However, if the vertical wind direction plate is rotated by shifting the shaft hole of the central bearing plate, a rotation trajectory of the vertical wind direction plate is generated in the central portion, so that the rotational torque at the time of rotation of the vertical wind direction plate becomes high. As a result, a high torque motor is required to rotate the vertical wind direction plate. Further, if the rotational torque is insufficient, there is a problem that the rotational operation of the vertical wind direction plate becomes defective, the shaft of the vertical wind direction plate and the shaft hole of the bearing plate are worn, and the parts are damaged.

The present invention has been made to solve the above problems, and is an air conditioner capable of smoothly rotating the vertical wind direction plate while causing and holding the vertical wind direction plate in a warped manner. The purpose is to provide an indoor unit.

The indoor unit of the air conditioner according to the present invention has a housing in which a suction port and an air outlet are formed, and is arranged inside the housing, sucks air from the suction port, and blows air-conditioned air.

It includes a vertical airflow direction plate for adjustment and an outlet assembly having a support mechanism for rotatably supporting the vertical airflow direction plate, and a shaft of rotation of the vertical airflow direction plate at both ends of the air outlet assembly in the longitudinal direction. The core is located on the same straight line extending in the longitudinal direction, and the axis of rotation of the vertical airflow direction plate at the central portion in the longitudinal direction of the outlet assembly is deviated from the straight line toward the vertical airflow direction plate. The vertical wind direction plate is located at a position, and is configured to be guided along an arc-shaped locus in the central portion when rotating, and the arc-shaped locus is a plurality of arcs having different radius of curvature. The adjacent arcs among the plurality of arcs have a common tangent line, and the radius of curvature of the plurality of arcs changes between both ends of the arc-shaped locus .

According to the indoor unit of the air conditioner according to the present invention, since the axis of rotation of the vertical wind direction plate in the central portion in the longitudinal direction of the air outlet assembly is located at a position shifted to the side of the vertical wind direction plate, the vertical wind direction The plate is pressed against the support mechanism. Then, when the vertical wind direction plate rotates in this state, the vertical wind direction plate is guided along an arcuate locus at the central portion. Therefore, when rotating the vertical wind direction plate, rattling in the support mechanism is prevented, and it is not affected by the air blown out from the air outlet and the vibration of the indoor unit, so that the generation of abnormal noise should be prevented. Can be done. Further, since a high torque is not required when rotating the vertical wind direction plate, damage to the vertical wind direction plate and the support mechanism is prevented.

It is positioned in. As a result, the vertical wind direction plate 4 is in a state in which the intermediate portion thereof protrudes outward of the indoor unit 100 as compared with both end portions and is bent. Further, an urging force acts on the central shaft 43a in the direction from the position where it is fitted with the central shaft hole 83a toward the point AX, and the central shaft 43a is always on the inner peripheral surface of the central shaft hole 83a. It is in a state of being pressed against the inner part of the indoor unit 100. In this state, the vertical wind direction plate 4 rotates between the closed position of FIG. 9 and the open position of FIG. 10 based on the control of the control unit (not shown) arranged in the indoor unit 100.

FIG. 11 is a diagram for explaining the shape of the central shaft hole of the support member of the outlet assembly. The portion of the inner peripheral surface of the central shaft hole 83a on the indoor unit 100 side has a first arc C1, a second arc C2, and a third arc C3. The first arc C1 having the center of curvature P1 and the second arc C2 having the center of curvature P2 are adjacent to each other and have a common tangent line L1. The radius of curvature of the second arc C2 is larger than the radius of curvature of the first arc C1. The second arc C2 and the third arc C3 having the center of curvature P3 are adjacent to each other and have a common tangent line L2. The radius of curvature of the third arc C3 is larger than the radius of curvature of the second arc C2. As described above, on the inner peripheral surface of the central shaft hole 83a, the shape of the inner side portion of the indoor unit 100 is a curve connecting a plurality of arcs having different radii of curvature, and the arcs adjacent to the plurality of arcs are adjacent to each other. Have a common tangent. The first arc C1 is located on the front panel 2 side of the indoor unit 100, and the third arc C3 is located on the back side of the indoor unit 100. That is, the radii of curvature of the plurality of arcs forming the inner shape of the indoor unit 100 on the inner peripheral surface of the central shaft hole 83a gradually change from the front panel 2 side toward the back side of the indoor unit 100. There is.

When the vertical wind direction plate 4 is in the closed position of FIG. 9, the central axis 43a is located at the end of the first arc C1 having the smallest radius of curvature. Therefore, the shaft core of the central shaft 43a is located at the position closest to the straight line extending in the longitudinal direction of the vertical wind direction plate 4 in which the shaft core of the left shaft 41a and the center of the right shaft hole 42a are located. Further, when the vertical wind direction plate 4 is in the open position in FIG. 10, the axis of the central shaft 43a is located at the end of the third arc C3 having the largest radius of curvature. Therefore, the shaft core of the central shaft 43a is located at the position farthest from the straight line extending in the longitudinal direction of the vertical wind direction plate 4 in which the shaft core of the left shaft 41a and the center of the right shaft hole 42a are located.

In FIG. 11, the circle C11 including the first arc C1 and centered on the center of curvature P1, the circle C21 including the second arc C2 and centered on the center of curvature P2, and the curvature including the third arc C3. Circles C31 centered on the center P3 are shown by dotted lines.

As described above, the central shaft 43a of the vertical wind direction plate 4 is urged to the inner side portion of the indoor unit 100 on the inner peripheral surface of the central shaft hole 83a of the support mechanism 8. Therefore, when the vertical wind direction plate 4 rotates between the closed position of FIG. 9 and the open position of FIG. 10, the vertical wind direction plate 4 has a first arc C1 and a second arc C1 on the inner peripheral surface of the central shaft hole 83a. It is guided along an arc-shaped locus formed by the arc C2 and the third arc C3.

According to the present embodiment, the central shaft 43a of the vertical wind direction plate 4 is always pressed against the inner side portion of the indoor unit 100 on the inner peripheral surface of the central shaft hole 83a of the support mechanism 8. There is. Therefore, the fitting of the central shaft 43a and the central shaft hole 83a does not rattle, and the fitting state is not affected by the air blown out from the air outlet 1b and the vibration of the indoor unit 100. As a result, the generation of abnormal noise when the vertical wind direction plate 4 is stopped and when it is rotated is prevented.

Further, by fitting the central shaft 43a with the central shaft hole 83a at a position deviated from the point AX, the left shaft 41a is pressed against the inner peripheral surface of the left shaft hole 81a, and the right shaft 82a is inside the right shaft hole 42a. It is pressed against the peripheral surface. Therefore, the fitting of the left shaft 41a and the left shaft hole 81a and the fitting of the right shaft hole 42a and the right shaft 82a do not rattle, and these fitting states are affected by the air blown out from the outlet 1b. And it is not affected by the vibration of the indoor unit 100. As a result, the generation of abnormal noise when the vertical wind direction plate 4 is stopped and when it is rotated is prevented.

Further, since a high torque is not required when rotating the vertical wind direction plate 4, damage to each member of the vertical wind direction plate 4 and the support mechanism 8 is prevented.

On the inner peripheral surface of the central shaft hole 83a, the inner peripheral surface to which the central shaft 43a is pressed is composed of a plurality of arcs, that is, a first arc C1, a second arc C2, and a third arc. .. Therefore, by adjusting the radius of curvature of these arcs, the pressing force of the central shaft 43a against the central shaft hole 83a can be adjusted. As a result, when the wind direction of the air from the air outlet 1b is likely to vibrate, the pressing force can be increased.

As shown in FIGS. 9 and 10, in the present embodiment, the central axis 43a of the vertical wind direction plate 4 is positioned at a position relatively close to the point AX when the vertical wind direction plate 4 is in the closed position, and is positioned up and down. When the wind direction plate 4 is in the open position, it is positioned at a position relatively far from the point AX. If the central axis 43a is closer to the point AX, the deflection of the vertical wind direction plate 4 becomes smaller. Comparing the length of the operating time and the length of the stopping time of the indoor unit 100, the stopping time is generally longer. Therefore, according to the present embodiment, it is possible to suppress the time for the vertical wind direction plate 4 to strongly bend. As a result, the deformation of the vertical wind direction plate 4 over time is suppressed, and the force for pressing the central shaft 43a against the inner peripheral surface of the central shaft hole 83a of the support mechanism 8 is suppressed when the vertical wind direction plate 4 is rotated. it can.

By shifting the axis of the central axis 43a from the straight line where the center of the left axis 41a and the center of the right axis hole 42a are located, a rotation trajectory is generated on the central axis 43a when the vertical wind direction plate 4 is rotated. According to the present embodiment, the rotation trajectory is matched to the shape of the inner side portion of the indoor unit 100 on the inner peripheral surface of the central shaft hole 83a. As a result, the rotational torque of the vertical wind direction plate 4 can be reduced.

Further, the arc-shaped shape on the inner side of the indoor unit 100 on the inner peripheral surface of the central shaft hole 83a is configured such that the adjacent arcs have a common tangent line among the plurality of arcs, and the adjacent arcs have a common tangent line. No steps or irregularities are formed on the surface. Therefore, when the vertical wind direction plate 4 rotates, the central shaft 43a is smoothly guided.

In the present embodiment, the shape of the inner peripheral surface of the central shaft hole 83a of the support mechanism 8 to which the central shaft 43a of the vertical wind direction plate 4 is pressed is composed of three arcs, but is not limited to this. The number of arcs may be four or more as long as the adjacent arcs are configured to have a common tangent line.
