixed length. In other words, the distance from the end surface of the second condenser 33b in the one side direction to the end part of the bell-mouth 35 in the other side direction is the width L3 that is an example of the preset third fixed length.

As described above, in the present embodiment, the width L1 is larger than the width L2. Accordingly, the first space 101 is made larger than the second space 102.

In addition, the width L3 is larger than the width L1. Accordingly, the third space 103 is made larger than the first space 101. The width L1 is, for example, 10 [mm]. The width L2 is, for example, 3 [mm]. The width L3 is, for example, 15 [mm].

Further, as described above, the air duct leading from the suction port 11 to the blowout port 12 is provided inside the case 10. The air duct leading from the suction port 11 to the blowout port 12 includes a first air duct and a second air duct. In other words, the first air duct and the second air duct are provided inside the case 10.

The first air duct is provided to cause a part of the air taken into the case 10 by the fan 21 to be fed to the first space 101 through the evaporator 31 and the first condenser 33a in this order. The first air duct is provided also to cause a part of the air taken into the case 10 by the fan 21 to pass through the evaporator 31, the first condenser 33a, and the second condenser 33b in this order.

Further, the second air duct is provided to cause a part of the air taken into the case 10 by the fan 21 to be fed to the first space 101 without through the evaporator 31 and the first condenser 33a. The second air duct is provided also to cause a part of the air taken into the case 10 by the fan 21 to pass through the second condenser 33b without through the evaporator 31 and the first condenser 33a.

A dehumidification air duct 42 as an example of the first air duct is provided inside the case 10 according to the present embodiment. Further, a bypass air duct 43 as an example of the second air duct is provided inside the case 10. As illustrated in Fig. 11, each of the dehumidification air duct 42 and the bypass air duct 43 is an air duct leading from the suction port 11 to the first space 101.

The dehumidification air duct 42 is provided to cause a part of the air taken into the case 10 by the fan 21 to pass through the evaporator 31, the first condenser 33a, and the second condenser 33b in this order. The evaporator 31 and the first condenser 33a are disposed in the dehumidification air duct 42. The dehumidification air duct 42 leads from the suction port 11 to the first space 101 through the evaporator 31 and the first condenser 33a.

The bypass air duct 43 is provided to cause a part of the air taken into the case 10 by the fan 21 to pass through the second condenser 33b by bypassing the evaporator 31 and the first condenser 33a. The bypass air duct 43 is provided to cause air outside the dehumidifier 1 to directly pass through the second condenser 33b without through the evaporator 31 and the first condenser 33a. The bypass air duct 43 leads from the suction port 11 to the first space 101 by bypassing the evaporator 31 and the first condenser 33a.

The dehumidification air duct 42 and the bypass air duct 43 can be formed by an optional method. As an example, a partition member 17 is provided inside the case 10.

The partition member 17 is disposed inside the air duct leading from the suction port 11 to the blowout port 12. The partition member 17 partitions the dehumidification air duct 42 and the bypass air duct 43. The partition member 17 is, for example, a plate member.

In the present embodiment, as illustrated in Fig. 11, the planar partition member 17 is provided above the evaporator 31 and the first condenser 33a. The planar partition member 17 is disposed in parallel to the horizontal direction as an example. A part of the dehumidification air duct 42 is provided below the partition member 17. Further, the bypass air duct 43 is provided above the partition member 17. In the present embodiment, the bypass air duct 43 is provided above the evaporator 31 and the first condenser 33a.

As illustrated in Fig. 11, the bypass air duct 43 provided above the evaporator 31 and the first condenser 33a is located above an upper end of the suction port 11. Note that positional relationship between the suction port 11 and the bypass air duct 43 is not limited to the positional relationship according to the present embodiment. For example, the suction port 11 may be provided such that the upper end of the suction port 11 is located above the bypass air duct 43.

Further, as illustrated in Fig. 11, a vertical dimension of the second condenser 33b according to the present embodiment is larger than a vertical dimension of the evaporator 31 and a vertical dimension of the first condenser 33a. The vertical dimension of the second condenser 33b is, for example, 294 [mm]. The vertical dimension of the evaporator 31 is, for example, 252 [mm]. The vertical dimension of the first condenser 33a is, for example, 252 [mm].

As illustrated in Fig. 11, an upper end of the second condenser 33b according to the present embodiment is located above an upper end of the evaporator 31 and an upper end of the first condenser 33a. Further, the upper end of the second condenser 33b is located above the suction port 11. The upper end of the evaporator 31 and the upper end of the first condenser 33a are aligned in height. Further, a lower end of the evaporator 31, a lower end of the first condenser 33a, and a lower end of the second condenser 33b are aligned in height.

A diameter of the fan 21 is, for example, 252 [mm]. A height of the center axis of the fan 21 and a height of the center axis line F coaxial with the center axis are the same as a height of a vertical center of the evaporator 31 in the present embodiment.

Further, the height of the center axis of the fan 21 and the height of the center axis line F are lower than a vertical center of the second condenser 33b in the present embodiment.

Here, a projection surface orthogonal to the front-rear direction, namely, to the one side direction is referred to as a virtual projection surface. The fan 21, the evaporator 31, and the second condenser 33b are disposed such that the center axis of the fan 21 is closer to the center of the evaporator 31 than the center of the second condenser 33b in the above-described virtual projection surface. In other words, an intersection of the center axis line F and the virtual projection surface is closer to the center of the evaporator 31 than the center of the second condenser 33b in the virtual projection surface. Note that the height of the center axis line F may be different from the height of the center of the evaporator 31.

A lateral dimension of the evaporator 31 is, for example, 270 [mm]. A lateral dimension of the first condenser 33a is, for example, 270 [mm]. A lateral dimension of the second condenser 33b is, for example, 270 [mm]. As an example, the lateral dimension of the evaporator 31, the lateral dimension of the first condenser 33a, and the lateral dimension of the second condenser 33b are equal to each other. As described above, in the present embodiment, the vertical dimension of the second condenser 33b is larger than the vertical dimension of the evaporator 31 and the vertical dimension of the first condenser 33a. In the present embodiment, the second condenser 33b is larger than the evaporator 31 and the first condenser 33a in the projection surface orthogonal to the one side direction. Further, in the projection surface orthogonal to the one side direction, the evaporator 31 has the size same as the size of the first condenser 33a.

A left end of the evaporator 31, a left end of the first condenser 33a, and a left end of the second condenser 33b are aligned in position in the lateral direction as illustrated in Fig. 12. Further, a right end of the evaporator 31, a right end of the first condenser 33a, and a right end of the second condenser 33b are aligned in position in the lateral direction.

A lateral center of the evaporator 31, a lateral center of the first condenser 33a, and a lateral center of the second condenser 33b are aligned in position in the lateral direction.

In the present embodiment, as illustrated in Fig. 12, the center axis line F is shifted from the lateral center of the evaporator 31. In a case where the fan 21 is a sirocco fan, the fan 21 is contained in a spiral scroll casing. A shape of the spiral scroll casing is laterally asymmetrical about the center axis line F of the fan 21. In the present embodiment, the center axis line F is shifted from the lateral center of the evaporator 31, which reduces the space in which the fan 21 and the scroll casing are contained. In the present embodiment, the dehumidifier 1 is further downsized.

Further, a front-rear dimension of the evaporator 31 is, for example, 38 [mm]. A front-rear dimension of the first condenser 33a is, for example, 25 [mm]. A front-rear dimension of the second condenser 33b is, for example, 25 [mm]. Each of the above- described front-rear dimensions are a thickness of the planar evaporator 31, a thickness of the planar first condenser 33a, and a thickness of the planar second condenser 33b. As an example, the thickness of the first condenser 33a and the thickness of the second condenser 33b are equal to each other. Further, as an example, the thickness of the evaporator 31 is larger than the thickness of each of the first condenser 33a and the second condenser 33b. Moreover, the front-rear dimension of the fan 21 is, for example, 60 [mm]. As an example, the width L3 of the third space 103 is one-fourth of the front- rear dimension of the fan 21.

Note that the dimension of the evaporator 31, the dimension of the first condenser 33a, and the dimension of the second condenser 33b are not limited to those in the present embodiment. Further, the arrangement of the evaporator 31, the first condenser 33a, and the second condenser 33b is similarly not limited to that in the present embodiment.

Next, air flow during operation of the dehumidifier 1 according to the present embodiment is described. An arrow in Fig. 11 indicates the air flow during the operation of the dehumidifier 1.

The dehumidifier 1 starts operation, for example, when the operation unit 16a is operated by the user. First, the fan 21 is rotated. When the fan 21 is rotated, air flow directed from the suction port 11 to the blowout port 12 is generated inside the case 10.

As a result, the air outside the case 10 is taken into the case 10 through the suction port 11. The air outside the case 10 flows toward the inside of the case 10 through the suction port 11. The air outside the case 10 flows in the one side direction.

The air taken into the case 10 is distributed to the dehumidification air duct 42 and the bypass air duct 43. A part of the air taken into the case 10 is guided to the dehumidification air duct 42. In addition, a part of the air taken into the case 10 is guided to the bypass air duct 43.

The air guided to the dehumidification air duct 42 passes through the evaporator 31. Heat exchange is performed between the air passing through the evaporator 31 and the heat medium flowing through the evaporator 31. As described above, the heat medium decompressed by the decompression device 34 flows through the evaporator 31.

The heat medium at temperature lower than temperature of the air taken into the case 10 flows through the evaporator 31. The heat medium flowing through the evaporator 31 absorbs heat from the air passing through the evaporator 31.

As described above, the heat of the air passing through the evaporator 31 is absorbed by the heat medium flowing through the evaporator 31. In other words, the air passing through the evaporator 31 is cooled by the heat medium flowing through the evaporator 31. As a result, moisture contained in the air passing through the evaporator 31 is condensed. In other words, dew condensation occurs. The condensed moisture in the air is removed as liquid water from the air. The removed water is stored in, for example, a tank 18 provided inside the case 10.

Note that the tank 18 may be detachable from the case 10. Further, the case 10 may include a tank cover 10c. The tank cover 10c is a member covering the tank 18 inside the case 10. The tank cover 10c is provided integrally with the tank 18. The tank cover 10c and the tank 18 are integrally provided so as to be detachable from the front case 10a. Note that the tank cover 10c may not be provided integrally with the tank 18. The tank cover 10c may be provided so as to be detachable from the front case 10a, independently of the tank 18. The user can detach the tank 18 by removing the tank cover 10c from the front case 10a.

The air passed through the evaporator 31 is fed to the first condenser 33a through the second space 102. Heat exchange is performed between the air passing through the first condenser 33a and the heat medium flowing through the first condenser 33a. The heat medium flowing through the first condenser 33a is cooled by the air passing through the first condenser 33a.

The air passing through the first condenser 33a is heated by the heat medium flowing through the first condenser 33a. The air passed through the first condenser 33a reaches the first space 101. The air guided to the dehumidification air duct 42 is fed to the first space 101 through the evaporator 31, the second space 102, and the first condenser 33a in this order in the above-described manner. The air flows in the one side direction inside the dehumidification air duct 42.

As described above, the part of the air taken into the case 10 is guided to the bypass air duct 43. In the present embodiment, the bypass air duct 43 is located above the suction port 11. The flow of the air taken through the suction port 11 is bent upward after being directed to the one side direction. The air is guided to the bypass air duct 43 in the above-described manner. The air guided to the bypass air duct 43 is fed to the first space 101 without passing through the evaporator 31 and the first condenser 33a.

The air passed through the dehumidification air duct 42 and the air passed through the bypass air duct 43 are fed to the first space 101.

In the first space 101, the air passed through the dehumidification air duct 42 and the air passed through the bypass air duct 43 are mixed. The air mixed in the first space 101 passes through the second condenser 33b as illustrated in Fig. 11. Heat exchange is performed between the air passing through the second condenser 33b and the heat medium flowing through the second condenser 33b. The heat medium flowing through the second condenser 33b is cooled by the air passing through the second condenser 33b.

The air passing through the second condenser 33b is heated by the heat medium flowing through the second condenser 33b. The air passed through the second condenser 33b is dry as compared with the air outside the dehumidifier 1. The dry air passes through the fan 21. The air passed through the fan 21 is fed to a space above the case 10 from the blowout port 12. The dehumidifier 1 dehumidifies the air in the above- described manner. Further, the dehumidifier 1 supplies the dry air to the outside.

The dehumidifier 1 according to the above-described embodiment is configured such that a part of the air taken into the case 10 by one fan 21 passes through the evaporator 31, the first condenser 33a, and the second condenser 33b in this order.

Further, the dehumidifier 1 is configured such that a part of the air taken into the case 10 passes through the second condenser 33b without through the evaporator 31 and the first condenser 33a. The above-described embodiment makes it possible to increase the volume of the air passing through the second condenser 33b without increasing the volume of the air passing through the evaporator 31. Further, the above-described embodiment makes it possible to increase the volume of the air passing through the second condenser 33b without increasing the volume of the air passing through the first condenser 33a. According to the above-described embodiment, the second condenser 33b is efficiently cooled by the air passed through the bypass air duct 43, namely, by the air that has not been heated by the first condenser 33a. In addition, since the volume of the air passing through the evaporator 31 is not increased, the dehumidification amount by the evaporator 31 is maintained. According to the above-described embodiment, it is possible to provide the more compact dehumidifier 1 with the higher EF value.

Further, the first space 101 is provided inside the case 10. In the first space 101, the air passed through the dehumidification air duct 42 and the air passed through the bypass air duct 43 are mixed. The width L1 of the first space 101 is larger than the width L2 of the second space 102. Pressure loss of the first space 101 is reduced, and the air efficiently flows from the bypass air duct 43 to the first space 101. In addition, the first space 101 is made large, which causes the air to be mixed more uniformly inside the first space 101. According to the present embodiment, the second condenser 33b is efficiently cooled by the air mixed in the first space 101. As a result, the energy efficiency of the dehumidifier 1 is further improved.

Furthermore, the width L2 of the second space 102 is smaller than the width L1 of the first space 101. According to the present embodiment, it is possible to further downsize the dehumidifier 1 by minimizing the width L2 of the second space 102.

Note that the suction port 11 and the blowout port 12 may be provided at respective optional positions. For example, the suction port 11 and the blowout port 12 may be provided on a side surface of the case 10. Further, the evaporator 31, the first condenser 33a, and the second condenser 33b may be arranged in this order, for example, in the vertical direction. Furthermore, the bypass air duct 43 may be provided, for example, on the side of the evaporator 31 and the first condenser 33a.

As described above, the dehumidification air duct 42 and the bypass air duct 43 can be formed by an optional method. The partition member 17 may not be provided inside the case 10. The dehumidification air duct 42 and the bypass air duct 43 may be formed by a member other than the case 10 and the partition member 17.

Further, the dehumidification air duct 42 and the bypass air duct 43 may not be provided inside the case 10. It is sufficient to provide the air duct inside the case 10 such that a part of the air taken by the fan 21 is fed to the first space 101 without through the evaporator 31 and the first condenser 33a. For example, the case 10 may include an opening to take the air into the case 10, separately from the suction port 11. The opening is provided to cause the air taken in from the opening to be fed to the first space 101 without through the evaporator 31 and the first condenser 33a. For example, the opening is provided on the side surface of the case 10 between the first condenser 33a and the second condenser 33b at a position in the front-rear direction.

In the above-described embodiment, the third space 103 is provided between the second condenser 33b and the bell-mouth 35 inside the case 10. The width L3 of the third space 103 is larger than the width L1 of the first space 101. The third space is made large, which reduces pressure loss of the third space 103. This reduces the output of the fan 21 necessary to cause the constant volume of air to flow. According to the above-described embodiment, the energy efficiency of the dehumidifier 1 is further improved.

Note that the pressure loss of the third space 103 is reduced as the width L3 is larger until the width L3 reaches an upper limit. The upper limit is, for example, 40 [mm]. In addition, the upper limit is, for example, one-sixth of the diameter of the fan Further, when the width L3 of the third space is made large, the dimension of the dehumidifier 1 is also increased. Therefore, the width L3 of the third space may be equal to, for example, the width L1 of the first space 101. When the width L3 is larger than or equal to the width L1, the output of the fan 21 necessary to cause the constant volume of air to flow is more reduced. Moreover, the width L3 is made equal to the width L1, which makes it possible to further downsize the dehumidifier 1.

In addition, the center axis line F of the fan 21 according to the above-described embodiment is closer to the center of the evaporator 31 than the center of the second condenser 33b in the projection surface orthogonal to the one side direction. As a result, a larger amount of the air flows into the dehumidification air duct 42 as compared with the bypass air duct 43. According to the above-described embodiment, it is possible to provide the dehumidifier 1 that can sufficiently dehumidify the air. As an example, the volume of the air flowing through the dehumidification air duct 42 is preferably about twice the volume of the air flowing through the bypass air duct 43.

In the above-described embodiment, the center axis line F of the fan 21 is shifted from the lateral center of the evaporator 31. The center axis line F of the fan 21 and the lateral center of the evaporator 31 may be the same as each other in position in the lateral direction. Further, the center axis line F of the fan 21 may pass through the center of the evaporator 31 in the projection surface orthogonal to the one side direction. As a result, the larger amount of the air flows through the evaporator 31.

In the above-described embodiment, the second condenser 33b is larger than the evaporator 31 and the first condenser 33a in the projection surface orthogonal to the one side direction. Here, an area where the heat exchanger and the air passing through the heat exchanger come into contact with each other is referred to as a ventilation area.

According to the above-described embodiment, the ventilation area of the second condenser 33b can be made larger than the ventilation area of the evaporator 31 and the ventilation area of the first condenser 33a. As a result, the second condenser 33b is more effectively cooled.

Further, in the projection surface orthogonal to the one side direction, the evaporator 31 has the size same as the size of the first condenser 33a. This facilitates design of the dehumidifier 1 and design of the air duct inside the case 10. Moreover, this results in downsizing of the dehumidifier 1.

In the above-described embodiment, the lower end of the evaporator 31, the lower end of the first condenser 33a, and the lower end of the second condenser 33b are aligned in height. According to the above-described embodiment, design and manufacture of the dehumidifier 1 become easier. According to the above-described embodiment, it is possible to easily form the bypass air duct 43 inside the case 10. Further, the evaporator 31, the first condenser 33a, and the second condenser 33b as the heat exchangers are heavy loads occupying a relatively large part of the total weight of the dehumidifier 1.

The respective lower ends of the evaporator 31, the first condenser 33a, and the second condenser 33b as the heavy loads are aligned, which causes the dehumidifier 1 to stably stand by itself. Further, the user can carry the dehumidifier 1 in a stable state.

Note that the vertical dimension of the second condenser 33b may be equal to the vertical dimension of the first condenser 33a. This further reduces the weight of the dehumidifier 1. Moreover, this makes it possible to further downsize the dehumidifier 1.

Further, the lower end of the second condenser 33b may be located above the lower end of the evaporator 31 and the lower end of the first condenser 33a. In this case, even when the second condenser 33b has the size same as the size of the evaporator 31 and the size of the first condenser 33a, it is possible to form the bypass air duct 43 and the dehumidification air duct 42 above the evaporator 31 and the first condenser 33a.

In the above-described embodiment, both of the air passed through the dehumidification air duct 42 and the air passed through the bypass air duct 43 flow through the second condenser 33b. The inside of the case 10 may be configured such that the volume of the air passing through the second condenser 33b is larger than the volume of the air passing through the evaporator 31 and the first condenser 33a. For example, the inside of the case 10 may be configured such that the air passed through the dehumidification air duct 42 and the air passed through the bypass air duct 43 all passes through the second condenser 33b. Moreover, as described above, the opening through which the air is taken into the case 10 may be separately provided in the case 10, in addition to the suction port 11. The opening is provided, for example, such that the volume of the air passing through the second condenser 33b is larger than the volume of the air passing through the evaporator 31 and the first condenser 33a. The volume of the air passing through the second condenser 33b is increased, which causes the second condenser 33b to be more effectively cooled.

In the above-described embodiment, the bypass air duct 43 is positioned above the evaporator 31 and the first condenser 33a. The bypass air duct 43 positioned above the evaporator 31 and the first condenser 33a leads from the suction port 11 to the first space 101 without through, for example, a U-shaped joint pipe 36 attached to the respective side surfaces of the evaporator 31 and the first condenser 33a. In addition, the bypass air duct 43 positioned above the evaporator 31 and the first condenser 33a leads from the suction port 11 to the first space 101 without through the piping that connects the evaporator 31, the compressor 32, the first condenser 33a, the second condenser 33b, and the decompression device 34. An obstacle is eliminated from the bypass air duct 43, which reduces the pressure loss of the bypass air duct 43.

Moreover, a handle 14 may be contained at a position where the bypass air duct 43 is provided. The handle 14 is attached to the case 10. The handle 14 is a member held by the user when the user moves the dehumidifier 1. According to the above-described embodiment, it is possible to provide the handle 14 at a position near the evaporator 31 and the first condenser 33a that are the heavy loads. As a result, the user can move the dehumidifier 1 in a stable state by holding the handle 14.

[Industrial Applicability] The dehumidifier according to the present invention is used to, for example, dry an optional object.

[Claim 1] A dehumidifier, comprising: an evaporator configured to allow a heat medium to flow through; a compressor configured to compress the heat medium passed through the evaporator; a second condenser configured to allow the heat medium compressed by the compressor to pass through; a first condenser configured to allow the heat medium passed through the second condenser to pass through; a housing that contains the evaporator, the compressor, the first condenser, and the second condenser; a fan configured to take air into the housing and to feed the taken air to outside of the housing; the evaporator, the first condenser, and the second condenser being arranged in order in one side direction; the first condenser and the second condenser having a first space therebetween; the evaporator and the first condenser having a second space therebetween; the air taken into the housing by the fan being partially fed to the first space through the evaporator and the first condenser in order; the air taken into the housing by the fan being partially fed to the first space without passing through the evaporator and the first condenser; and the first space having a width in the one side direction larger than a width of the second space in the one side direction.

2. [Claim 2] The dehumidifier according to claim 1, further comprising a bell-mouth that is contained inside the housing and is disposed between the second condenser and the fan, wherein the fan and the bell-mouth are disposed in the one side direction with respect to the second condenser, the bell-mouth and the second condenser have a third space therebetween, and the third space has a width in the one side direction larger than or equal to the width of the first space in the one side direction.

3. [Claim 3] The dehumidifier according to claim 1 or 2, wherein the second condenser is larger than the evaporator and the first condenser in a projection surface orthogonal to the one side direction.

4. [Claim 4] The dehumidifier according to any one of claims 1 to 3, wherein the evaporator has a size same as a size of the first condenser in a projection surface orthogonal to the one side direction.

5. [Claim 5] The dehumidifier according to any one of claims 1 to 4, wherein a lower end of the evaporator, a lower end of the first condenser, and a lower end of the second condenser are aligned in height while the housing is placed on a horizontal surface.

6. [Claim 6] The dehumidifier according to any one of claims 1 to 4, wherein a lower end of the second condenser is located above a lower end of the evaporator and a lower end of the first condenser while the housing is placed on a horizontal surface.

7. [Claim 7] The dehumidifier according to any one of claims 1 to 6, wherein a volume of air passing through the second condenser by the fan is larger than a volume of air passing through the evaporator and the first condenser by the fan.
