DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner such as a dehumidifier for removing moisture from ambient air, and more particularly to an air conditioner capable of easily adjusting the direction of air blow from an air outlet. About the machine.

[0002]

2. Description of the Related Art Generally, a drier for drying an object to be dried such as laundry is provided with a drying chamber for storing the object to be dried, and sends dry air into the drying chamber to dry the object to be dried. In such a dryer, it is necessary to seal the drying chamber in order to prevent moisture exchange between the drying air sent into the drying chamber and the outside air. Further, since the drying chamber is provided, the apparatus becomes large, and a large installation space is required.

Therefore, conventionally, a dehumidifier, which is an air conditioner, is brought into a relatively small room in which an object to be dried is suspended, and the object to be dried is dried by dehumidifying the dehumidifier. A dehumidifier having a portable drying function suitable for this usage has been commercialized.

[0004] As described above, when the object to be dried is dried using a portable dehumidifier having a drying function, the drying air is blown from the dehumidifier in the direction of the object to be dried. The drying speed can be increased, and the efficiency of the drying operation can be improved. Therefore, in the dehumidifier having the drying function, it is necessary to change the blowing direction of the outlet of the dry air in a wide range.

[0005] Such a configuration for changing the blowing direction of the outlet over a wide range is generally required not only in dehumidifiers having a drying function but also in other air conditioners.

For this reason, Japanese Patent Application Laid-Open No. 63-140247 discloses a front outlet 44 and a lower outlet 45 of an indoor unit main body 41 of a ceiling-suspended air conditioner as shown in FIG.
A damper 42 that is rotatable about the vicinity of a partition wall 46 that partitions the lower surface is provided, and the rotational position of the damper 42 is defined as a position at which the lower surface outlet 45 is closed (a position indicated by a solid line in FIG. The position where the outlet 44 is closed (FIG. 10)
(A) The position indicated by the broken line in the middle, or the intermediate position (FIG.
(Position shown in (B)) is disclosed, in which the air blowing direction can be changed to the front direction, the lower surface direction, or both the front and lower surfaces.
In this configuration, furthermore, grilles 43 and 47 for adjusting the wind direction are provided on the front outlet 44 and the lower outlet 45, respectively.
Are provided rotatably.

Also, Japanese Patent No. 2581773 discloses that
As shown in FIG. 11, a wind direction plate 53 is rotatably provided at an air outlet 52 on the cabinet upper surface 51, and the rotation direction of the wind direction plate 53 is selectively switched, so that the air blowing direction is obliquely upward and forward (FIG. )) Or upward (FIG. 11).
(See FIG. 11B), and further discloses a configuration of a dehumidifier in which the outlet 52 can be closed (see FIG. 11C) when the operation is stopped.

[0008]

However, as disclosed in Japanese Patent No. 2581773, the wind direction is adjusted by rotating a wind direction plate 53 at a single air outlet 52 provided on an upper surface 51 of a cabinet. The configuration has a problem that the wind direction cannot be changed over a wide range.

Further, in the configuration disclosed in Japanese Patent Application Laid-Open No. 63-140247, both the switching of the rotational position of the damper and the adjustment of the rotational positions of the grills 43 and 47 are required, and the work of adjusting the blowing direction is required. Is complicated.

An object of the present invention is to provide an air conditioner capable of changing the air blowing state in various ways with a simple configuration and operation.

[0011]

The present invention has the following arrangement as means for solving the above-mentioned problems.

(1) A plurality of air outlets opened in different directions from each other, a wind direction plate for changing a blowing direction through one air outlet in accordance with a rotation position, and a plurality of air direction plates operating integrally with the wind direction plate. A distribution plate for changing the ratio of the amount of air blown to the air outlet is provided (claim 1).

In this configuration, the direction of air flow through one air outlet changes according to the rotational position of the air direction plate, and the ratio of the air flow to the plurality of air outlets changes with the distribution plate. Therefore, by adjusting the rotational position of the wind direction plate, both the ratio of the amount of air blown from the plurality of outlets and the direction of air blown through at least one outlet are changed.

(2) The distribution plate has a function of changing the ratio of the amount of air blown to the plurality of outlets, and a distribution plate on the upstream side in the air flow direction, and a downstream side in the air flow direction with a predetermined angle to the distribution plate. And a guide plate that forms an air blowing direction for a different air outlet from an air outlet in which the air direction plate changes the air blowing direction (claim 2).

In this configuration, the distribution plate changes the ratio of the amount of air blown to each of the plurality of air outlets in accordance with the rotational position of the airflow direction plate and the distribution plate, and the airflow direction plate changes the airflow direction by the guide plate. An air blowing direction is formed for an air outlet different from the air outlet. Therefore, the air is reliably guided by the guide plate to the outlet from which the air is not guided by the wind direction plate.

(3) The wind direction plate closes any one of the plurality of outlets at a predetermined rotation position, and the distribution plate closes another one of the plurality of air outlets at another predetermined rotation position of the wind direction plate. Is closed (claim 3).

In this configuration, each of the plurality of outlets is selectively closed by the wind direction plate and the distribution plate according to the rotational position of the wind direction plate. Therefore, by adjusting the rotation position of the wind direction plate, the air blowing from any of the plurality of outlets is selectively stopped.

(4) The wind direction plate is characterized by being constituted by a plurality of wind direction plates arranged in parallel at a plurality of positions in a direction orthogonal to the blowing direction at one outlet and rotating in conjunction with each other. (Claim 4).

In this configuration, a plurality of wind direction plates rotate in conjunction with one air outlet. Therefore, the moving range of the wind direction plate in the blowing direction at the outlet is reduced.

(5) In the configuration of (4), any one of the plurality of wind direction plates can be formed integrally with the distribution plate.

According to this structure, the structure of the operating member in the vicinity of the blowing section can be simplified.

(6) A link mechanism for interlocking the wind direction plate and the distribution plate while maintaining a parallel state with each other is provided (claim 5).

In this configuration, the wind direction plate and the distribution plate work together while maintaining a parallel state with each other via the link mechanism. Accordingly, the distribution plate reliably rotates with the wind direction plate, and the blowing direction is reliably defined in a direction passing between the wind direction plate and the distribution plate.

(7) The link mechanism includes a first link that rotates integrally with the wind direction plate at one end, a second link that rotates integrally with the distribution plate at one end, and the other end of the first link. And a third link connecting the other end of the second link with the third link.

In this configuration, the link mechanism for linking the wind direction plate and the distribution plate while maintaining the state parallel to each other is the simplest configuration. Therefore, there is no increase in cost and size of the apparatus due to the complicated structure.

(8) Two links adjacent to each other in the link mechanism operate in a rotation range including a position where an opening angle between the links is 180 degrees (claim 7).

In this configuration, in the rotation range where the opening angle of the two links is less than 180 degrees, the wind direction plate and the distribution plate rotate in parallel with each other, and in the rotation range where the opening angle of the two links exceeds 180 degrees. The angle between the wind direction plate and the distribution plate changes. Therefore, the interlocking state between the wind direction plate and the distribution plate changes according to the rotational positions of the wind direction plate and the distribution plate.

(9) In the link mechanism, two adjacent links operate in a rotation range in which an opening angle between each other exceeds 180 degrees after the wind direction plate closes one of the outlets. (Claim 8).

In this configuration, any one of the wind direction plates is provided.
In a state where the two outlets are not closed, the wind direction plate and the distribution plate can be rotated in parallel with each other in a rotation range where the opening angle of the two links is less than 180 degrees,
After the wind direction plate closes any one of the outlets, the distribution plate (however, the distribution plate is integrally formed with any one of the plurality of wind direction plates) in a rotation range where the opening angle of the two links exceeds 180 degrees. In this case, only the distribution plate and the wind direction plate integrally formed can be rotated.

(10) An elastic member for radially pressing the peripheral surface of the rotating shaft of the wind direction plate or the distribution plate is provided (claim 9).

In this configuration, the elastic force of the elastic member acts as a braking force against the rotation of the wind direction plate or the distribution plate. Therefore, the wind direction plate and the distribution plate interlocking with each other stop at an arbitrary rotation position.

(11) In the configuration of (10), it is possible to form an engaging portion that engages with a part of the circumferential surface of the rotating shaft of the wind direction plate or the distribution plate in the circumferential direction and the elastic member.

[0033] In this configuration, the wind direction plate and the distribution direction plate are engaged with each other in the circumferential direction of the circumferential surface of the rotation shaft of the distribution plate and the elastic member so that the wind direction plate and the distribution direction plate and the distribution plate interlock with each other. The distribution plate can be reliably stopped at a predetermined rotation position.

(12) A portion to which a rotational force acts is disposed near the position of the elastic member in the axial direction of the wind direction plate or the distribution plate (claim 10).

In this configuration, the part where the elastic force of the elastic member acts as a load and the part where the rotational force for the rotational operation acts are located close to the wind direction plate or the distribution plate in the axial direction. Therefore, the wind direction plate or the distribution plate does not twist due to the action of the rotational force.

(13) In the configuration of (12), the portion where the rotational force acts is a knob integrally formed on the wind direction plate or the distribution plate, or a rotating shaft to which the rotation of the motor is transmitted. can do.

In this configuration, the wind direction plate and the distribution plate can be rotated by the manual operation of the knob or the rotation of the motor without twisting the wind direction plate or the distribution plate.

It is an air-cleaning filter of apatite antibacterial specification or the like that also prevents the passage of x and the like.

As shown in FIG. 3, the blowing section 3 of the dehumidifier 1
Is constituted by an upper surface outlet 23 and a rear surface outlet 24. The blowout section 3 is provided with a first louver 16 and a second louver 17 that constitute the wind direction plate 22. As shown in FIGS. 4 and 8, the first louver 16 and the second louver 1
Both ends of 7 are respectively supported by shaft holes 20 and 21 formed in the wall surfaces 18 and 19 on the louver side. By rotating the knob 31 provided on the first louver 16 protruding from the upper surface air outlet about the shaft hole 20 and the rotation shaft 33, and adjusting the rotation angles of the first louver 16 and the second louver 17, As shown in FIGS. 4 to 6, the direction of the airflow passing through the upper surface outlet 23 can be changed, and the upper surface outlet 23 can be closed as shown in FIG.

The rear outlet 24 has a horizontal rib 25
Is arranged. Further, the distribution plate 6 is formed integrally with the first louver 16, and the distribution plate 6 rotates together with the first louver 16 about the shaft hole 20. Distribution plate 6
Extends upstream of the first louver 16 and the second louver 17 in the airflow direction in the direction of the arrow Y. For this reason, the distribution plate 6 has a function of distributing air to the upper surface outlet 23 and the rear surface outlet 24 according to the rotation angle of the first louver 16, and closes the rear surface outlet 24 as shown in FIG. You can also.

More specifically, as shown in FIG. 3, the distribution plate 6 is connected at a predetermined angle to the distribution plate 62 extending to the upstream side in the air flow direction in the arrow Y direction. And the guide plate 61. The distribution plate 62 distributes the air to the upper surface outlet 23 and the rear surface outlet 24 according to the rotation angle of the first louver 16 as described above. Further, the guide plate 61 is connected to the rear outlet 24 by the distribution plate 62.
The air distributed to the side is guided toward the rear outlet 24.

The first louver 16 is integrally formed with a knob 31 projecting upward from the upper surface outlet 23. First
The louver 16 and the distribution plate 6 are integrally connected by a connection plate 32. A rotating shaft 33 protrudes from the connecting plate 32 toward the wall surface 18. The rotation shaft 33 passes through the shaft hole 20 of the wall surface 18. From the second louver 17, the wall 1
The rotating shaft 34 protrudes from the side 8. The rotation shaft 34 passes through the shaft hole 21 of the wall surface 18. One end of a link 26 whose other end is pivotally supported on one end of a link 27 via a pin 29 is locked to the rotating shaft 33. The other end of the link 27 is pivotally supported via a pin 30 at one end of a link 28 having the other end locked to a rotation shaft 34. These links 26-
A link mechanism for linking the first louver 16 and the second louver 17 is constituted by 28.

That is, the knob 31 is operated to operate the first louver 16.
Is rotated about the shaft hole 20 and the rotation shaft 33, the link 26 fixed to the rotation shaft 33 rotates integrally with the first louver 16. The rotation of the link 26 is transmitted to the link 28 via the link 27, and the link 28 rotates in conjunction with the link 26. As a result of the rotation of the rotation shaft 34 with the rotation of the link 28, the second louver 17 having the rotation shaft 34 rotates in conjunction with the rotation of the first louver 16.

A part of the peripheral surfaces of the rotating shafts 33 and 34 are constituted by planes parallel to the shafts, and the rotating shafts 33 and 34 are formed in a D-shaped cross section. A hole having a shape corresponding to the cross-sectional shape of the rotation shafts 33 and 34 is formed at the end, and the rotation shafts 33 and 34 are fitted into the holes, whereby the links 26 and 28 are connected to the first louver 16 and the second louver 17. One end of the link 26 and the other end of the link 28 can be locked to the rotation shafts 33 and 34 so as to rotate integrally with the shaft 26.

As shown in FIG. 4, a leaf spring 34 is screwed to a boss extending downward from the upper surface of the housing, and the peripheral surfaces of the rotating shafts 33 and 34 are connected to the rotating shafts 33 of the links 26 and 28. And 34 are pressed in the radial direction by the elastic force of the leaf spring 37 through the fitting portions with respect to the. Accordingly, the braking force always acts on the rotation of the rotating shafts 33 and 34, and the first louver 16 and the second louver 17 can be stopped at arbitrary rotation positions. Furthermore, this leaf spring 37
And the rotation shafts 33 and 3 in the link 26 or the link 28
The first louver 16 and the second louver 17 are rotated by, for example, a predetermined rotation such as a position at which the upper surface outlet 23 is fully closed by forming irregularities which engage with each other on a part of the peripheral surface of the fitting portion with respect to the upper surface 4. It can also be reliably stopped in position.

By causing a part of the leaf spring 37 to abut on the side surface of the link 26 or the link 28 in the axial direction, the movement of the link 26 and the link 28 in the axial direction is restricted by the part of the leaf spring 37. The link 26 and the link 28 can be prevented from coming off from each of the rotating shafts 33 and 34.

In a state where the wind direction plate 22 composed of the first louver 16 and the second louver 17 is at the rotation position shown in FIG. 3,
The air blown from the inside of the dehumidifier 1 in the direction of arrow Y is distributed by the distribution plate 62 of the distribution plate 6 toward the upper surface outlet 23 and the rear surface outlet 24. The air distributed toward the upper surface outlet 23 is blown obliquely upward and rearward from the upper surface outlet 23 by the first louver 16 and the second louver 17. The air distributed in the direction of the rear outlet 24 is surely guided to the rear outlet 24 by the guide plate 61 of the distribution plate 6, and is blown from the rear outlet 24 to the rear of the dehumidifier 1 by the rib 25. In the distribution plate 6, the guide plate 61 is continuous with the distribution plate 62 at a predetermined angle, so that the air distributed by the distribution plate 62 in the direction of the rear outlet 24 is distributed along the distribution plate 62 along the upper surface outlet 23. The air flowing in the direction of the rear outlet 24 can be reliably guided to the rear outlet 24.

When the wind direction plate 22 composed of the first louver 16 and the second louver 17 is in the rotation position shown in FIG. 4, the distribution plate 62 of the distribution plate 6 is substantially vertical, and an arrow is drawn from inside the dehumidifier 1. Most of the air blown in the Y direction is the upper surface outlet 23.
After being guided in the direction, the first louver 16 and the second louver 17
Thus, the air is blown upward from the upper surface outlet 23. On the other hand, almost no air is guided in the direction of the rear outlet 24, and the amount of air blown out from the rear outlet 24 is extremely smaller than the amount of air blown out from the upper surface outlet 23.

In the state where the wind direction plate 22 composed of the first louver 16 and the second louver 17 is at the rotation position shown in FIG. 5, since the distribution plate 6 closes the rear outlet 24, the dehumidifier 1
All of the air blown in the direction of arrow Y from inside is guided toward the upper surface outlet 23. The air guided toward the upper surface outlet 23 is directed by the first louver 16 and the second louver 17.
The air is blown obliquely upward on the front side from the upper surface outlet 23.

In a state where the wind direction plate 22 composed of the first louver 16 and the second louver 17 is in the rotation position shown in FIG. 7, the first louver 16 and the second louver 17 close the upper surface outlet 23. All of the air blown in the direction of arrow Y from the inside of the dehumidifier 1 is guided toward the rear outlet 24, and is blown from the rear outlet 24 to the rear of the dehumidifier 1 by the rib 25.

The first louver 16 and the second louver 17
In the state where the wind direction plate 22 is in the rotation position shown in FIGS. 3 to 5, the link 26 and the link 28 rotate in conjunction with each other so as to be parallel to each other, and the first louver 16 and the second louver 17 form. The angle β (16 degrees as an example) is maintained. On the other hand, when the wind direction plate 22 is in the rotation position shown in FIG. 7, the link 26 and the link 28 are not in a parallel positional relationship with each other, and the angle between the first louver 16 and the second louver 17 is the angle α. (For example, 32 degrees).

That is, when the first louver 16 is continuously rotated in the direction of arrow C by operating the knob 31 from the state shown in FIG. 5, the second louver 17 that rotates in conjunction with the first louver 16 also moves in the direction of arrow C. As shown in FIG. 6, when one end of the second louver 17 abuts on the front side of the upper surface outlet 23, the second louver 17 closes a part of the front side of the upper surface outlet 23. Stop the rotation in the state. During this time, the opening angle γ between the link 26 and the link 27 gradually increases.

The first louver 1 is further changed from the state shown in FIG.
6 is rotated in the direction of arrow C, and after the opening angle between the link 26 and the link 27 exceeds 180 degrees, as shown in FIG.
The first louver 16 closes a part of the rear surface side of the upper surface outlet 23. When the opening angle between the link 26 and the link 27 coincides with 180 degrees, the linear distance from the rotation shaft 20 to the pin 30 becomes the longest. However, due to the elastic deformation of the link 26 and the link 27 in the axial direction, the link 26 The first louver 16 can be continuously rotated until the opening angle between the first louver 16 and the link 27 exceeds 180 degrees. In the state shown in FIG. 7, as an example, the opening angle between the link 26 and the link 27 is set to (360 degrees−γ).

In the state shown in FIG. 7, even when no rotational force acts on the first louver 16, the wind direction plate 22 and the distribution plate 6 try to rotate in the direction of arrow D by their own weight. Therefore, in order to maintain the state in which the upper surface outlet 23 is closed by the wind direction plate 22 (the state shown in FIG. 7), a means for reliably restricting the rotation of the rotating shafts 33 and 34 in this state is required. Therefore, the rotation of the rotating shafts 33 and 34 is regulated by using the leaf spring 37 shown in FIG. For example, a convex portion is formed at a position where the leaf spring 37 comes into contact with the peripheral surface of the portion of the link 26 fitted to the rotary shaft 33, and the wind direction plate 22 is formed on the peripheral surface of the portion of the link 26 fitted to the rotary shaft 33. When the upper surface outlet 23 is closed, a concave portion is formed at a position where the leaf spring 37 contacts, and the concave portion formed on the link 26 and the convex portion formed on the leaf spring 37 engage to rotate through the link 26. The rotation of the shaft 33 is restricted. With this configuration, the state in which the wind direction plate 22 closes the upper surface outlet 23 can be reliably maintained, and the elastic force of the leaf spring 37 is used to operate the knob 31 when the upper direction outlet 23 is opened and closed by the wind direction plate 22. Click feeling.

When the first louver 16 is rotated in the direction of arrow D from the state shown in FIG. 7, the rotation of the first louver 16 in the direction of arrow D until the opening angle between the link 26 and the link 27 matches 180 degrees. The rotation is transmitted to the link 28 and the second louver 17 via the link 27 as rotation in the direction of arrow C, and the second louver 17 is shown in FIG. 7 until the opening angle between the link 26 and the link 27 becomes less than 180 degrees. Stopped in position. When the opening angle between the link 26 and the link 27 becomes less than 180 degrees, the rotation of the first louver 16 and the link 26 in the direction of the arrow D is transmitted to the link 28 and the second louver 17 via the link 27 as the rotation of the direction of the arrow D. Then, the second louver 17 rotates in conjunction with the first louver 16 while maintaining the parallel positional relationship between the link 26 and the link 28.

When the opening angle between the link 26 and the link 27 coincides with 180 degrees, the operating force to be applied to the knob 31 to rotate the first louver 16 is maximized. A click feeling can be given to the opening / closing operation of the upper surface outlet 23 by the 22, and the operation of the first louver 16 by the knob 31 can be reliably performed.

As shown in FIG. 8, the knob 31 is formed near one end of the first louver 16 on the side where the link mechanism is disposed. With this configuration, it is necessary to rotate the first louver 16 and the second louver 17 against the pressing force of the leaf spring 37 against the fitting portions of the links 26 and 28 with the rotating shafts 33 and 34, and Since the operating force of the first louver 16 and the second louver 17 increases near the position where the upper surface outlet 23 is closed, it is possible to prevent the first louver 16 from being twisted by the operating force applied to the knob 31. When the leaf spring 37 directly presses a part of the peripheral surface of the rotating shafts 33 and 34 in the radial direction directly without passing through the links 26 and 28, the leaf spring 37 is in the axial direction of the first louver 16. Can be selectively arranged at any of both ends.

Further, as shown in FIG.
6, for example, a stepping motor 40 for supplying rotation in both forward and reverse directions to the rotating shaft 33
By controlling the rotation of the dehumidifier 1, the upper outlet 2
It is possible to automatically adjust the direction and amount of air blown from the third and rear outlets 24. The air outlet 3 is formed by projecting from the upper surface of the main body case. The air outlet 3 is formed by an opening in two or more directions, such as from the upper surface to the rear surface, and a wind direction plate 22 for adjusting the blowing direction. Therefore, the blowing direction range is wide.

Incidentally, the side cross-sectional shape of the blow-out portion 3 protruding from the upper surface of the main body case can be a partial ellipse, rectangle, trapezoid or triangle instead of the partial circle shown in the above embodiment.

Further, the air resistance acting on the first louver 16, the second louver 17 and the distribution plate 6 in response to the inclination angle of the first louver 16, the second louver 17 and the distribution plate 6 with respect to the air blow from the blower inside the main body in the direction of the arrow Y changes. Wind direction plate 22 and distribution plate 6
By adjusting the rotation angle, the wind speed of the air blown from the outlet also changes. In this way, the blowing direction range is wide,
Since the configuration is such that the wind speed from the outlet can also be changed, for example, the stepping motor 40 that supplies the rotational force to the rotating shaft 33 or 34 is repeatedly and continuously rotated in both the forward and reverse directions within a predetermined rotation range. 1st louver 16, 2nd
By repeatedly swinging the louver 17 and the distribution plate 6, it is possible to blow dry air uniformly over a wide area above the dehumidifier 1. Thus, even when the object to be dried is dried using the dehumidifier, the dried air uniformly contacts a wide range of the object to be dried, and the object to be dried can be quickly dried.

Furthermore, since the operation unit and the display unit in a state of being inclined are arranged on the front surface of the blow-out unit 3 formed so as to protrude above the main body, the operation of the operation unit and the visual recognition of the display unit can be easily performed. it can. In particular, when a liquid crystal display is used as the display unit, the visibility can be significantly improved. In this case, since the operation unit and the display unit are arranged above the front of the main body case, air cannot be blown in the horizontal direction on the front side of the main body case. However, on the rear side of the main body case, a sufficient amount of air can be blown from the rear outlet 24 into a wide range including the horizontal direction.

Even if the motor itself rotates only in one direction, the same effect can be obtained by providing a transmission mechanism for selectively transmitting rotation in one direction of the motor to the rotation shaft 33 in both forward and reverse directions. Obtainable. In addition, wind direction board 2
In order to prevent the first louver 16 from being twisted when automatically rotating the second louver 16, it is preferable to arrange a motor on the side of the first louver 16 where the link mechanism is arranged.
