A louver 13 is provided above the outlet 12 so as to be rotatable, and changes the direction of air blown from the outlet 12. A louver 14 is provided on the upper surface of the housing 1 and behind the outlet 12. The approach wall, which is inclined obliquely downward and linearly, 15 is the upper surface of the housing 1 and the outlet 1
2 is a wall surface of the outlet duct that is provided along the rotation locus of the wind direction changing louver 13 and is provided in front of the outlet 2.

Next, the operation will be described with reference to FIGS. When the blower fan 9 rotates by driving the fan motor 10, air outside the dehumidifier is sucked through the suction port 2, and the sucked air is cooled by the evaporator 3. Moisture contained in the air due to cooling is condensed and drain pan 4
The collected water is collected from a drain pan 4 through a drain port 6 into a drain tank 5. The air having a reduced absolute humidity after passing through the evaporator 3 is then heated by the condenser 8. The heating changes the temperature of the dry air to room temperature. The dry air passes through the bell mouth 11 and the blower fan 9 and is blown out from the outlet 12. Outlet 1
The dry air blown out from 2 is changed in wind direction by a wind direction changing louver 13.

As shown in FIG. 4, when the wind direction changing louver 13 is disposed with the front inclined at a high angle (state A), the dry air blown out from the outlet 12 advances diagonally upward and forward, as indicated by an arrow 20. To form an obliquely upward blowing airflow.
Also, as shown in FIG.
When 3 is arranged (state B), the dry air blown out from the blowout port 12 travels upward and forms an upward blown airflow as shown by an arrow 21.

Further, as shown in FIG. 6, when the wind direction changing louver 13 is disposed at a high angle to the rear (state C), the dry air blown out from the outlet 12 advances obliquely upward and rearward, and An obliquely upward blowing airflow is formed as shown. As shown in FIG. 7, when the louver 13 is arranged substantially horizontally (state D), the dry air blown out from the outlet 12 forms a flow along the run-up wall 14, as shown by an arrow 23. An oblique downward blowing airflow is formed below the horizontal.

As described above, the wind direction changing louver 13 disposed above the outlet 12 is rotated about a substantially horizontal axis to change the direction of the wind direction changing louver 13, thereby obliquely controlling the flow of the dry air. It can be changed widely from upper rear to diagonally lower front. As a result, it is possible to provide a dehumidifier capable of forming a normal-temperature dry blowing airflow according to a multipurpose use situation.

Further, since the approach wall 14 is provided behind the air outlet 12, the dry air whose direction has been changed rearward by the wind direction changing louver 13 further advances obliquely downward. As a result, the dry air can be sent out to a wider area, and the usability for multipurpose use is improved.

Further, as shown in FIGS. 8 (a) to 9 (c), the wind direction changing louver 13 is in the upper blowing state B (FIG. 8).
From (a)), it rotates counterclockwise (FIG. 8 (b)), and reaches state D (FIG. 9 (c)) oriented horizontally. At this time, the wind direction changing louver 13 cannot be rotated unless the outlet duct wall surface 15 has a shape along the rotation trajectory of the wind direction changing louver 13. Therefore, by forming the outlet duct wall surface 15 along the rotation trajectory of the wind direction changing louver 13, it is possible to have a wide air flow width from upper blowing to lower blowing with a single wind direction changing louver 13. became. As a result, the control of the room-temperature drying blow airflow according to the use condition of various purposes is realized, and an effect that a high-performance and inexpensive dehumidifier can be provided as compared with the conventional dehumidifier can be obtained.

The wind direction changing louver 13 has been rotated by more than 90 degrees from the state A to the state D.
For this reason, the dry air can be sent not only upward and backward but also forward, and a very wide blown airflow can be formed. As a result, it is possible to provide a room-temperature drying blow airflow according to a variety of purposes of use with a single blower fan, thereby providing an overwhelmingly high-performance and inexpensive dehumidifier as compared with a conventional dehumidifier. The effect is obtained.

Further, the suction port 2 is arranged below the approach wall 14. Thus, the approach wall 14 and the suction port 2
Are arranged on the same surface side, the approach wall 14 and the suction port 2 can be placed on the back side of the user. For this reason, the direction of the airflow of the dry air flowing along the approach wall 14, which is the main radiation part of the noise, and the direction of the suction port 2 sandwich the dehumidifier body on the opposite side to the user, and are felt by the user during operation. The noise value can be effectively reduced.

Embodiment 2 FIG. Next, a dehumidifier according to Embodiment 2 will be described. FIG. 10 is a vertical sectional view of the dehumidifier according to the second embodiment as viewed from the side. The second embodiment is different from the first embodiment shown in FIG.
In place of 4, a curved run-up wall 2 rising upward
4 is provided. Other configurations are the same as or equivalent to the first embodiment. The same or equivalent components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

As shown in FIG. 10, the approach wall 24 is provided behind the outlet 12, and when the length L of the approach wall 24 in the horizontal direction is the same as the approach wall 14 of FIG.
The angle θ between the wall surface tangent 1 at the rear end and the horizontal line h
d is configured to be larger than the approach wall 14. For this reason, in the state D in which the wind direction changing louver 13 is arranged in the horizontal direction as shown in FIG. 11, the blown airflow forms a flow along the approaching wall 24 as shown by the arrow 25, and blows downward from below the horizontal. An airflow is created. At this time, the approach wall 24 creates a downward blowing airflow having a larger downward angle than that of the straight approach wall 14.

Therefore, it is possible to form not only the conventional upward blow airflow but also the downward blow airflow having a very large downward angle. Can be As a result, the control of the room temperature drying blow airflow according to the use situation of various purposes is realized, and an effect that a high-performance and inexpensive dehumidifier can be provided as compared with a conventional dehumidifier can be obtained.

Embodiment 3 Next, a dehumidifier according to Embodiment 3 will be described. FIG. 12 is a vertical sectional view of the dehumidifier according to the third embodiment as viewed from the side. The third embodiment differs from the second embodiment shown in FIG. 10 in that a wind direction changing louver 26 having a surface 26a facing the approach wall 24 is provided instead of the wind direction changing louver 13. Other configurations are the same as or similar to those of the second embodiment. Note that the same or equivalent components as those of the second embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 13, the wind direction changing louver 2
In the state D in which the nozzles 6 are arranged horizontally, the blown airflow forms a flow along the approach wall 24 as shown by an arrow 27,
A downward blowing airflow is created below horizontal. Since the wind direction changing louver 26 has a surface 26 a facing the approach wall 24, the main flow of the blown air flows to the approach wall 24,
It becomes more susceptible to the Coanda effect, and the entire flow becomes a downward blowing airflow further downward than horizontal.

FIG. 14 is a graph showing the relationship between the wind direction and the wind speed of the dehumidifier according to the third embodiment. FIG. 15 is a graph showing the relationship between the wind direction and the wind speed of the dehumidifier according to the first embodiment. The horizontal axis represents the wind direction angle in which the downward direction is positive when the horizontal direction is 0 °, and the vertical axis represents the value obtained by dimensioning the wind speed Vi at each wind direction angle by the average wind speed average V.
According to this, assuming that the mainstream of the blown airflow has the fastest wind speed, the dehumidifier according to Embodiment 1 in which the wind direction changing louver 13 and the approach wall 14 do not have a facing surface (see FIG. 1).
In this case, the lower blowing angle is smaller than the angle θd formed by the wall surface tangent 1 at the rear end of the approach wall 14 and the horizontal plane h.

On the other hand, when the length LR of the surface 26a of the wind direction changing louver 26 facing the approach wall 24 is 0.2 times or more the horizontal length L of the approach wall 24, the lower blowing angle is Is substantially equal to the angle θd between the wall surface tangent 1 at the rear end of the approach wall 24 and the horizontal plane h. That is, when the wind direction changing louver 26 is provided with the surface 26a facing the run-in wall 24, the entire flow becomes a downward blowing airflow downward from horizontal as compared with a case where the louver 26 is not provided.

As a result, it is possible to form not only the conventional upward blow airflow but also the downward blow airflow having a very large downward angle. It can be broadened. As a result, the control of the room-temperature drying blow airflow according to the use condition of various purposes is realized, and an effect that a high-performance and inexpensive dehumidifier can be provided as compared with the conventional dehumidifier can be obtained.

The fourth embodiment differs from the first embodiment shown in FIG. 1 in that a wind direction changing louver 28 composed of two vanes is provided instead of the wind direction changing louver 13 composed of one vane. It is a point. Other configurations are the same as or equivalent to the first embodiment. The same or equivalent components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

As shown in FIG. 16, when the wind direction changing louver 28 composed of two vanes is arranged horizontally, the wind direction changing louver 13 composed of one vane is used.
Compared to (see FIG. 1), the wind direction changing louver 28 can dispose the vane closer to the blower fan 9, so that the flow can be deflected at a high wind speed. As a result, the deflection energy received by the airflow is increased, creating a downward blowing airflow having a larger downward angle.

As a result, it is possible to form a blown airflow in a much larger range, and a room-temperature dry blown airflow can be formed by a single blower fan according to a variety of intended use conditions. As a result, it is possible to obtain a high-performance and inexpensive dehumidifier.

Embodiment 5 Next, a dehumidifier according to Embodiment 5 will be described. FIG. 17 is an upper cross-sectional view of the dehumidifier of Embodiment 5 as viewed from the side. The fifth embodiment is different from the fourth embodiment shown in FIG. 16 in that the wind direction changing louver 28 composed of two vanes having substantially the same area is replaced with two vanes having different areas. The point is that a wind direction changing louver 29 is provided. Other configurations are the same as or similar to those of the fourth embodiment. The same or equivalent components as those of the fourth embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 17, the wind direction changing louver 2
When 9 is located substantially horizontally, the area of the lower vane 29a is larger than that of the other vane 29b. As described above, since the area of the vane 29a close to the blower fan 9 is large, the deflection energy received by the flow becomes larger, and a downward blowing airflow having a larger downward angle is created.

As a result, it is possible to form an extremely enormous wide range of blowout airflow, and it is possible to form a normal-temperature dry blowout airflow according to a variety of intended use conditions with a single blower fan. In comparison, the effect that a high-performance and inexpensive dehumidifier can be provided is obtained.

The sixth embodiment differs from the first embodiment shown in FIG. 2 in that an operation unit 30 for controlling the rotation angle of the wind direction changing louver 13 is further provided. Other configurations are the same as or equivalent to the first embodiment. The same or equivalent components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

As shown in FIG. 18, the operation unit 30 is provided on the opposite side of the approach wall 14 through the outlet 12. Here, the blown airflow from the blowout port 12 is mainly directed to the rear of the housing 1 by the wind direction changing louver 13, so that the blown airflow flows near the operation unit 30 disposed on the front surface of the housing 1. There is no. For this reason, when the user touches the operation unit 30 to change the operation state or the like during the operation of the dehumidifier, the user is not exposed to the blowing airflow and does not cause discomfort, and the operation operation can be performed comfortably. can get.
