[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air outlet opening / closing device for an air conditioner provided with a louver for adjusting the wind direction at the air outlet.

[0002]

2. Description of the Related Art FIG. 12 is an external perspective view of an example of a conventional stationary air conditioner disclosed in Japanese Patent Application Laid-Open No. 9-42755. In FIG. 12, 100 is an air conditioner,
101 is the main body, 103 is an air outlet formed above the front surface of the main body 101, 104 is a horizontal louver provided on the opening side of the air outlet 103, and 105 is a rear side of the horizontal louver 104 of the air outlet 103. The vertical louver 106 is an air inlet formed below the front surface of the main body 101.

[0003] With this configuration, when the air conditioner 100 is operated, air is sucked from the suction port 106, and
After passing through a heat exchanger (not shown) disposed in a ventilation path inside the inside of the louver 10, the vertical and horizontal louvers 10
Hot air or cold air is sent from the air outlet 103 in a state where the wind directions in the left-right direction and the vertical direction are finely adjusted by 5, 104. Thereby, a desired air conditioning effect can be obtained in the space where the air conditioner 100 is installed.

FIG. 13 is an exploded perspective view of the inside of the air outlet of the air conditioner. As shown in FIG. 13, the periphery of the substantially rectangular outlet 103 is a frame 102 formed by bending a metal main body 101 into a U-shaped cross section. In FIG. 13, the frame portions 102 at the upper and lower ends of the outlet 103 are omitted.

Next, a procedure for attaching the horizontal louver 104 to the outlet 103 will be described. The five horizontal louvers 104 form a set, and a pair of first louver shafts 108, 108 are coaxially arranged along the longitudinal direction on both sides thereof. Further, slightly behind the first louver shaft 108 on the right side of the horizontal louver 104, a second louver shaft 109 having a size longer than the first louver shaft 108 is provided.
08 are provided along the longitudinal direction.

On the side surfaces 102a of the left and right frame portions 102, a pair of shaft holes 117, 117 facing each other at the same height are provided at five locations in a line at equal intervals. This round hole 11
7, the first louver shaft 108 of the horizontal louver 104 is inserted. The other end of an eccentric cam 111 having a cam shaft 112 at one end is rotatably attached to a motor shaft (not shown) of the motor 110. Accordingly, the cam shaft 112 of the eccentric cam 111 rotates around the motor shaft (not shown) with the rotation of the motor shaft (not shown). The cam shaft 112 has a substantially cylindrical shape, and a substantially central portion in the axial direction is a small-diameter portion 112a having an inner diameter smaller than other portions.

The elongated plate-shaped connecting member 113 has a shaft hole 1
14 are provided in a line at equal intervals as the shaft hole 117. A notch 115 is formed at a lower end of the connecting member 113 in a direction substantially orthogonal to the longitudinal direction.
The thickness of the connecting member 113 is selected to be substantially equal to the axial length of the small diameter portion 112a of the cam shaft 112. Therefore, by inserting the small-diameter portion 112a deep from the open end of the notch 115, the camshaft 112 can be securely fixed to the connecting member 113 without any positional displacement.

The connecting member 113 to which the motor 110 is fixed via the camshaft 112 in this way is held in the frame 102 on the right side of the outlet 103. Then, the horizontal first louver shafts 108 are inserted one by one into the shaft holes 117 of the left frame portion 102, and the shaft holes 117 of the right frame portion 102 at the same height as the shaft holes 117. Is inserted into the right first louver shaft 108. Further, the second louver shaft 109 is inserted into the corresponding shaft hole 114 of the connecting member 113 and connected. Finally, the cap 116 for preventing the detachment is fitted to the tip of the first louver shaft 108 on the left side.

The above operation is performed by five horizontal louvers 104.
Is completed, the assembly of the opening / closing device for the outlet 103 is completed. Although not shown, it is assumed that five vertical louvers 105 (see FIG. 14) having the same configuration are arranged in the back of the horizontal louver 104 in advance by the same procedure as described above.

[0010]

When the motor 110 is driven in the outlet 103 having the above configuration, the motor shaft (not shown) rotates, and the eccentric cam 1 is rotated.
The connecting member 113 is rotated in the same direction about the motor shaft (not shown) via 11. The rotation angle is set to 0 ° to 180 °. Thereby, the horizontal louver 10
4, the second louver shaft 109 rotates together with the connecting member 113, and in conjunction with this operation, the five horizontal louvers 104 are integrated around the first louver shaft 108 by an angle equal to the rotation angle of the connecting member 113. Will rotate.

FIG. 14 is a schematic side sectional view of the outlet. When the operation of the air conditioner 100 (see FIG. 12) is stopped, as shown in FIG. 14, the horizontal louver 104 is stationary at a position where there is no inclination, and the upper and lower ends of the adjacent horizontal louvers 104 overlap with each other. Outlet 103
Is closed. This prevents dust such as dust in the air from entering the inside of the main body 101 from the outlet 103.

When the operation of the air conditioner 100 (see FIG. 12) is started, a signal from a control unit (not shown) is output from the motor 110 in accordance with an operation mode such as cooling and heating and operating conditions such as a set temperature. To the motor 11 based on the signal.
0 (see FIG. 13) rotates the motor shaft (not shown) forward by a predetermined angle. The rotation of the eccentric cam 111 (FIG. 1)
3) is transmitted to a connecting member 113 (see FIG. 13) via a cam shaft 112 (see FIG. 13) of the connecting member 113.
(See FIG. 13) rotates in the same direction.

As a result, the horizontal louver 104 rotates forward (FIG. 1).
4 (in the direction of arrow R), and as shown in FIG.
As shown in FIG. 15B, the angle is appropriately changed approximately 30 ° downward or substantially horizontally. Thereby, the outlet 103
(See FIG. 12) The air blown out from the vertical louver 1
After the wind direction is adjusted in the left-right direction by 05 (see FIG. 12), the air is blown in a state where the vertical wind direction is appropriately adjusted by the horizontal louver 104.

The air conditioner 100 (see FIG. 12)
Is stopped, the motor 110 (see FIG. 13) is driven in reverse rotation by a command from the control unit (not shown), and the horizontal louver 104 again operates the blowout port 1 as shown in FIG.
03 returns to the closed state.

In this conventional air conditioner 110,
As shown in FIG. 13, only the first louver shaft 108 is disposed on the left side of the horizontal louver 104, while the second louver for coupling to the shaft hole 114 of the connecting member 113 is provided on the right side. A shaft 109 is separately provided together with the first louver shaft 108.

Therefore, the horizontal louver 104 has an asymmetrical shape in the left and right directions, and thus not only increases the manufacturing cost of parts, but also has a problem that the compatibility of parts between air conditioners having different specifications is poor. Also, five horizontal louvers 104
Because they rotate integrally, the inclination is always the same for any horizontal louver 104, and there is a problem that the wind direction can be adjusted only in a limited pattern.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and allows the louver to close the air outlet when the operation is stopped without changing the existing louver shape.

Although not shown, behind the horizontal louver 4, eight vertical louvers 5 having the same configuration (FIG. 1)
(See (b)) is provided in advance by the same procedure as above.

In the above configuration, when the motor shaft 8 of the first motor 7R is driven to rotate, the cam shaft 11 of the eccentric cam 9 rotates about the shaft stopper hole 10. As a result, the first connecting member 12R rotates in the same direction, and the camshafts 11 of the four eccentric cams 9 fitted into the shaft stopper holes 13 of the first connector 12R in conjunction therewith move the shaft stopper holes. It rotates around 10. At this time, since the first and second louver shafts 6R and 6L of each horizontal louver 4 belonging to the first louver group 4H are inserted through the pair of opposed shaft holes 17 of the frame portion 2, the first louver shaft 6R is connected.

For example, as shown in FIG. 6B, only the horizontal louvers 4 of the first louver group 4H can be inclined by 90 ° in the direction of R1 while the horizontal louvers 4 of the second louver group 4L are kept stationary. . In this case, the air accelerated from the upper half of the air outlet 3 can be transmitted to the distant place without changing the amount of air blown out by a fan or the like, which is advantageous for air conditioning at a location remote from the air conditioner 100. Becomes

As shown in FIG. 6 (c), the horizontal louvers 4 of the first louver group 4H are tilted slightly upward in the direction of R1, and the horizontal louvers 4 of the second louver group 4L are tilted slightly downward in the direction of R2. It can also be inclined. In this case, air is blown upward from substantially the upper half of the outlet 3 and air is blown downward from the substantially lower half of the outlet 3, so that the entire room can be efficiently emptied. An effect such as air conditioning can be expected.
