Field of the Invention The present invention relates to a portable air conditioner such as a dehumidifier, and more particularly, to an air blowing unit capable of adjusting the blowing direction of air blown from the portable air conditioner in a wide range. Regarding the structure.

[0002]

2. Description of the Related Art A conventional technique will be described by taking a dehumidifier having a drying function as an example. A conventional laundry dryer has a drying chamber for storing laundry as an article to be dried and sends dry air to dehumidify the air, but the air around the drying chamber flows into the drying chamber. However, it is necessary to seal the drying chamber in order to prevent the dehumidifying effect of the drying room air from decreasing, and because the drying chamber is provided, the product housing becomes large, requiring a large area for installation. Had the drawback of.

Therefore, hanging laundry in a small room,
There is a method in which a portable dehumidifier is brought in and the laundry is dried by dehumidifying operation. The sales of a portable dehumidifier with a drying function used for such a purpose have recently been strong.

When the dehumidifier with a drying function is strongly blown toward the laundry, the laundry can be dried more effectively. Therefore, in this dehumidifier with drying function,
It is required to change the wind direction of the air blown from the blowout portion to a wide range as much as possible.

Regarding the air blowing portion of a portable air conditioner, as a conventional technique capable of changing the blowing direction of air in a wide range, for example, one described in Japanese Patent No. 2581773 is known. 8 (A), FIG. 8 (B), and FIG.
(C) is a cross-sectional view of the main part of the air outlet of the dehumidifier described in the above patent publication, in which a rotatable wind direction plate 53 is provided at the air outlet 52 of the cabinet upper surface 51 to make the air blowing direction variable. 8 (A) is a state of blowing in a diagonally upper front direction, FIG. 8 (B) is a state of blowing in a direction of the upper surface, and FIG.
(C) shows the operation stop state in which the air outlet is closed by the wind direction plate.

[0006]

In the air outlet of the dehumidifier as shown in FIG. 8, even if the air outlet 52 is provided on the upper surface 51 of the cabinet and the air flow direction is variable by the rotatable wind direction plate 53, the air blow direction is changed. There is a limit to changing the blowing direction in a wide range. That is, even if an opening is provided on the upper flat surface of the main body case of the dehumidifier to serve as an air blowing portion, it is difficult to blow air in the horizontal direction such as the front surface or the rear surface of the main body case. If the width is small and the depth is large and the blowing direction is variable in the left-right direction, it is difficult to blow the horizontal direction to the right side surface or the left side surface.

A portable air conditioner, for example, a dehumidifier with a clothes drying function is usually placed on the floor, so that the operation unit,
It is advantageous in terms of usability to arrange the display section diagonally above the front surface of the main body case. In particular, when a liquid crystal display device is used for the display section, it is advantageous to dispose the liquid crystal display device at the above-mentioned position because the viewing angle peculiar to the liquid crystal is limited.

The present invention has been made in view of the above problems, and it is possible to set a wide range of air blowing directions. For example, in the case of a dehumidifier having a clothes drying function, the object to be dehumidified and dried is desired. The aim is to be able to blow dry air directly onto.

[0009]

As shown in FIGS. 3 to 5, the upper surface outlet airflow direction control plate 22 has a first
By adjusting the rotation angles of the louver 16 and the second louver 17, the wind direction of the air flow passing through the upper surface outlet 23 can be controlled, and the upper surface outlet 23 can be closed as shown in FIG. .

The rear outlet 24 is a grill provided with horizontal ribs 25. The distribution plate 6 is integrally supported with the first louver 16 and is pivotally supported in the first shaft hole 20. The distribution plate 6 extends to the windward side of the blown air shown by the arrows from the first louver 16 and the second louver 17, and therefore blows out. It has a function of distributing the generated air to the upper surface outlet 23 and the rear surface outlet 24, and the rear surface outlet 24 can be closed as shown in FIG.

As shown in FIG. 3, the distribution plate 6 extends from the first louver 16 and the second louver 17 toward the air-blowing source side inside the main body shown by the arrows, and has an upper surface outlet 23 and a rear surface outlet 24.
A distribution plate 62 having a function of distributing the air flow rate to and
The distribution plate 62 is connected at an angle to surely blow the air distributed to the rear surface outlet 24.
And a guide plate 61 that guides the guide.

As shown in FIG. 4, a knob 31 is provided on the first louver 16 so as to project from the upper surface outlet 23.
When the knob 31 is rotated about the first rotation shaft 33 provided on the wing 32 in which the first louver 16 inserted into the shaft hole 20 and the distribution plate 6 are integrated, the first connecting plate 26 is rotated. ，
With the link mechanism constituted by the second connecting plate 27 and the third connecting plate 28, the second louver 17 also rotates about the second rotary shaft 34 provided in the second louver 17 inserted into the second shaft hole 21. And work together.

Next, the link mechanism will be described in detail. One end of the first connecting plate 26 is fixed to the first rotating shaft 33, and the other end is a first connecting shaft hole 29 provided in one end of the second connecting plate 27. Is provided with a first connecting shaft 35. One end of the third connecting plate 28 is fixed to the second rotating shaft 34, and the other end is provided with a second connecting shaft hole 30 that pivotally supports a second connecting shaft 36 provided at the other end of the second connecting plate 27. . Therefore, the first connecting plate 26 is also rotated by the rotation of the knob 31, and the third connecting plate 29 and the second connecting plate 30 are pivotally supported to rotate the third connecting plate 26 to the third connecting plate 27.
The connecting plate 28, and thus the second louver 17, is connected to the second rotating shaft 34.
Rotate around.

The first rotary shaft 33 and the second rotary shaft 34 are so-called D-cut having a D-shaped cross section, and the D-axis of the rotary shaft is provided at each one end of the first connecting plate 26 and the third connecting plate 28. A cylindrical shaft having a shaft hole that fits in the cut is provided, and the first rotary shaft 33 and the second rotary shaft 34 are inserted and fixed in the respective shaft holes. With the spring material 37 that is an elastic body, the first connecting plate 26, the third
The shaft surface of a cylindrical shaft having a shaft hole provided at each end of the connecting plate 28 is pressed to hold the wings 32 (first louver 16, distribution plate 6) and the second louver 17 at arbitrary rotation angle positions. be able to. In addition, a concave (or convex) is provided on the shaft surface of the cylindrical shaft having a shaft hole provided at each end of the first connecting plate 26 and the third connecting plate 28, and a convex (or concave) is provided on the spring member 37 side. It is possible to hold the louver at a predetermined rotation angle position by engaging the unevenness. Furthermore, after inserting the shaft hole of the cylindrical shaft provided at one end of the first connecting plate 26 into the D cut of the first rotating shaft 33,
By pressing one end of the first connecting plate 26 in the insertion direction at a portion branched from the spring material 37, the cylindrical shaft at one end of the first connecting plate 26 is prevented from coming off from the first rotating shaft 33.

Next, the operation of the upper surface outlet air flow direction control plate 22 at each rotational angle position will be described. At the position shown in FIG. 3, the air from the blower inside the main body indicated by the arrow is the distribution plate 6
The distribution plate 62 of the upper surface outlet 23 side and the rear surface outlet 24
The air flow direction is further controlled by the first louver 16 and the second louver 17 on the upper surface outlet 23 side, and air is blown out obliquely upward and rearward. Further, the air blown to the rear air outlet 24 side is surely guided to the rear air outlet 24 by the guide plate 61 of the distribution plate 6, and the horizontal ribs 25 of the rear air outlet 24 act as wind direction vanes (louvers). Blows air toward the rear. If the distribution plate 62 of the distribution plate 6 is not provided with the guide plate 61 that is continuous at an angle, the air blown to the rear air outlet 24 side is obliquely upward and rearward along the distribution plate 62, and the rear surface is blown. The air is not well guided in the direction of the outlet 24, the amount of air blown from the rear surface is reduced, and the oblique upward direction air blow becomes the main component, so that the wide air blow direction that is the object of the present invention cannot be achieved.

At the position shown in FIG. 4, since the distribution plate 62 of the distribution plate 6 is in the vertical position, most of the air from the blower inside the main body shown by the arrow is guided by the distribution plate 6 and the upper outlet 23 side. Blew upward from. The first louver 16 and the second louver 17 are also blown upward. Although there is some space in the air passage to the blower source side end of the distribution plate 6 and the rear surface outlet 24 side, there is almost no air blown to the rear surface outlet 24 side because the upper surface outlet 23 side is wide open.

At the position shown in FIG. 5, since the distribution plate 6 blocks the air passage to the rear air outlet 24 side, all the blown air flows to the upper air outlet 23 side, and the first louver 16 and the second louver 16 are provided. Since 17 is inclined obliquely forward, the air is blown obliquely upward and forward.

At the position shown in FIG. 6, the first louver 16 and the second louver 17 shield the upper surface outlet 23, so that all the blown air flows to the rear surface outlet 24 side. Distribution plate 6
Also shields the upper surface outlet 23. Therefore, the horizontal rib 25 of the rear surface outlet 24 also blows air toward the rear surface.

As described above, the blow-out portion 3 having a substantially arcuate shape in side section is formed by projecting from the upper surface of the main body case consisting of the front frame 1 and the rear frame 2, and the blow-out portion 3 is near the upper surface direction. To the rear surface direction to the two or more surface directions, and the first louver 16 and the second louver 17 for adjusting the blowing direction,
It is composed of a distribution plate 6 and a wind direction plate, and only by adjusting the knob 31, a rear surface blowing (FIG. 6), a wide range blowing from the rear surface to an obliquely upper rear surface (FIG. 3), an upper surface blowing (FIG. 4), an obliquely upper front surface. A wide range of blowing directions can be set from the rear surface to the obliquely upper front surface, such as blowing (FIG. 5).

Further, since the wind resistance differs depending on the inclination angle of the first louver 16, the second louver 17, and the distribution plate 6 with respect to the direction of the air blown from the air blower inside the main body shown by the arrow, what is the extent of the blowout range? The air blown from the outlet also changes depending on whether or not it is squeezed. The blow-out portion 3 protruding from the upper surface of the main body case has a semi-elliptical shape with a low protruding height instead of the substantially arc shape shown in the above-mentioned embodiment, a rectangular shape including three front, upper and rear surfaces, and an obliquely upper portion. It may be a protrusion having a trapezoidal shape composed of three surfaces of the front surface, the upper surface and the oblique rear surface, or a triangular shape composed of two surfaces of the oblique upper front surface and the oblique rear surface.

Regarding the position where the operation unit / display unit is provided, since it is a portable air conditioner that can be carried and is generally installed on the floor surface, the operation unit / display unit is provided on the upper front surface of the main body case. It is convenient to place the. Particularly, in the case of using a liquid crystal display device as a display unit, so we can not as visible from any direction because of the limited viewing angle, may appear as a position display contents when looking down from above, i.e. the main body case The display unit will be placed diagonally above and to the front.

In this way, as in the above-described embodiment, the operation / display unit 7 is provided on the obliquely upper front surface of the air blowing unit 3 protruding from the upper surface of the main body case, and the switch button for operation and the operating status are displayed. A liquid crystal display 38 is provided. For this reason, it is not possible to provide an outlet on the diagonally upper front surface of the outlet 3. However, since it is possible to blow air from the rear side, for example, in the case of a dehumidifier with a clothes drying function, if the laundry is placed in the rear direction instead of the front direction of the dehumidifier, the air blow in the horizontal direction can be used. In other words, even if there is no air blow in the front direction, it can be replaced by air blow in the rear direction. The present invention is not limited to the above embodiment.
