Description

DEHUMIDIFIING DEVICE

The present invention relates to a dehumidifying device used in a residence space or the like.

A dehumidifying device has been put to practical use by reducing the humidity of the living space and increasing the comfort.

As an example of a conventional dehumidifying device, there is a dehumidifier having a main body case, a dehumidifying part provided in the main body case, and an air blower for blowing air outside the main body case, which is sucked from the air suction port, through the dehumidifying part to the outside of the main body case There is one thing.

The dehumidifying part is constituted by a refrigeration cycle in which a compressor, a radiator, an inflator and a heat absorber are successively connected in an annular shape. A part of the air sucked into the main body case from the air suction port by the blower is taken out to the outside of the main body case through the air suction port, the first passage of the heat exchanger, and the radiator. Further, another portion of the air sucked from the air inlet by the blower is taken out from the air outlet through the second passage of the heat exchanger and the heat radiator to the outside of the main body case (for example, Patent Document 1).

In the conventional dehumidifying device, a part of the air sucked into the main body case from the air suction port by the blower is cooled by the heat absorber to be condensed, and then the air is sucked from the air outlet to the outside of the main body case through the first passageway and the heat radiator Take out.

Further, in the conventional dehumidifier, another portion of the air sucked from the air inlet by the blower passes through the second passage of the heat exchanger, and is taken out from the air outlet through the radiator to the outside of the main body case.

That is, the indoor air passing through the second passage of the heat exchanger is cooled by the air flowing through the first passage of the heat exchanger from the heat absorber, and is tried to be condensed here.

However, the indoor air passing through the second passage of the heat exchanger has a problem that it is taken out from the air blow-out port to the outside of the main body case in a state of not sufficiently condensing.

That is, the air introduced into the first passage of the heat exchanger is air after condensation in the heat absorber. However, even if the heat is cooled by the heat absorber, the temperature is not as low as the heat absorber. Therefore, even if the air flowing into the second passage is cooled by the air introduced into the first passage, the air may not reach the air flowing into the second passage until condensation occurs. In this case, the air passing through the second passage was discharged to the room without performing dehumidification, so that the dehumidifying effect was lowered.

Microfilm simulating the specification originally attached to the application at the time of filing of Japanese utility model publication No. 56-20628

Thus, the present invention provides a dehumidifying device with enhanced dehumidifying effect.

A dehumidifying device according to one aspect of the present invention includes a main body case having an air inlet and an air outlet, and a dehumidifying portion for dehumidifying air in the main case by a refrigeration cycle in which a compressor, a radiator, an inflator and a heat absorber are sequentially connected . And a blower for blowing air outside the main body case, which is sucked from the air suction port, through the dehumidifying part, and then blowing the air from the air blowout port to the outside of the main body case. And a second passage independent of the first passage and the heat exchanger for exchanging heat between the air flowing through the first passage and the air flowing through the second passage. And a first dehumidifying path for taking out a part of the air sucked into the main body case from the air suction port by the blower through the first passage of the heat absorber, the heat exchanger, and the radiator to the outside of the main body case. And a second dehumidifying passage for blowing another portion of the air sucked into the main body case from the air intake port by the blower to the outside of the main body case through the second passageway of the heat exchanger and the radiator. Further, the amount of air flowing through the second passage of the heat exchanger is made smaller than the amount of air flowing through the first passage of the heat exchanger.

As described above, the air flowing through the first passage of the heat exchanger can sufficiently condense the air flowing through the second passage. That is, it is possible to cause condensation even in the heat exchanger portion, so that the dehumidifying effect as a whole can be enhanced.

The following embodiments are illustrative of the present invention, and do not limit the technical scope of the present invention. Throughout the drawings, the same components are denoted by the same reference numerals, and a description thereof will be omitted. Further, in the drawings, the details of the respective parts which are not directly related to the present invention are not described.

(First Embodiment)

As shown in Fig. 1, the dehumidifying device 50 according to the present embodiment has a box-shaped main body case 1 as an outer periphery. The main body case 1 is provided outside the main body case 1, (1) interior is distinguished. An air inlet port 2 is provided at an upper portion and an air inlet port 3 is disposed at a lower portion of the air inlet port 2 on the back side of the main body case 1. [ In the main body case 1, an air blow-out port 4 is arranged on the front side facing the back surface. On the top of the main body case 1, an operation portion 25 is arranged.

The air inlet port (2) and the air inlet port (3) are provided in a rectangular plane that sucks air from a direction perpendicular to the back surface.

A louver 31 for changing the direction of air taken out from the air blow-out port 4 is provided above the air blow-out port 4.

The operation unit 25 receives input from a user, for example, or displays information on a dehumidifying device such as an operation mode or a current humidity to the user.

2, an air passage 34, a blower 6, and a dehumidifying part 5 are provided in the main body case 1 of the dehumidifying device 50. [

The air passage 34 communicates the air inlet 2 and the air inlet 3 with the air outlet 4. In this embodiment, the air passage 34 is composed of two dehumidifying paths, that is, a first dehumidifying path and a second dehumidifying path, but the details will be described later.

The blower 6 is provided with a motor 32 and a fan 33 connected to the rotating shaft of the motor 32 and sucking and exhausting air. The blower 6 blows air outside the main body case 1 sucked from the air suction port 2 and the air suction port 3 from the air blow-out port 4 to the main body case 1 after passing through the dehumidifying part 5. [ Take it out. This air passage is an air passage (34).

The dehumidifying part 5 is constituted by a refrigeration cycle in which the compressor 7, the radiator 8, the inflator 9 and the heat absorber 10 are annularly connected in this order. In the refrigeration cycle, for example, an alternative refrigerant (HFC134a) is used as the refrigerant.

In the main body case 1, a heat absorber 10 is provided on the air inlet port 2 and the air inlet port 3 side (on the upstream side in the direction of air flow) of the air passage 34. A radiator 8 is provided on the side of the air outlet port 4 (on the downstream side in the air flow direction) of the air passage 34.

A space is provided between the heat absorber (10) and the radiator (8), and a sensible heat exchanger (11) is disposed in this space.

That is, in the main body case 1, the air intake port 2 and the air intake port 3 of the air passage 34 communicating with the air outlet port 4 from the air intake port 3 are provided on the side of the air intake port 2 and the air intake port 3, A heat absorber 10 is provided and then a heat exchanger 11 is provided and then a radiator 8 is provided.

A funnel-shaped collecting portion 12a is provided below the heat absorber 10 and the heat exchanger 11 in the main body case 1. [ A collecting tank 12b is disposed below the collecting portion 12a so as to be detachable from the main body case 1.

That is, the dehumidifying device 50 has a configuration in which condensation is generated in the heat absorber 10 and the heat exchanger 11, condensed water generated by the condensation is collected in the collecting portion 12a and introduced into the collecting tank 12b .

Next, the detailed structure of the heat exchanger 11 will be described with reference to Fig. As shown in Fig. 3, the heat exchanger 11 is constituted by alternately polymerizing a plurality of alternately arranged plate bodies 13 made of synthetic resin and a synthetic resin sheet 14 forming a transverse air passage.

A plurality of ribs 15 extending in the longitudinal direction are formed integrally with the plate body 13 at a predetermined interval on the surface of the plate body 13 made of a synthetic resin for forming an end airway. One surface of the rib 15 is brought into close contact with the rear surface of the adjacent plate member 14 so that the end surface of the plate member 13 and the rear air passage 13a, .

Similarly, a plurality of transversely extending ribs 16 are formed integrally with the plate body 14 at a predetermined interval on the surface of the plate member 14 made of a synthetic resin for forming the transverse air passage. One surface of the rib 16 is brought into close contact with the rear surface of the adjacent plate member 13 so that the surface of the plate member 14, the rib 16, and the back surface of the plate member 13, .

The air passage spaces of the end air passage 13a and the side air passage 14a are independent of each other, that is, there is no passage of air.

The heat exchanger 11 thus configured has a rectangular parallelepiped shape. However, the term "rectangular parallelepiped shape" as used herein does not necessarily mean that all surfaces are strictly rectangular, and that all adjacent surfaces need not intersect at right angles. That is, the shape of the rectangular parallelepiped may be a hexahedron at a glance.

In the heat exchanger (11), an opening (17) for a first passage is formed in a rectangular parallelepiped facing long side. Further, in the heat exchanger 11, the openings 18 for the second passage are formed in the opposite short sides of the rectangular parallelepiped. That is, the second passage is longer than the first passage.

The opening 17 constitutes the upstream side opening 17a on the side of the heat absorber 10 and the downstream side opening 17b constitutes the side of the radiator 8 side.

The opening 18 constitutes an upstream opening 18a on the air intake port 2 side and the downstream opening 18b on the side of the collector 12a (vertically downward direction).

Next, the operation of the dehumidifier will be described with reference to Fig.

The air X is sucked into the main body case 1 from the air suction port 3 by driving the blower 6. [ The air X flows through the heat absorber 10, the upstream side opening 17a of the heat exchanger 11, the first passage on the lateral side, the downstream side opening 17b, the radiator 8 and the blower 6, (4) to the outside of the main body case (1). The path of the air (X) is the above-described first dehumidification path. The air X can be defined as the air sucked from the air intake port 2 and the air intake port 3 of the air intake port 3, that is, a part of the sucked air.

The air X flowing through this path is first cooled by the heat absorber 10, and condensation is generated. As shown in Fig. 2, the condensation water generated by the occurrence of condensation drops downward and collects in the funnel-shaped collecting portion 12a and flows into the collecting tank 12b.

Further, since the dried air (X) after condensation has been taken out is taken out from the main body case (1) through the air blow-out port (4), for example, the humidity in the room can be lowered.

On the other hand, by driving the blower 6, air (Y) is sucked into the main body case (1) from the air suction port (2). The air Y passes from the upstream side opening 18a of the heat exchanger 11 through the second passage on the downstream side and passes through the downstream side opening 18b, the radiator 8, the air blower 6, To the outside of the main body case 1. The path of the air (Y) is the above-described second dehumidification path. The air Y can be defined as the air sucked from the air intake port 2 of the air intake port 2 and the air intake port 3, that is, another portion of the sucked air. In the present embodiment, the total amount of air sucked into the dehumidifier 50 is obtained by adding a portion of the air and two other portions of the air.

3, the first passage (the passage of the air X) and the second passage (the passage of the air Y) of the heat exchanger 11 cross each other. Therefore, the air (air (X) flowing through the first passage and the air (air (Y) flowing through the second passage) can be heat-exchanged.

Here, air (X) flowing through the first passage in the transverse direction of the heat exchanger (11) is cooled by passing through the heat absorber (10) as described above. Therefore, the heat exchanger 11 can lower the temperature of the air (Y) flowing through the second passage that has not passed through the heat absorber (10) by heat exchange. This point is positively utilized to cause condensation to occur on the air (Y) flowing through the second passage by the heat exchanger (11).

In order to generate condensation, the amount of air (Y) flowing through the second passage of the heat exchanger (11) is made smaller than the amount of air (X) flowing through the first passage of the heat exchanger (11) .

Specifically, the heat exchanger 11 made the ventilation resistance of the second passage (the passage of the air Y) larger than the ventilation resistance of the first passage (the passage of the air X).

That is, in the present embodiment, as shown in FIG. 2, the heat exchanger 11 has a rectangular parallelepiped shape. As shown in Fig. 3, the opening 17 for the first passage is formed at the opposite long side, and the opening 18 for the second passage is formed at the opposite short side. The air flow of the air to the blower 6 is made to be the view point and the air resistance of the second passage is made to be larger than the opening area of the short side of the opening 18 by making the opening area of the long side opening 17 larger than the opening area of the short side opening 18. [ Air resistance.

Since the ventilation resistance of the second passage (air passage Y) of the heat exchanger 11 is made larger than the ventilation resistance of the first passage (air passage X) in this manner, the air flowing through the second passage (Y) is smaller than air (X) flowing through the first passage.

Therefore, the cooled air (X) flowing through the first passage sufficiently cools the air (Y) which is smaller than the air (X) flowing through the second passage, and can cause condensation.

As a result, as shown in Fig. 2, condensation water is also generated from the air (Y) flowing through the second passage. The dew condensation water drops downward from the second passage, is collected in the funnel-shaped collecting portion 12a, and flows into the collecting tank 12b.

The dried air Y after the dew condensation is generated passes through the opening 18b on the downstream side of the heat exchanger 11, the radiator 8 and the blower 6 and flows from the air outlet 4 to the outside of the main body case 1 . Thus, for example, the humidity of the room can be lowered.

2, the opening 18b on the downstream side of the heat exchanger 11 has an inclined surface inclined toward the radiator 8 side.

That is, the downstream side opening portion 18b is inclined toward the next radiator 8 side so that the air Y flows smoothly toward the radiator 8 side.

Further, the inclined surface guides the dew condensed water generated in the second passage to the distal end portion 54 further downward from the downstream-side opening portion 18b. The number of condensation led to the leading end portion 54 is increased with the number of other condensation condensation. Thereby, the dropping of the condensation water is promoted to improve the drainage of water, so that the water drops can stay and the air resistance can be prevented.

In this embodiment, the flow rate ratio of air (X) to air (Y) is set to 26 to 18 by employing the above configuration.

That is, the amount of air flowing through the second passage (air passage Y) of the heat exchanger 11 is reduced to be smaller than the amount of air flowing through the first passage (passage X of the air X) of the heat exchanger 11. Thus, even if the temperature of the air flowing through the first passage (the passage of the air X) of the heat exchanger 11 is somewhat higher than the temperature of the heat absorber 10, the second passage (the passage of the air B) The flowing air can be sufficiently condensed. As a result, it is possible to cause condensation even in the heat exchanger (11) portion, thereby enhancing the dehumidifying effect as a whole.

Further, the opening 17 for the first passage is provided at the opposite long side, so that the passage length of the second passage is made longer than the passage length of the first passage. As a result, the cooling time for cooling the air (Y) flowing through the second passage by the air (X) becomes longer, and the dehumidification efficiency can be increased.

(Second Embodiment)

Next, the dehumidifying device according to the second embodiment will be described with reference to Figs. 4, 5, 6, and 7. Fig.

The dehumidifying device 51 according to the present embodiment is characterized in that the dehumidifying device 50 according to the first embodiment is provided with an air flow rate adjusting section for increasing or decreasing the amount of air flowing through the second passage of the heat exchanger 11 .

Specifically, as shown in Fig. 4, the air flow rate regulating section is constituted by an opening / closing section 19 for opening / closing the second passage of the heat exchanger 11 and a driving section 20 for driving the opening / do.

The opening and closing part 19 is a flat plate having an area including the upstream side opening 18a disposed between the air inlet 2 and the upstream side opening 18a in the second passage. The opening and closing part 19 is rotatably supported by the driving part 20 provided on the end side of the upstream opening 18a on the side opposite to the air inlet 2 as a rotation axis. By this rotation, the opening and closing part 19 opens and closes the upstream opening 18a of the heat exchanger 11, that is, the second passage.

The opening / closing portion 19 is located in a closed state to cover the upstream side opening portion 18a, that is, restricts the inflow of air into the heat exchanger 11. [ The opening and closing part 19 lifts the short side near the air inlet 2 in the open state with the driving part 20 as a rotation axis to allow the air to flow into the upstream side opening 18a .

The driving part 20 functions as a rotating shaft of the opening and closing part 19 and rotatably supports the opening and closing part 19 in the vicinity of the upper end of the radiator 8. [ The drive unit 20 corresponds to, for example, a motor and a gear rotationally driven by the motor.

The driving unit 20 is connected to the control unit 21 together with the blower 6 and the compressor 7 as shown in Fig.

The control unit 21 is also provided with a first temperature sensor 22 for detecting the temperature of air entering the air intake port 3 shown in Fig. 4, a second temperature sensor 22 for detecting the temperature of the heat absorber 10, A sensor 23, a memory 24, and an operation unit 25 are connected.

The operating section 25 is provided on the upper outer surface of the main body case 1 and allows the user to instruct the dehumidifying device 51 to change the operation mode or to select a function, And a display panel for displaying information on the display panel.

The control unit 21 is, for example, a microcomputer that controls the operation of the dehumidifier 51 by reading and executing an operation program from the memory 24 in which the operation program is stored. The control unit 21 receives a temperature signal from the first temperature sensor 22 or the second temperature sensor 23 and outputs a signal indicating the operation of the blower 6, the compressor 7, the drive unit 20, On-off, and the like. Details of each process executed by the control unit 21 will be described below.

Next, the processing of the control section 21 based on the temperature signal from each temperature sensor will be described.

When the temperature t1 of the air entering the air intake port 3 detected by the first temperature sensor 22 is higher than the first set temperature te (e.g., 18 deg. C) at the time of starting the dehumidifying apparatus 51 , The control unit 21 executes an operation indicated by " normal temperature " in Fig.

That is, the blower 6 and the compressor 7 are turned on, that is, the opening and closing part 19 is opened as shown in FIG. By the opening operation, the opening and closing part 19 opens the upstream side opening 18a, and the dehumidification operation described above is executed (step S1 of Fig. 7, step S2).

When the temperature t1 of the air entering the air intake port 3 detected by the first temperature sensor 22 is equal to or lower than the first set temperature te (e.g., 18 占 폚) Quot; low temperature ".

That is, the blower 6 and the compressor 7 are driven, and the opening and closing part 19 is closed by the driving part 20. By the closing operation, the opening and closing part 19 closes the upstream side opening part 18a, and the dehumidifying operation is performed in this state (step S2 in Fig. 7, step S3).

In this state, the air (X) sucked from the air suction port (3) by the blower (6) is first cooled by the heat absorber (10). The condensation water generated by the occurrence of condensation falls downward, is collected in the funnel-shaped catch portion 12a, and flows into the catchment tank 12b.

The air X after the condensation has been generated flows through the upstream opening 17a of the heat exchanger 11, the first passageway of the transverse direction, the downstream opening 17b, the radiator 8 and the blower 6 And is taken out from the main body case 1 through the air blow- Thus, for example, the humidity of the room can be lowered.

Incidentally, when the temperature is lower than the set temperature, that is, the low temperature state, the frosting phenomenon in which the frost adheres to the heat absorber 10 tends to occur easily. In this case, since the ventilation resistance of the heat absorber 10 is increased, the balance of the air resistance in the first passage and the air passage in the second passage is changed. That is, the air volume of the air X decreases and the air volume of the air Y increases. Further, as the amount of air in the heat absorber 10 is reduced, the implantation is further promoted. Therefore, in this low-temperature situation, the opening and closing part 19 is closed. That is, even when the blower 6 is driven, the air (Y) does not flow into the second passage of the heat exchanger 11 by closing the second dehumidifying path. By doing so, all of the suction force of the blower 6 can be used for suction of the first path, so that the amount of air passing through the heat absorber 10 can be increased. Thereby, even when the implantation is started, the air flowing in the heat absorber 10 is increased, that is, the promotion of the implantation is suppressed, and further, the dehumidification operation for excluding the implantation is continued.

In this state, when the initial operation time TS elapses, for example, 25 minutes (step S4 in Fig. 7), the second temperature sensor 23 (ts) for detecting the temperature of the heat absorber 10 part It is determined whether or not it is equal to or lower than the set temperature t0 (e.g., 0.5 DEG C). The initial operation time TS is a time from when the operation indicated by the above-mentioned " low temperature " is started.

When the temperature detected by the second temperature sensor 23 (ts) is equal to or lower than the second set temperature t0 (for example, 0.5 deg. C), the controller 21 controls the "de-ice" (Step S5 and step S6 in Fig. 7).

In this state, the conception is spread on the surface of the heat absorber 10 by continuing the operation in the low temperature state. Therefore, the controller 21 executes the de-icing operation to solve the conception.

The control unit 21 stops the compressor 7 and drives the blower 6 in a state in which the opening and closing unit 19 is closed (step S6 in Fig. 7).

The air blown into the heat absorber 10 is intensively blown by the air blower 6 to suck the air X sucked only from the air suction port 3 to thereby relieve the surface of the heat absorber 10. The operation time of the Dice operation is, for example, 10 minutes (Td: Dice integration time).

After elapse of the Dice integration time Td, the control unit 21 acquires the temperature of the second temperature sensor 23 (ts) for detecting the temperature of the heat absorber 10 portion. The control unit 21 determines whether or not the temperature detected by the second temperature sensor 23 (ts) is equal to or higher than the second set temperature t0 (e.g., 0.5 deg. C) (step S8, step S9) Or when the set time Td (for example, 10 minutes) elapses (step S7 in Fig. 7, step S9).

As described above, it is possible to suppress the promotion of the implantation and to perform the dehumidification operation while excluding the implantation, by merely adjusting the air amount in the air flow rate adjuster shown by the "low temperature" operation. In other words, even when the implantation occurs, the implantation can be excluded while continuing the dehumidification operation, so that the dehumidification can be efficiently performed.

(Third Embodiment)

Next, the dehumidifying device according to the third embodiment will be described with reference to Fig.

The dehumidifying device 52 according to the present embodiment is characterized in that the first dehumidifying path through which the air X flows in the configuration shown in the first embodiment and the second dehumidifying path through which the air Y flows And a third dehumidifying path through which the air (Z) flows, in addition to the second dehumidifying path. Further, the air (Z) is another part of the air sucked from the air inlet (2 or 3). In the present embodiment, the total amount of air sucked into the dehumidifying device 52 is obtained by adding a portion of the air, another portion of the air, and another portion of the air. In other words, another portion of the air may be a portion of the entire amount of air sucked into the dehumidifier 52, excluding a portion of the air and other portions of the air.

The other part of the air sucked from the air suction port 2 or the air suction port 3 by the blower 6 does not pass through the heat absorber 10 and the heat exchanger 11, (4) to the outside of the main body case (1) through the upper portion (8a) of the main body case (8).

A path taken out from the air outlet 4 through the radiator 8 to the outside of the main body case 1 through the path through which the air Z passes, that is, the heat absorber 10 and the heat exchanger 11, It is a dehumidifying path.

Here, the radiator 8 protrudes vertically upward from the upper end of the heat absorber 10 or the upper end of the heat exchanger 11. This protruding portion corresponds to the upper portion 8a and can be a part of the radiator 8 above the center in the height direction of the radiator 8. [ The vertical direction indicates the upper side in the case where the dehumidifying device 52 is installed in a state in which the dehumidifier 52 can be normally operated.

In the present embodiment, the air Z passes through the upper portion 8a of the radiator 8. The air X and the air Y pass through the other part of the radiator 8 below the upper part 8a of the radiator 8 through which the air Z passes.

The air (Z) flowing in this path cools the upper portion (8a) of the radiator (8). Therefore, the radiator 8 is cooled, and as a result, the heat absorber 10 is cooled, and the dehumidifying ability of the dehumidifier 52 can be improved.

Specifically, the refrigerant that has become hot in the compressor 7 first flows into the side of the upper portion 8a of the radiator 8. That is, in the radiator 8, the upper portion 8a has a higher temperature than the other portions of the radiator 8. Since the air (Z) cools the upper portion (8a) of the radiator (8) having a relatively high temperature, it is possible to cool the radiator (8) effectively. As a result, the radiator 8 is cooled and the heat absorber 10 is cooled, so that the dehumidifying performance of the dehumidifier 52 can be improved.

In addition, since the refrigerant heated to a high temperature by the compressor 7 is gasified, the compressor 7 is connected to the upper portion 8a of the radiator 8. By the cooling in the radiator 8, the refrigerant is liquefied and moves vertically downward. For this reason, in the present embodiment, the air Z passes through the upper portion 8a, thereby enhancing the cooling effect of the radiator 8. However, the upper portion 8a is not necessarily connected to the compressor 7 due to its structure. In such a case, the air Z may be passed in the vicinity of the connection portion on the side of the compressor 7 among the connection portion on the compressor 7 side and the connection portion on the inflator 9 side, which the heat radiator 8 has. Since the connecting portion on the side of the compressor 7 is higher in temperature than the connecting portion on the side of the inflator 9 and the connecting portion on the side of the compressor 7 of the radiator 8 passes through the third dehumidifying path, It is possible to cool the radiator 8 effectively.

Further, the total amount of air (amount of air (X) + amount of air (Y) + amount of air (Z)) can be increased by adding air (Z).

Since the air Z cools the upper portion 8a of the radiator 8, when the air Z is taken out from the air blow-out port 4 to the outside of the main body case 1 from the air suction port 2 or 3, .

As a result, compared with the configuration of the first embodiment, air having a higher temperature, lower humidity, and a larger total air amount is taken out from the air outlet 4 to the outside of the main body case 1.

Therefore, when the clothes are dried in a living space or the like using a dehumidifying device, the effect of drying can be enhanced.

The amount of the air (Y) flowing through the second passage of the heat exchanger (11) is made smaller than the amount of the air (X) flowing through the first passage of the heat exchanger (11).

In this embodiment, it is also preferable that the amount of the air Z is smaller than the amount of the air (Y) flowing through the second passage of the heat exchanger 11. Specifically, it is preferable that the air resistance of the air (Z) is made larger than the air resistance of the air (Y).

According to this configuration, since the amount of air (X) and air (Y) contributing to dehumidification can be sufficiently secured, the dehumidifying ability of the dehumidifying device can be improved more effectively.

(Fourth Embodiment)

Next, the dehumidifying device according to the fourth embodiment will be described with reference to Fig.

The dehumidifying device 53 according to the present embodiment is characterized in that in the heat exchanger 11 in the configuration shown in the first embodiment, as shown in Fig. 9, the upstream opening 18a of the second passage, Is an inclined surface (55) inclined toward the air inlet (2).

In the present embodiment, a circuit board 61 as a control unit for controlling the operation of the dehumidifier 53 is provided above the heat exchanger 11 in the main body case 1. [ The circuit board 61 is arranged close to the heat exchanger 11. [

The air Y sucked into the main body case 1 from the air suction port 2 by the blower 6 passes through the gap formed between the circuit board 61 and the heat exchanger 11 and flows through the gap And flows into the heat exchanger 11 from the side opening 18a. Then, the air is blown out from the air blow-out port 4 to the outside of the main body case 1 through the radiator 8 and the blower 6. [ On the other hand, the air X sucked into the main body case 1 from the air suction port 3 by the blower 6 passes through the heat absorber 10 and is heat-exchanged from the upstream side opening 17a of the first passage (11). The air X then flows out from the downstream opening 17b and is taken out of the main body case 1 through the air blow-out port 4 via the radiator 8 and the blower 6. Then, At this time, heat exchange is performed between the air (X) and the air (Y) in the heat exchanger (11), and condensation occurs in the second passage.

Here, the air passing through the portion of the air (Y) passing through the second passage close to the radiator (8) is less likely to cause condensation because the effect of cooling by the heat exchanger (11) is small.

That is, the air for cooling the air passing through the second passage is air passing through the first passage. The air X flowing through the first passage flows into the heat exchanger 11 from the upstream side opening portion 17a on the side of the heat absorber 10 and flows out from the downstream side opening portion 17b on the radiator 8 side. Therefore, first, the air passing through the portion of the second passage close to the heat absorber 10 is cooled, and thereafter, the air passing through the portion of the second passage near the radiator 8 is cooled.

Therefore, the air (X) flowing through the first passage is first heat-exchanged with the air passing through the portion of the second passage close to the heat absorber (10), and is heated in the heated state to the radiator The air passing through the near portion is cooled. Thereby, the temperature difference between the second passage and the air passing through the portion near the radiator 8 becomes small, and the heat exchange rate is slowed down. It is difficult to cool because the heat exchange rate is slow, and condensation in the second passage is unlikely to occur.

In addition, since the direction of the flow suddenly changes when the air (Y) introduced from the air intake port (2) flows into the second passage of the heat exchanger (11), a variation in air volume occurs in the second passage.

That is, the air (Y) introduced from the air inlet 2 provided on the back surface of the main body case 1 flows in the lateral direction, but the upstream side opening 18a of the second passage is in the vertical The flow of the air is suddenly bent. At this time, the flow of the air (Y) is varied due to the inertia, and more air flows into the portion of the second passage, which is outside the bend, near the radiator (8). Further, since a large amount of air flows in a portion near the radiator 8 of the second passage, a larger amount of cooling heat is required to cool the air to the dew point temperature to generate condensation. However, as described above, air passing through the portion of the second passage close to the radiator 8 is not easily cooled, and consequently, condensation is unlikely to occur.

On the other hand, in the present embodiment, since the upstream opening 18a of the heat exchanger 11 is formed as the inclined surface 55 inclined toward the air inlet port 2, the portion of the second passage near the radiator 8 It is easy to cool the passing air. The details will be described below.

The length in the longitudinal direction of the opening 17b on the downstream side of the first passage extends in the direction of the top 8a of the radiator 8. [ The height after the extension is higher than the downstream end of the heat absorber 10 (the upper end of the heat absorber 10 in Fig. 9). As a result, the upstream-side opening 18a is inclined toward the air inlet 2 side. Then, the passage length of the portion near the radiator of the second passage becomes long, and the time for passing through the heat exchanger 11 can be prolonged. Thereby, even if the temperature difference is small and the heat exchange rate is low, the heat exchange can be performed for a longer time, and as a result, the heat exchange amount can be increased. It is possible to increase the amount of heat exchange, so that the amount of cooling to the air flowing in the portion of the second passage close to the radiator 8 increases, and the generation of condensation can be increased.

Since the length of the downstream side opening 17b of the first passage is extended and the upstream side opening 18a is inclined toward the air intake port 2, And the deviation of the air volume is alleviated. That is, since the passage length of the second passage is increased from the heat absorber 10 to the radiator 8 in the second passage to increase the ventilation pressure loss, the air Y hardly flows into the portion near the radiator 8 Loses. On the other hand, since it is easy to flow into the portion close to the heat absorber 10, the variation in the amount of air flowing through the second passage is alleviated. The amount of air flowing through the portion of the second passage close to the radiator 8 is reduced and the amount of cooling heat required for cooling to the dew point temperature is reduced. Therefore, it is possible to increase the generation of condensation due to the air flowing through the portion of the second passage close to the radiator 8. [

As described above, it is possible to further increase the generation of condensation by the air flowing through the portion of the second passage of the heat exchanger 11 close to the radiator 8, thereby further increasing the dehumidification performance.

(Modified example)

In the four embodiments described above, an example in which the air intake ports are divided into two is shown. However, in the present embodiment, the distribution of the amount of air passing through each passage uses the air resistance of each passage. By doing so, it is not always necessary to divide the air intake port into two, and the same effect can be obtained even with one air intake port.

In the case of distributing the amount of air passing through each passage by using the opening area of the air inlet instead of the air resistance, a plurality of air inlets corresponding to the respective amounts of air may be provided.

Although the control unit is not described in the first and third embodiments, the control unit shown in the second embodiment may be provided in the first and third embodiments. In this case, the control unit sends a control command to the compressor or the blower to operate the dehumidifier. Of course, the control unit shown in the second embodiment may be combined with the control unit shown in the fourth embodiment.

Further, the above-described four embodiments may be carried out simultaneously within a range without contradiction. For example, providing a dehumidifying device having an air flow rate adjusting unit and a third dehumidifying path.
