Description

dehumidifier

The present disclosure relates to a dehumidifier equipped with a louver.

Traditionally, dehumidifiers have been used not only to remove moisture from the air, but also as a substitute for dryers by directing dry air to laundry containing moisture. Multi-purpose use is required, and the structure allows the direction of the blowing air to be changed significantly depending on the type of use.

In Patent Document 1, a dehumidifier is equipped with an air outlet 18 that is open from the top surface to the rear surface, and has two vanes 19a and 19b, long and short, with a support shaft 20 rotatably supported on the inner wall of the air outlet 18. The wind direction changing louver 19 is provided with a slope portion 21 that is flush with the rear opening of the air outlet 18 on the upper surface of the dehumidifier and is inclined slightly downward toward the rear. By rotating , the angle of the air blowing direction can be changed arbitrarily within the range from upward and slightly forward to horizontal and slightly downward.

When the two vanes 19a and 19b of the wind direction changing louver 19 are set in the upward position, the rear opening of the air outlet 18 is closed by the second long vane 19b, and the airflow is directed upward. It's blown out. When the wind direction changing louver 19 is placed in a horizontal position, the open opening on the top surface of the air outlet 18 is closed by both the first and second vanes, and the airflow is directed to the rear surface. The air is blown out from the opening toward the rear and slightly downward along the slope portion 21 provided on the top surface of the dehumidifier. At this time, the wind direction changing louver 19 not only covers the entire surface of the air outlet 18, but also protrudes from the air outlet 18 toward the slope portion 21 extending rearward.

Patent No. 3807184

In Patent Document 1, when the air outlet 18 is open from the top surface to the rear surface of the dehumidifier and does not include a slope portion 21 that continues flush with the air outlet 18 and faces rearward, the air direction changing louver 19 is oriented sideways in the horizontal direction. When the airflow direction changing louver 19 protrudes from the air outlet 18, the airflow direction changing louver 19 protrudes from the rear surface of the dehumidifier. This is unfavorable from both the external design point of view and the safety point of view. On the other hand, if the wind direction changing louver 19 does not protrude from the air outlet 18 in the air outlet direction, the closer the airflow is from the air outlet 18 to the rear opening, the longer the vane will turn the upwardly blown air to the rear. There was a problem in that the airflow was not blown out backwards but upwards or diagonally upward at the rear.

The present disclosure efficiently changes the direction of the blown airflow horizontally even when the louver does not protrude from the opening through which the blown air is blown out from the housing when the louver is supported in a horizontal position. Aim to change direction.

A dehumidifier according to the present disclosure includes a casing in which an inlet and an outlet are formed, and an air blower that generates an airflow from the inlet to the outlet. and a dehumidifying means for removing moisture from the air sucked into the air. The blower is equipped with a louver on the downstream side of the outlet, which is made up of a plurality of vanes and is rotatably supported, and which changes the direction of the air blown from the upper and front openings. Between the outlet and the louver, there is a protrusion that protrudes from the front wall of the housing so as to partially block the upper part of the outlet and guides the air from the outlet to the rear. When supported in a forward horizontal position, the leeward end of the vane does not protrude forward from the front opening, and the leeward end of the vane is arranged forward of the rear end of the protrusion. It is.

According to the present disclosure, when the leeward side portion of the vane is supported in a horizontally forward posture, the airflow from the outlet near the front opening is guided rearward by the protrusion, so the outlet The airflow from the air outlet is efficiently blown onto the vane, and it becomes easy to ensure the length of the vane to laterally divert the airflow from the air outlet. Furthermore, since the leeward end of the vane is placed forward of the rear end of the protrusion, the airflow from the outlet near the front opening will not escape upward from the leeward end of the vane. It can be suppressed. Therefore, the direction of the airflow from the air outlet can be efficiently changed to the lateral direction.

The rear case 10b is a member that forms the rear surface portion of the case 10. The rear case 10b is fixed to the front case 10a with, for example, screws.

As shown in FIGS. 2 and 3, the case 10 is formed with a first suction port 11a, a second suction port 11b, and an air outlet 12. The first suction port 11a and the second suction port 11b may be collectively referred to as the suction port 11, and are openings for taking in air from the outside of the case 10 to the inside. The air outlet 12 is an opening through which airflow passes in order to blow out air from the inside of the case 10 to the outside. The first suction port 11a and the second suction port 11b are formed in the rear surface portion of the case 10. In addition, in this embodiment, although the case where it is comprised with the 1st suction port 11a and the 2nd suction port 11b is demonstrated as an example, it may be comprised with a single suction port.

Further, in the first embodiment, the front opening 12a through which the air passing through the outlet 12 is blown out to the front of the housing is opened from the top surface of the case 10 to the front, and the front opening 12a and the housing of the dehumidifier 1 are connected to each other. It is constructed flush and continuous with the front of the body. Further, the top opening 12b through which the air passing through the outlet 12 is blown upward of the case 10 is open to the top surface of the case 10, and the top opening 12b of the outlet 12 and the top surface of the casing of the dehumidifier 1 are connected to each other. is constructed continuously on the same plane. Since the front opening 12a and the front surface of the casing of the dehumidifier 1 are configured to be flush and continuous, and the top opening 12b and the top surface of the casing of the dehumidifier 1 are configured to be flush and continuous, Design quality is not impaired.

The dehumidifier 1 includes a suction port cover 14 that covers the first suction port 11a and the second suction port 11b. The suction port cover 14 is formed, for example, in a mesh shape. This suction port cover 14 prevents foreign matter from entering the inside of the case 10 via the first suction port 11a and the second suction port 11b. For example, the suction port cover 14 is formed to be detachable from the rear case 10b.

The dehumidifier 1 includes a net 13 at the air outlet 12. The net 13 is formed, for example, in a lattice shape. This net 13 prevents foreign matter from entering the inside of the case 10 from the air outlet 12.

Additionally, the dehumidifier 1 includes an operation display section 15. The operation display section 15 is for a user to operate the dehumidifier 1. Further, the operation display section 15 displays the status of the dehumidifier 1 and the like to the user.

Control board 15a is arranged inside rear case 10b.

A board box 16 containing a power supply board (not shown) is arranged in the rear case 10b.

Additionally, the dehumidifier 1 includes a fan 21. The fan 21 is a blowing means that takes air into the case 10 and sends the taken air to the outside of the case 10. Fan 21 is housed inside front case 10a. In the dehumidifier 1, main air flows from a first suction port 11a, passes through a HEPA filter 41 and an activated carbon filter 42, which are an example of air purifying means, to be described later, and reaches an evaporator 31, which is an example of a dehumidifying means, which will be described later. An air path leading from the second suction port 11b to the air outlet 12 via a bypass air path leading to the evaporator 31 without passing through the air purifying means, and an air path leading to the air outlet 12 through the air purifying means are formed. . The fan 21 is a device that generates airflow from the first suction port 11a and the second suction port 11b to the air outlet 12.

The main air path is equipped with a HEPA filter 41 and an activated carbon filter 42, which are air purifying filters for purifying the air, as an example of air purifying means for removing dust and odor from the air. The HEPA filter 41 and activated carbon filter 42 are removably housed in the rear case 10b.

The HEPA filter 41 is a filter that collects fine dust in the air. The activated carbon filter 42 is a filter that deodorizes odors in the air. At the rear of the activated carbon filter 42, a lattice portion 10c is arranged with a gap therebetween. An evaporator 31 is arranged at a distance behind the grid section 10c. The airflow flowing through the main air path and the airflow flowing through the bypass air path are configured to merge in the space before and after the grid portion 10c.

The bypass air passage is provided with a shutter 17 that can open and close the bypass air passage. The shutter 17 is arranged downstream of the second suction port 11b. The shutter 17 is rotatably supported on the upper and lower end wall surfaces of the wall surfaces forming the bypass air passage. The rotational position of the shutter 17 is controlled by a control board 15a serving as a control means driving a shutter drive motor (not shown) that rotates the shutter 17.

In the air cleaning operation mode, which is one of the operation modes of the dehumidifier 1, the control board 15a controls the shutter 17 to rotate to a position that blocks the entrance of the bypass air path, so that the air flows through the first suction port. The air is sucked in only from the air outlet 11a, passes through a main air path including a HEPA filter 41 and an activated carbon filter 42, and is blown out from the air outlet 12.

In the dehumidification operation mode, which is another operation mode of the dehumidifier 1, the control board 15a controls the shutter 17 to rotate to a position that opens the entrance of the bypass air passage, so that air is mainly transferred to the second suction port. 11b, passes through the bypass air path, and is blown out from the air outlet 12.

A motor 21a is housed inside the case 10. The motor 21a is a device that rotates the fan 21. In the first embodiment, the fan 21 and the motor 21a are arranged inside the front case 10a. That is, it is arranged on the front side of the dehumidifier 1. Motor 21a is connected to fan 21 via shaft 21b. The rotational operation of the motor 21a is controlled by a control board 15a which is a control means.

Further, the dehumidifier 1 includes an evaporator 31, a condenser 32, a compressor (not shown), and a pressure reducing device (not shown) as an example of a dehumidifying means for removing moisture contained in the air. The evaporator 31 and the condenser 32 together with the compressor and the pressure reduction device form a refrigerant circuit. The evaporator 31, condenser 32, compressor, and pressure reducing device are housed in the case 10. A compressor driving motor of the compressor is controlled by a control means. In the first embodiment, the evaporator 31 and the condenser 32 are surrounded by the rear case 10b. The rear case 10b has a lattice portion 10c. The grid portion 10c is an opening having a cross-sectional area comparable to that of the evaporator 31.

The evaporator 31, compressor, condenser 32, and pressure reducing device are connected in order via piping (not shown) and the like. A refrigerant flows through a refrigerant circuit formed by an evaporator 31, a compressor, a condenser 32, and a pressure reducing device.

The evaporator 31 and the condenser 32 are heat exchangers for exchanging heat between the refrigerant and air. A compressor is a device that compresses refrigerant. A pressure reducing device is a device that reduces the pressure of a refrigerant. The pressure reducing device is, for example, an expansion valve or a capillary tube.

The air passing through the evaporator 31 undergoes heat exchange with the refrigerant flowing through the evaporator 31. As described above, the refrigerant whose pressure has been reduced by the pressure reducing device flows through the evaporator 31 . A refrigerant having a lower temperature than the air taken into the case 10 flows through the evaporator 31 . The refrigerant flowing through the evaporator 31 absorbs heat from the air passing through the evaporator 31 .

The air passing through the evaporator 31 has heat absorbed by the refrigerant flowing through the evaporator 31. That is, the air passing through the evaporator 31 is cooled by the refrigerant flowing through the evaporator 31. As a result, moisture contained in the air passing through the evaporator 31 is condensed. In other words, condensation occurs. Moisture in the condensed air is removed from the air as liquid water. The removed water is stored in a tank 19 provided inside the case 10, for example. This tank 19 is formed to be detachable from the case 10.

The air that has passed through the evaporator 31 is sent to the condenser 32. Heat exchange occurs between the air passing through the condenser 32 and the refrigerant flowing through the condenser 32. The refrigerant flowing through the condenser 32 is cooled by the air passing through the condenser 32 . The air passing through the condenser 32 is heated by the refrigerant flowing through the condenser 32 .

The air that has passed through the condenser 32 is in a dry state compared to the air outside the dehumidifier 1. This dry air passes through the fan 21. The air that has passed through the fan 21 passes through the air outlet 12. The direction of the airflow that has passed through the air outlet 12 is changed by a louver 18, which will be described later, and is sent out of the case 10 from the front opening 12a or the upper opening 12b. In this way, the dehumidifier 1 dehumidifies the air. Further, the dehumidifier 1 supplies dry air to the outside.

Additionally, the dehumidifier 1 has a humidity sensor (not shown). A humidity sensor is placed inside the case 10. An opening (not shown) communicating with the outside of the case 10 is provided in the case 10 near the humidity sensor. Humidity detection information is acquired by the control means, and the humidity sensor can measure indoor humidity. The measurement results of the humidity sensor are displayed on the operation display unit 15 by the control board 15a to which the humidity detection information acquired by the control means is transmitted.

It also has a dust sensor (not shown). The dust sensor is arranged inside the case 10. An opening (not shown) communicating with the outside of the case 10 is provided in the vicinity of the dust sensor of the case 10 . The dust sensor acquires dust detection information by the control means and can measure the amount and concentration of dust in the room. The dust sensor has the ability to detect particles of 0.1 μm, for example. The detection result of the dust sensor is displayed on the operation display section 15 by the control board 15a to which the dust detection information acquired by the control means is transmitted.

It also has a gas sensor (not shown). The gas sensor is arranged inside the case 10. An opening (not shown) communicating with the outside of the case 10 is provided in the case 10 near the gas sensor. Gas detection information is acquired by the control means, and the gas sensor can measure the odor of indoor air. The measurement results of the gas sensor are displayed on the operation display section 15 by the control board 15a to which the gas detection information acquired by the control means is transmitted.

Additionally, the dehumidifier 1 includes a louver 18 as shown in FIGS. 4 and 5. As shown in FIGS. 2, 6 to 9, etc., the louver 18 is a wind direction changing louver for changing the direction of airflow blown out from the front opening 12a and the top opening 12b. The louver 18 is arranged on the downstream side of the air outlet 12. The louver 18 has a support shaft 18c rotatably supported on the inner wall above the air outlet 12, and is disposed above the air outlet 12. The support shaft 18c is connected to a louver drive motor (not shown) directly or via a gear, and by controlling the louver drive motor with a control board 15a, which is a control means, the louver 18 rotates and the front surface is rotated. The direction of airflow blown out from the opening 12a and the top opening 12b is changed.

As shown in FIGS. 4 and 5, the louver 18 is composed of two plate-shaped vanes. In other words, the first vane 18a and the second vane 18b are formed, one of which is long and the other of which is short, along the direction in which the airflow from the outlet 12 is guided. In each case, the length along the direction in which the discharged airflow is guided (the length in the transverse direction (short side)) is shorter than the length in the direction perpendicular to this direction (the length in the longitudinal direction (long side)) . In other words, the first vane 18a has a longer short side than the second vane 18b. As shown in FIGS. 4, 6, etc., the first vane 18a is a flat plate. The second vane 18b has a plate shape bent in the middle. Using the flow of air guided by the first vane 18a and the second vane 18b, the leeward side portion 18b1 of the second vane 18b is configured to be parallel to the leeward side portion 18a1 of the first vane 18a. The leeward side end, which is the tip of the leeward side portion 18a1 of the first vane 18a, and the leeward side end, which is the tip of the leeward side portion 18b1 of the second vane 18b, are located at opposing positions. It is in. The windward side portion 18b2 of the second vane 18b is provided with an inclined portion 18d bent in a direction away from the windward side portion 18a2 of the first vane 18a.

As shown in FIG. 6, between the air outlet 12 and the louver 18, there is a protrusion 22 that protrudes from the front wall side of the housing (back side of the front case 10a) so as to partially block the upper part of the air outlet 12. Equipped with The protrusion 22 forms a slope that protrudes rearward as it goes upward from the air outlet 12. The upper end of this slope is the rear end of the protrusion 22, and the upper surface of the protrusion 22 is a horizontal surface that continues to the rear end of the protrusion 22.

When the first vane 18a is supported in a horizontally forward and sideways posture, the leeward end of the leeward side portion 18a1 of the first vane 18a of the louver 18 and the leeward side portion of the second vane 18b The leeward end of 18b1 does not protrude forward from the front opening 12a and does not protrude forward from the front case 10a. Further, when the first vane 18a is supported in a horizontally forward and sideways posture, the leeward end of the leeward portion 18b1 of the second vane 18b is arranged forward of the rear end of the protrusion 22. Ru. It is desirable that the second vane 18b and the protruding portion 22 overlap with each other by at least 5 mm along the horizontal direction (front-back direction). That is, it is desirable that the leeward end of the leeward portion 18b1 of the second vane 18b be disposed 5 mm or more forward of the rear end of the protrusion 22. By arranging it in this way, the airflow blown out from the outlet 12 is suppressed from going around from the rear end of the protrusion 22 to the leeward end of the leeward side portion 18b1 of the second vane 18b. It is possible to prevent the airflow blown from the vane 12 from escaping upward from the leeward end of the leeward portion 18b1 of the second vane 18b.

As shown in FIG. 6, when the first vane 18a of the louver 18 is supported in a horizontally forward and sideways posture, the upper opening 12b (see FIG. 7) of the air outlet 12 is opened by the first vane 18a. In the closed state, the airflow is blown out from the front opening 12a of the outlet 12 toward the front. Hereinafter, it is assumed that the first vane 18a represents the attitude of the louver 18. As shown by arrow A in the figure, the airflow blown out from the rear side of the dehumidifier 1 through the air outlet 12 flows between the first vane 18a and the second vane 18b, is deflected by both vanes, and is directed forward. is blown out. As shown by arrow B in the figure, the airflow blown out from the front side of the dehumidifier 1 through the air outlet 12 is guided backward by the slope of the protrusion 22, and then forwarded by the lower surface of the second vane 18b. He was turned and blown forward. Since the protrusion 22 forms a slope that protrudes rearward from the front wall of the housing as it goes upward from the air outlet 12, the airflow blown out from the air outlet 12 can be guided to the rear of the air outlet 12. Therefore, the airflow from the outlet 12 is efficiently blown onto the second vane 18b, and it is easy to ensure the length of the second vane 18b for turning the airflow from the outlet 12 laterally. .

As shown in FIG. 7, when the louver 18 is supported in a posture that faces forward and diagonally downward, the airflow blown out from the air outlet 12 is divided into the airflow blown out from the front opening 12a and the airflow blown out from the upper opening 12b. Divided. The airflow blown out from the rear side of the dehumidifier 1 through the air outlet 12 flows between the first vane 18a and the second vane 18b, as shown by arrow C in the figure, is deflected by both vanes, and is directed forward. It is blown out diagonally downward. Further, as shown by arrow D in the figure, since the louver 18 is disposed diagonally forward and downward, a part of the airflow blown out from the rear side of the dehumidifier 1 of the air outlet 12 is directed toward the first vane 18a. The air is blown diagonally rearward and upward from a gap created between the rear edge of the windward side portion 18a2 of the dehumidifier 1 and the top surface of the dehumidifier 1. As shown by arrow E in the figure, the airflow blown out from the front side of the dehumidifier 1 through the air outlet 12 is guided backward by the slope of the protrusion 22, and then diagonally forward by the lower surface of the second vane 18b. It is attracted by the downward flow of air and is diverted, blowing out diagonally downward.

The inclined portion 18d of the second vane 18b is at least parallel to the air outlet surface of the air outlet 12 when the louver 18 is supported in a forward and diagonally downward position, and the inclined portion 18d of the second vane 18b is It is bent in the direction of the air outlet 12 so that the angle X formed is smaller than 180 degrees. As a result, the airflow guided rearward by the slope of the protrusion 22 is prevented from merging with the airflow indicated by arrow D by the lower surface of the slope 18d of the second vane 18b.

As shown in FIG. 8, when the louver 18 is arranged and supported in a vertically upward position, the airflow blown out from the air outlet 12 is not obstructed by the first vane 18a and the second vane 18b, and the airflow is not obstructed by the upper surface open opening 12a. It is blown upward from.

As shown in FIG. 9, when the louver 18 is supported in an upwardly rearward posture, the airflow blown out from the air outlet 12 is blown out from the upper opening 12a. As shown by arrow F in the figure, the airflow blown out from the rear side of the dehumidifier 1 through the air outlet 12 is directed rearward and diagonally upward from the gap created between the top surface of the first vane 18a and the top surface of the dehumidifier 1. is blown out. As shown by arrow G in the figure, the airflow blown out from below the louver 18 of the air outlet 12 flows between the first vane 18a and the second vane 18b, is turned by both vanes, and is directed rearward and diagonally upward. is blown out.

When the louver 18 is supported in an upward rearward position, the angle Compared to the case where the windward side portions 18b2 of the vanes 18b are parallel, the windward inlets of the first vane 18a and the second vane 18b are formed larger. As a result, the airflow from the air outlet 12 can be efficiently guided into the first vane 18a and the second vane 18b.

As described above, the dehumidifier of Embodiment 1 includes a casing in which an inlet and an outlet are formed, and an air blower that generates an airflow from the inlet to the outlet, and inside the casing, a dehumidifying means for removing moisture from the air sucked into the housing from the suction port, and the air outlet is provided in an upper part of the front side of the housing so as to open upward, and is connected to the upper surface of the housing and this upper surface. The front side has a top opening and a front opening, respectively, and the downstream side of the air outlet is made up of a plurality of vanes that are rotatably supported and change the direction of the air blowing from the top opening and the front opening. When the louver is provided and the leeward end of the vane is supported in a horizontal forward posture, the leeward end of the vane does not protrude forward from the front opening, so the design is not impaired.

In addition, between the air outlet and the louver, there is a protrusion that protrudes from the front wall side of the housing so as to partially block the upper part of the air outlet and guides the air from the air outlet to the rear. When the leeward end is supported horizontally forward, the airflow from the outlet near the front opening is guided rearward by the protrusion, and the airflow from the outlet is efficiently blown onto the vane. This makes it easy to ensure the length of the vane to divert the airflow from the outlet in the lateral direction, and the direction of the airflow blown out from the front opening can be efficiently directed laterally, that is, in the forward direction. Can be changed.

Furthermore, when the leeward end of the vane is supported in a horizontally forward position, the leeward end of the vane is positioned forward of the rear end of the protrusion, so that It is possible to prevent the airflow from the outlet from escaping upward from the leeward end of the vane. Therefore, the direction of the airflow from the air outlet can be efficiently changed to the lateral direction.

In addition, the louver is composed of two plate-shaped vanes, and when the leeward side part of the vane of the louver is supported in a horizontally forward position, the first vane that closes the upper opening is closed by the second vane. The length of the short side is longer than that of the first vane, and the windward side part of the second vane has an inclined part bent in a direction away from the windward side part of the first vane, so that it is guided backward by the slope of the protruding part. The airflow merges with the airflow blown diagonally backward and upward from the gap created between the trailing edge of the windward side of the first vane and the top surface of the dehumidifier by the lower surface of the sloped part of the second vane. can be suppressed.

Furthermore, since the front opening and the front surface of the casing are continuous and flush, the design is not impaired.

Furthermore, since the top surface opening and the top surface of the casing are continuous and flush, the design is not impaired.

Furthermore, since the protrusion forms a slope that protrudes rearward from the front wall of the casing as it goes upward from the air outlet, it is possible to efficiently guide the airflow blown out from the air outlet rearward.

Embodiment 2.
The configuration of a dehumidifier according to Embodiment 2 of the present disclosure will be described below, focusing on the differences from Embodiment 1. Note that the present disclosure is not limited to the following embodiments, and various modifications and changes can be made without departing from the spirit of the present disclosure.

The configuration of the protrusion 22a formed at the end of the air outlet 12 on the front side of the dehumidifier 1 in Embodiment 2 will be described. FIG. 10 is a sectional view of the air outlet 12 when the louver 18 of the second embodiment is arranged horizontally. FIG. 11 is a cross-sectional view of the air outlet 12 when the louver 18 of the second embodiment is arranged diagonally downward. FIG. 12 is a cross-sectional view of the air outlet 12 when the louver 18 of the second embodiment is arranged diagonally upward.

In the second embodiment, as shown in FIG. 10, the outlet 12 is provided with a protrusion 22a on the back side of the front wall of the casing of the dehumidifier 1 so as to partially block the outlet 12.

The protrusion 22a forms a gentle curved surface from the middle of the front case 10a that accommodates the fan 21 and the motor 21a toward the front opening 12a of the air outlet 12 so as to partially block the air outlet 12. That is, this curved surface is a curved surface that protrudes rearward from the front wall side of the housing as it goes upward. This curved surface is formed from at least the outer diameter of the fan 21.

When the louver 18 is supported in a horizontally forward and sideways posture, the leeward side portion 18a1 of the first vane 18a and the leeward side portion 18b1 of the second vane 18b of the louver 18 are exposed from the front opening 12a. It does not protrude forward and does not protrude forward from the front case 10a. Further, when the first vane 18a is supported in a horizontally forward and sideways posture, the end of the leeward side portion 18b1 of the second vane 18b is arranged forward of the rear end of the protrusion 22. It is desirable that the second vane 18b and the protruding portion 22 are arranged to overlap with each other by at least 5 mm along the horizontal direction (front-back direction). By arranging it in this way, it is possible to suppress the airflow blown out from the air outlet 12 from escaping upward from the tip of the leeward side portion 18b1 of the second vane 18b.

As shown in FIG. 10, when the louver 18 is supported in a horizontally forward and sideways position, the airflow blown out from the front side of the dehumidifier 1 from the air outlet 12, as shown by the arrow H in the figure, is After being guided rearward by the curved surface of the protrusion 22a, it is turned forward by the second vane 18b and blown out forward.

As shown in FIG. 11, when the louver 18 is supported diagonally downward in the front direction, the airflow blown out from the front side of the dehumidifier 1 of the air outlet 12 is directed toward the protrusion, as shown by the arrow J in the figure. After being guided rearward by the curved surface of 22a, it is turned diagonally downward by the second vane 18b and is blown diagonally downward.

In this way, the protrusion 22a forms a gentle curved surface from the middle of the front case 10a that accommodates the fan 21 and the motor 21a toward the front opening of the air outlet 12 so as to partially block the air outlet 12. Accordingly, the contact friction between the protrusion 22a and the airflow guided rearward by the protrusion 22a can be reduced, and the airflow blown out from the outlet 12 can be efficiently guided rearward. Furthermore, the effects of pressure loss reduction and noise reduction can be obtained.

In this way, the protrusion forms a curved surface that protrudes rearward from the front wall of the casing as it goes upward from the air outlet, so it is possible to efficiently guide the airflow blown out from the air outlet rearward.

The dehumidifier according to the present disclosure can be used, for example, to dehumidify indoor air.
