DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner in which the direction of conditioned air blown into a room can be changed by a wind direction adjusting plate.

[0002]

2. Description of the Related Art As is well known, for example, a separate type air conditioner includes an indoor unit and an outdoor unit. The indoor unit is mounted on an upper portion of a side wall in a room, and a blowout portion provided at a lower portion thereof has a horizontal portion. An outlet is provided so as to be elongated in the direction and open obliquely downward and forward, and conditioned air is blown into the room through the outlet. In addition, the air outlet is provided with an elongated wind direction adjusting plate whose both ends in the longitudinal direction and an intermediate portion are rotatably supported by the blowing portion by the respective shaft supporting portions so as to traverse the wind direction adjusting plate. Thereby, the elevation angle in the blowing direction of the conditioned air blown into the room from the blowing port can be appropriately changed.

The prior art will be described below with reference to FIGS. 9 and 10. FIG. 9 is a perspective view of the wind direction adjusting plate, and FIG.
FIG. 10 is a view showing a schematic configuration of the rotation support of the wind direction adjusting plate.
(A) is a side view of the wind direction adjustment plate viewed from the lateral direction, FIG.
(B) is the top view seen from the ventral side of the wind direction adjustment plate.

In FIG. 9 and FIG. 10, a wind direction adjusting plate 1 has an elongated rectangular shape, and a cross-sectional shape in a lateral direction of a wind direction changing portion, which is a main portion thereof, is thick at an intermediate portion and both lengths are large. It has a substantially airfoil shape that gradually becomes thinner toward the marginal direction, and the rear surface corresponding to the upper surface of the airfoil has a convex shape. Further, the wind direction adjusting plate 1 is provided with a support plate 2a standing upright at one end in the longitudinal direction on the abdominal surface corresponding to the lower surface side of the airfoil. An end support shaft 3 having an axial center direction parallel to the longitudinal direction is fixed outward. Further, the wind direction adjusting plate 1 is provided with a support plate 2b upright at the other end in the longitudinal direction on the abdominal surface, and the same axis as the end support shaft 3 fixed to the support plate 2a from the support plate 2b. A rotating shaft 4 having a center is fixed outward. The rotation shaft 4 has a non-circular hole 4a.
Are formed. Further, a bearing plate 5 is provided on the wind direction adjusting plate 1 so as to stand upright at a central portion in the longitudinal direction on the abdominal surface side, and the bearing plate 5 has an end support shaft 3, a shaft center of the rotating shaft 4 and a hole. An intermediate bearing hole 6 having the same center is formed.

On the other hand, a blow-out port 8 provided at the lower portion of the indoor unit has a blow-out port 8 which is elongated and opens diagonally downward and forward, and has a one-end shaft support section 9 on one end side in the longitudinal direction. And a drive motor 1 for rotating the wind direction adjusting plate 1 within a predetermined rotation range, while forming an end support shaft 11 on the other end side.
2 are provided. The shaft 1 of the drive motor 12
Numeral 3 is formed in a non-circular shape, and the rotation center, which is the axis center of the shaft 13, is the same as the axis center of the end bearing 10. Further, an intermediate support plate 16 to which an intermediate support shaft 15 constituting the intermediate shaft support portion 14 is fixed is provided at a central portion of the outlet 8, and the center of the intermediate support shaft 15 is the center of the end bearing 10. It is the same as the rotation center of the shaft 13.

In the wind direction adjusting plate 1, an end support shaft 3 provided at one end is rotatably inserted into an end bearing 10 of a shaft support 9 at one end, and a rotation shaft provided at the other end. 4 is fitted into the shaft 13 of the drive motor 12 of the other end shaft support portion 11, and the intermediate bearing hole 6 provided in the intermediate portion is rotatably fitted into the intermediate support shaft 15 of the intermediate shaft support portion 14. Thus, it is attached to the outlet 7 of the indoor unit. The diameters of the fitted intermediate support shaft 15 and the intermediate bearing hole 6 are usually the same as those having a small gap required to be rotatable between them. Have approximately the same dimensions. In addition, the wind direction adjusting plate 1 attached to the blowing section 7 has the rear side facing the indoor side when the blowing port 8 is closed so as to restrict the blowing of air.

With this configuration, when the operation of the air conditioner is started and conditioned air is blown into the room from the outlet 8 of the indoor unit, the conditioned air is rotated by rotating the wind direction adjusting plate 1. The air is blown into the room with the flow direction changed so as to follow the inclination angle of the wind direction adjusting plate 1. For this reason, the conditioned air is blown out in a substantially horizontal direction from the outlet 8 opening toward the diagonally lower forward direction of the indoor unit when, for example, the wind direction adjustment plate 1 is rotated so that the abdominal surface is horizontal. .

The wind direction adjusting plate 1 is rotated so that one longitudinal side is upstream in the blowing direction and the other longitudinal side is obliquely downward and forward in the blowing direction downstream. Then, the conditioned air is blown out by the wind direction adjusting plate 1 with the flow direction directed obliquely downward and forward, and the wind direction adjusting plate 1 is further rotated so that the other longitudinal side is in the vertical downward direction downstream of the blowing direction. In the moved state, the conditioned air is blown substantially vertically downward. Further, by continuously operating the drive motor 12 simultaneously with the operation of the air conditioner, the wind direction adjustment plate 1 is rotated within a predetermined rotation range, whereby the conditioned air is blown while continuously changing the elevation angle in the blowing direction. Is done.

Since the wind direction adjusting plate 1 provided in the blowing section 7 to change the blowing direction of the conditioned air is usually a thin plate having a length of about 1 m in the longitudinal direction,
The central portion tends to bend in the thickness direction, for example, in the direction of arrow A as shown by the two-dot chain line in FIG. For this reason, if the wind direction adjusting plate 1 is rotated to support only both ends and change the blowing direction, various inconveniences occur. However, as described above, the intermediate shaft support 14 is provided at the center of the outlet 8, and the wind direction adjusting plate 1 is thin and easy to bend. The center portion is supported by the intermediate shaft support portion 14 in which the support shaft 15 and the intermediate bearing hole 6 are fitted, the bending in the direction of arrow A is easily corrected, and the inconvenience that occurs when only the both ends are supported is eliminated.
The rotation direction of the conditioned air is changed by smoothly rotating around the same shaft center as the shaft 13 and the end support shaft 3 of the drive motor 12.

However, in the above prior art,
Since the wind direction adjusting plate 1 has a thin and long plate shape, bending in the plate thickness direction is likely to occur in the longitudinal direction, but can be easily corrected, and can be smoothly rotated even when the intermediate shaft support portion 14 is supported. For example, as shown by a two-dot chain line in FIG.
The warp deformation of the sword in the direction of the arrow, such as the warp of the sword, has a large rigidity and requires a large force to correct, and the correction is not easy. When the central portion of the wind direction adjusting plate 1 having the warp deformation in the direction of the arrow B is to be supported by the intermediate shaft supporting portion 14, the intermediate bearing hole 6 and the intermediate supporting shaft 15 are forcibly fixed while correcting the displacement. It is difficult to assemble. In addition, even in the fitted state, the frictional force between the intermediate bearing hole 6 and the intermediate support shaft 15 is large, and a large torque is required to rotate the intermediate bearing hole 6 and the intermediate support shaft 15. Disappears. Furthermore, wind direction adjustment plate 1
If it is attempted to form the slab by extrusion molding, which is easy to process, warpage in the direction parallel to the surface is apt to occur, and the problem that the frictional force increases in the intermediate shaft support 14 frequently occurs. There is a fear.

[0011]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide an elongated rectangular wind direction adjusting plate having a warp deformation in a direction parallel to a plane. In this case, it is possible to easily perform the rotation support with a small frictional force at the intermediate shaft support portion, and to perform the smooth rotation operation even at a low torque, and to make the machining easier and less expensive.

Further, the wind direction adjusting plate 30 has an abdominal surface 30.
A bearing plate 34 is provided so as to be upright at a central portion in the longitudinal direction on the side b.
2. An intermediate bearing hole 35 which forms an intermediate shaft support portion 29 having the same axis center as the axis center of the rotating shaft 33 is formed. As shown in FIG. 3, the intermediate bearing hole 35 has an elliptical shape formed such that the major axis direction is parallel to the lateral direction of the wind direction adjusting plate 30. The intermediate support shaft 36 of the intermediate shaft support portion 29 has a dimension that can be moved in the major axis direction by a predetermined range, and the minor axis has a small dimensional difference with the diameter of the intermediate support shaft 36 such that smooth rotation is possible. It is equal.

On the other hand, the outlet 26 opening to the outlet 25 provided at the lower part of the indoor unit is provided with an end bearing 37 of a one-end shaft support 27 at one end in the longitudinal direction, and the other end. On the side, a drive motor 38 which constitutes the other end portion shaft support portion 28 and drives the wind direction adjusting plate 30 to rotate within a predetermined rotation range is provided. This drive motor 38
The cross section of the shaft 39 is formed in a non-circular shape so that the tip portion of the shaft 39 is fitted into the non-circular hole 33a of the rotation shaft 33 of the wind direction adjusting plate 30 as shown in FIG. The center of rotation, which is the axis center, is the same as the axis center of the end bearing 37. Further, an intermediate support plate 40 to which an intermediate support shaft 36 of the intermediate shaft support portion 29 is fixed is provided at a central portion of the outlet 26, and a center of the intermediate support shaft 36 is a shaft center of the end bearing 37 and a shaft 39. And the same rotation center.

The wind direction adjusting plate 30 has an end support shaft 32 provided on one end side, and the end bearing 3 on one end side of the blowout portion 25.
7, a rotation shaft 33 provided at the other end is fitted into a shaft 39 of a drive motor 38 provided at the other end, and an intermediate bearing hole 35 provided at an intermediate portion. Is rotatably fitted to the intermediate support shaft 36 of the intermediate support plate 40, and thus is attached to the blowout portion 25 of the indoor unit 21. In addition, the wind direction adjusting plate 30 attached to the blowing unit 25 has a rear surface 3 when the blowing port 26 is closed so as to restrict the blowing of air.
The 0a side faces the indoor side.

With this configuration, when the operation of the air conditioner is started and the conditioned air is blown into the room from the outlet 26 of the indoor unit 21 by rotating the wind direction adjusting plate 30, the conditioned air is rotated. Is blown into the room with the flow direction changed so as to follow the inclination angle of the wind direction adjusting plate 30. For this reason, from the outlet 26 that opens obliquely downward and forward in the lower part of the main body 22 of the indoor unit 21, for example, when the wind direction adjustment plate 30 is turned so that the abdominal surface 30b is horizontal, the wind direction adjustment plate 30 is substantially horizontal. The conditioned air is blown out.

The wind direction adjusting plate 30 is inclined such that one longitudinal side is downstream in the blowing direction, that is, upstream of the air flow path in the main body 22, and the other longitudinal side is oblique in the blowing direction downstream. In the state where the conditioned air is turned to the lower front direction, the conditioned air is blown out by the wind direction adjusting plate 30 with the flow direction directed obliquely downward and forward, and the wind direction adjusting plate 30 is blown out at the other longitudinal side. In a state where the air is rotated downward in the vertical direction on the downstream side in the direction, the conditioned air is blown substantially downward in the vertical direction. In addition, by continuously operating the drive motor 38 simultaneously with the operation of the air conditioner, the wind direction adjustment plate 30 smoothly rotates within a predetermined rotation range, whereby the conditioned air automatically raises the elevation angle in the blowing direction. It is blown out while changing continuously.

As described above, the wind direction adjusting plate 30 provided on the blow-out portion 25 usually has a length in the longitudinal direction of one.
The center portion is easily bent in the plate thickness direction because of the thin plate shape of about m, but the bending can be easily corrected.

Even when the center of the hole is deviated from the center of the end support shaft 32 and the rotation shaft 33, the intermediate bearing hole 35 is oblong, so that even when the wind direction adjusting plate 30 is attached to the blowing portion 25, It can be easily rotatably fitted to the intermediate support shaft 36.

Further, when the wind direction adjusting plate 30 is rotated, an oval intermediate bearing hole 35 is formed with respect to the intermediate support shaft 36.
Is fitted at a position shifted in the major axis direction, so that it rotates at a position shifted from the center of the intermediate bearing hole 35. As a result, the frictional force at the turning portion is small, and the wind direction adjusting plate 30 rotates. The torque required for the movement is not large, and the rotation can be performed smoothly even at a low torque. Further, although the intermediate bearing hole 35 has an elliptical shape, its short diameter is substantially equal to the diameter of the intermediate support shaft 36 with a small dimensional difference in a range that allows smooth rotation.
The wind direction adjusting plate 30 is pushed by the conditioned air that is blown out, and noise generated by vibrations due to this is also minimized.

Although the intermediate shaft support 29 in the above embodiment is provided only at the center of the outlet 26,
It may be provided at a plurality of locations, and may be configured as follows. That is, as shown in FIG. 5, the intermediate shaft support portion 41 is provided with an intermediate support shaft 42 provided on the intermediate support plate 40.

5, the intermediate bearing hole 35 of the bearing plate 34 provided at the center of the wind direction adjustment plate 30 is fitted to the intermediate support shaft 42 formed by inserting the sleeve 44 into the support shaft 43. Is performed. By doing so, the frictional force of the rotating portion at the intermediate shaft support portion 41 becomes smaller, and the smooth rotation of the wind direction adjusting plate 30 with lower torque can be performed. The same operation and effect as those of the embodiment can be obtained.
