11 is a diagram for explaining the indoor unit of the air conditioner according to Embodiment 1 of the present invention, and is a perspective view showing how to attach a part thereof (left front vertical air direction adjustment mechanism) to the indoor unit.

The method for installing the left front vertical air direction adjustment mechanism 20LF to the indoor unit 100 is as follows: First, insert the left front end mounting shaft 45LF protruding from the left end plate 40L into the left front of the left front vertical air direction adjustment mechanism 20LF. A front left end bearing 23LF of the arm 22LF is attached to the end (refer to FIG. 5 ).

Next, in the state where the left front center mounting shaft 29LF is inserted into the left front air direction adjustment plate bearing 25LF, the left front air direction adjustment plate guide 26LF is pressed against the outer periphery of the left front center support bearing 53LF of the left central support portion 50L. (Refer to Figure 11). In this way, the axis center of the left front center mounting shaft 29LF of the left front vertical air direction adjustment mechanism 20LF coincides with the axis center of the left front bearing 74LF of the left front ring part 70LF supported by the left central support portion 50L.

Therefore, by moving the left front sliding die 28LF to the right and inserting (embedding) the left front center mounting shaft 29LF into the left front bearing 74LF, the left front vertical air direction adjustment mechanism 20LF is mounted.

In addition, the same is true for the right front up and down air direction adjustment mechanism 20RF. In the state where the right front end installation shaft 45RF is inserted into the right front end bearing 23RF, the right front center installation shaft 29RF is inserted (embedded) into the right front. The right front bearing 84RF of the ring part 80RF completes the installation of the right front up and down air direction adjustment mechanism 20RF (not shown).

In this way, the left front vertical air direction adjustment mechanism 20LF and the right front vertical air direction adjustment mechanism 20RF are connected by the left front ring 70LF and the right front ring 80RF which are pressed against each other by the left front elastic body 60LF.

(rotation of left front up and down air direction adjustment mechanism and right front up and down air direction adjustment mechanism)

12 is a diagram illustrating the indoor unit of the air conditioner according to Embodiment 1 of the present invention, and is a main diagram showing a state where a part thereof (a left front vertical air direction adjustment mechanism and a right front vertical air direction adjustment mechanism) is connected; view.

In Fig. 12, in the state where the left front fitting protrusion 75LF enters the right front fitting notch 85RF, the phase of the left front with a cross section near the central mounting shaft 29LF (left front bearing 74LF) and the right front with a cross section are It is consistent with the phases of central installation shaft 29RF (right front bearing 84RF).

Therefore, when the left front vertical air direction adjustment mechanism 20LF and the right front vertical air direction adjustment mechanism 20RF are driven to rotate by the same angle, even if the rotation angle of the left front stepping motor 41LF is different from the rotation angle of the right front stepping motor 41RF Due to deviation by a small angle, the front left vertical air direction adjustment mechanism 20LF and the right front vertical air direction adjustment mechanism 20RF will also rotate by the same angle, so that the phases of the two after rotation are consistent.

In addition, similarly, the left rear vertical air direction adjustment mechanism 20LR and the right rear vertical air direction adjustment mechanism 20RR are rotated by the same angle, so that the phases of the two rotated are aligned. That is, since there is no angular deviation between the two, it is possible to obtain the indoor unit 100 with excellent appearance.

On the other hand, in the state where the left front fitting protrusion 75LF enters the right front fitting notch 85RF, when the left front vertical air direction adjustment mechanism 20LF and the right front vertical air direction adjustment mechanism 20RF are driven to rotate at different angles, the left The front elastic body 60LF is compressed, whereby the left front fitting protrusion 75LF is disengaged from the right front fitting notch 85RF, and the tip of the left front fitting protrusion 75LF is slid on the end surface of the right front sliding part 81RF, thereby making the left front The vertical air direction adjustment mechanism 20LF and the right front vertical air direction adjustment mechanism 20RF rotate by different angles. Accordingly, the conditioned air can be blown out in different directions in the vertical direction on each side of the air outlet 2b of the indoor unit 100 in the left-right direction.

(Opening angle of right front fitting incision)

13 to 15 are diagrams illustrating the indoor unit of the air conditioner according to Embodiment 1 of the present invention. FIG. Fig. 15 is a front view showing the relationship between the left front fitting protrusion and the right front fitting notch.

In Fig. 13 and Fig. 14, when the rotation angle difference between the left front air direction adjustment plate 21LF and the right front air direction adjustment plate 21RF is set as "ψ (psi)", the left front center installation shaft 29LF and the right front center The rotation angles of the mounting shafts 29RF differ only by "ψ".

In this way, in order to set the difference between the rotation angles of the left front air direction adjustment plate 21LF and the right front air direction adjustment plate 21RF of the indoor unit 100 to the minimum angle "ψ", when the center of the left front fitting protrusion 75LF fits with the right front When the center of the notch 85RF is shifted by an angle corresponding to the minimum angle "ψ", it is necessary not to pull the left front fitting protrusion 75LF toward the right front fitting notch 85RF (see FIG. 15 ).

That is, when the slight deviation due to the deviation of the rotation angles of the left front stepping motor 41LF and the right front stepping motor 41RF is smaller than the minimum angle "ψ", when the left front stepping motor 41LF and the right front step When the feed motor 41RF is driven to rotate them by the same angle, the left front fitting protrusion 75LF is drawn in toward the right front fitting notch 85RF. Therefore, the deviation in the rotation angle of the left front stepping motor 41LF and the like is absorbed, so that the left front air direction adjustment plate 21LF and the right front air flow direction adjustment plate 21RF are rotated by the same angle. Therefore, the opening angle "θ" is determined by the magnitude of the difference between the rotation angles of the left front stepping motor 41LF and the right front stepping motor 41RF and the difference between the rotation angles of the left front air direction adjustment plate 21LF and the right front air flow direction adjustment plate 21RF. set value to decide.

In addition, as shown above, the inner surface of the left front end bearing 23LF and the outer surface of the left front end mounting shaft 45LF have a Y-shaped section, and the inner surface of the left front wind direction adjustment plate bearing 25LF and the left front center The cross-section of the outer surface of the mounting shaft 29LF is cross-sectional, but the present invention is not limited thereto, as long as the bearing and the mounting shaft are connected so as to prevent relative rotation, the cross-sectional shape is not limited. For example, the cross section may be triangular or quadrilateral, or the cross section may be circular having a key groove sunk toward one outer surface and a key protruding toward the other outer surface.

In addition, the above shows the case where two vertical airflow direction adjustment mechanisms 20 are provided in the left-right direction, and two are provided in the front-rear direction, making a total of four. There are 3 sets of up and down wind direction adjustment mechanisms on the top.

At this time, for example, a central front vertical air direction adjustment mechanism (not shown) is provided between the left front vertical air direction adjustment mechanism 20LF and the right front vertical air direction adjustment mechanism 20RF. In addition, the right front near the center installation shaft 29RF and the left front near the center installation shaft 29LF are respectively provided at both ends of the central front vertical air direction adjustment mechanism.
